Near the end of July, the Nationals entered the Sunday finale of a four-game set in Milwaukee looking to win the series and wrap up a 6-1 road trip before heading home to face the rival Phillies. Things looked up as Steve Lombardozzi blasted the fifth pitch of the game – a 3-1 fastball from Milwaukee starter Mark Rogers – into the seats for an early lead. But the Brewers responded with two runs of their own in the first and led 3-1 heading to the sixth inning. From there, they seemed to answer every Nationals rally. Washington scored once in the sixth and seventh, but Milwaukee answered with two runs in each frame to build a 7-3 advantage. The Nationals roared back with four in the top of the eighth to tie the game, only to watch the Brewers score twice to take a 9-7 lead entering the ninth.
With one out in the top of the ninth, Mark DeRosa drew a walk to bring Michael Morse to the plate as the tying run. Brewers closer John Axford quickly got ahead 0-2, but when he tried to sneak a fastball over the outside corner, Morse reached out and belted it the other way down the line in right, just clearing the wall inside the foul pole for a game-tying, two-run home run. Thanks to 2.1 hitless innings of relief from Craig Stammen, the contest remained knotted at 9-9 into the top of the 11th, when Bryce Harper walked and Ryan Zimmerman singled, bringing up Morse once more. “The Beast” fell behind in the count again before hooking a 1-2 breaking ball down the left field line into the corner, scoring Harper easily and Zimmerman on a slide just ahead of the relay throw from shallow left field, pushing Washington in front, 11-9. Tyler Clippard hung on for the save in the bottom of the frame and the Nationals escaped the biggest roller coaster ride of the 2012 campaign with another Curly W in the books.
Earlier this week, Craig Stammen and Ross Detwiler departed on a once-in-a-lifetime opportunity. Personally invited by Chairman of the Joint Chiefs General Martin Dempsey, the two Nationals pitchers joined Capitals forward Matt Hendricks, country music singer Kellie Pickler and actor/comedian Iliza Shlesinger on a four-stop, seven-day USO holiday tour, visiting American troops overseas.
Due to the national security protocols involved in such a journey, not even the players themselves knew where they were headed as they took off to head overseas. All they were told was to pack for temperatures ranging from below zero to summer warmth in the 80s or 90s.
As exciting as the prospect of such a journey made the players, there was nevertheless some nervousness associated with heading into war-torn areas, not even knowing exactly what part of the world they would be visiting. One can only imagine how much that must have been amplified for Stammen, who had never been overseas before the tour. Detwiler, meanwhile, cut short his honeymoon in Hawaii to go on the trip.
Washington notched a dramatic victory on Opening Day in Chicago, but the Nationals saved some magic for their home opener against Cincinnati a week later, as well. Gio Gonzalez, making his first-ever home start in D.C., twirled seven sparkling innings of two-hit, shutout ball and recorded his inaugural Major League hit to boot, becoming an instant fan favorite in the District. Adam LaRoche delivered a clutch, two-out, two-run single in the fifth to push Washington ahead, but the Reds came back with a pair of runs in the ninth to tie the game and send it into extra innings.
But if any air had been let out of a raucous, packed house at Nats Park, Craig Stammen pumped it back up as he came on in the 10th inning. The converted starter, pitching in his first full season out of the Nats bullpen, struck out the side on just 10 pitches, one over the minimum. That set the stage for the late heroics, as Ryan Zimmerman was hit by a pitch to lead off the frame, moved to second on a one-out single by Jayson Werth, then to third on a groundout by Xavier Nady. That extra 90 feet proved to be crucial, as Alfredo Simon bounced an 0-1 slider to Roger Bernadina that squirted away far enough from catcher Devin Mesoraco for Zimmerman to scamper down the line and slide in safely with the first walk-off win of the season.
– SEE THE REST OF THE TOP 12 OF ’12 –
Stop us if this sounds familiar.
The Washington Nationals, trailing a tight, low-scoring game by one run in the top of the eighth inning, need a clutch hit late. This is, after all, their first time in such a position, with newfound expectations heaped on their collective backs, the attention of the sport and the nation at large turned to them for the first time in their young history. They need to find a way, through a raucous road crowd in one of baseball’s historic cities, to shut out the noise, the emotion, and find a way to win. Washington rides a three-hit day from Ian Desmond and a clutch hit late off the bench to a one-run road victory. It is Opening Day, April 5 in Chicago, and the Nationals have just beaten the Cubs to start the season.
Six months and two days later, Washington began its “second season,” the postseason, in remarkably similar fashion. The Nationals use another three-hit game from Desmond and a two-out, two-strike, two-run pinch-single – the very definition of clutch – from rookie Tyler Moore to a 3-2 victory over the St. Louis Cardinals in Game One of the National League Division Series. Of course, it was Chad Tracy who delivered the big blow on Opening Day, with his ninth-inning double. On Sunday afternoon, Tracy again played a role, despite never even crossing the lines onto the field of play. His announcement as the pinch-hitter for Ryan Mattheus (more on him later) in the top of the eighth prompted Cardinals Manager Mike Matheny to pull setup man Mitchell Boggs in favor of his lone lefty reliever, Mark Rzepczynski. Davey Johnson countered by pinch-hitting Moore, and the chess game continued. Matheny opted against a second pitching change, leaving right-handed closer Jason Motte in the ‘pen. Moore delivered. Checkmate.
Asked if it was the biggest hit in his career, Moore, the fresh-faced 25 year-old tucked into his stock, grey postseason sweatshirt, kept it simple.
“Uh, yeah,” he laughed.
However, none of those events would have transpired if not for the tremendous, history-making postseason debut of Nationals reliever Ryan Mattheus. Already leading 2-1 in the bottom of the seventh, St. Louis had loaded the bases with nobody out on an error, a single and a walk against Craig Stammen, prompting Johnson to go to his ground ball specialist. Even he couldn’t have imagined things would work out quite so well.
It wasn't pretty but we battled, the boys picked me up. Great job all around—
Gio Gonzalez (@GioGonzalez47) October 08, 2012
In a game in which the Cardinals seemed to constantly be on the verge of breaking out, Mattheus delivered in the biggest spot. For starters, he got cleanup man Allen Craig – a .400 hitter (50-for-125) with 74 RBI with RISP during the regular season – to hit the first pitch on the ground to shortstop, Desmond throwing home for the first out of the inning, the bases remaining loaded. Then, on the very next pitch, he induced an inning-ending 5-4-3 double play off the bat of 2012 All-Star Yadier Molina, becoming the first pitcher in the history of postseason play to record all three outs in an inning on just two pitches.
“I sold out to the ground ball,” he said with a smile after the nail-biting victory. “I’ve done it all year, that’s been my MO to get ground balls. Look at my numbers – I don’t punch very many guys out. So I’m not going to go in there and try to strike out the side.”
To call Mattheus an unknown factor would be an understatement. As the official scorer called out the afternoon’s final totals over the public address system in the press box, he mispronounced the reliever’s name, calling him “Math-A-us” rather than “Matthews,” though the right-hander surely could care less. He had just, after all, recorded the three biggest out of his career.
“Absolutely, no question about it,” Mattheus agreed when asked if Sunday’s performance topped his career highlights. “I don’t think we care if we stole it. Any one we can get is a win, no matter how we get it.”
Desmond had a different view of the outcome.
“I don’t think we stole it,” he said. “I think we earned it.”
Indeed, the Nationals earned it through a mix of quality pitching from the whole staff, combined with a couple of big hits in key spots. As anyone who has followed the team this year knows, that should come as no surprise.
“That’s really been the formula,” explained Desmond. “Just some timely hitting and some really, really good pitching.”
On that much, he and Mattheus agreed.
“I think that’s how this team’s been the whole year,” said Mattheus, reflecting back to Opening Day. “Some nights we pitch, some nights we hit. We try not to make too much of these games. Hopefully we can treat them like games in April. That was the most exciting day in my career so far, Opening Day, but this has to trump that.”
The Washington Nationals and Houston Astros opened their second and final series of the season with a pair of extra-inning games Monday and Tuesday night, and a pair of Nationals wins. But despite the apparent similarities, the defining plays of these two contests could not have been more different. We have already chronicled Houston’s defensive lapse from the 11th inning on Monday night that led to the game-winning run. However, to fairly and accurately chronicle the importance of Roger Bernadina’s jaw-dropping, game-saving catch for the final out of Tuesday night’s contest, we must look at it in the larger context – as a frontrunner for catch of the year in Major League Baseball.
Humor us, if you will. Watch the video below, no matter how many times you’ve already seen it, just so the play is fresh in your mind. Then, as we take you through our five reasons, we encourage you to read through each point individually, then watch the video again. By the end, you can tell us if you also believe that what the Shark reeled in last night was more impressive than any other catch made this season, including Mike Trout’s now legendary leap (video also below, for comparison).
Catch of the Year…Roger Bernadina
Or Mike Trout
1. The Amount of Ground Covered
Well positioned before the pitch, just to the left side of second base, Bernadina nevertheless had to run full tilt deep into the left-center field gap and leap, arms extended into the awkwardly shaped façade in front of the Nationals bullpen. But it’s not like he had time to set himself underneath the ball and try to time his leap – it was all on the run.
2. The Ballpark
Minute Maid Park is…unique. From the notoriously easy-to-reach Crawford Boxes in left field to Tal’s Hill in center field that rises behind the warning track and includes a foul pole in play, it is easy to forget the minefield that awaits outfielders in left-center. As you can see in the photo to the right, the angle of the wall changes every few feet, often causing awkward caroms and general confusion for visiting players trying to decide how to pursue fly balls in the area. Bernadina disregarded all of that, threw caution to the wind, and literally threw himself into one of the recesses of the wall, emerging with the ball.
3. The Game Situation
This cannot be overstated. After Washington had finally broken through in the top of the 12th with the first run scored by either team since the second inning, the Astros had the tying run at second and the winning run at first with two outs in the bottom of the frame. If Bernadina does not come up with that ball, the Astros not only tie it, they likely win the game on that play, with the runner on the move in the two-out situation. It’s that simple – the catch was literally the difference between a win and a loss. When is the last time you’ve seen that in a game?
4. Steve Pearce/Craig Stammen
You can tell the significance of any play in the game as much as anything by the reaction of the other players on the field. Steve Pearce was the runner at second on the final play Tuesday night, representing the tying run. Check him out on the replay (0:57), fist raised in triumph as he heads towards third base, confident he is watching a game-ending play of an entirely different nature.
Ian Desmond (@IanDesmond20) August 08, 2012
Meanwhile, Craig Stammen stood in the Nationals bullpen, just on the other side of the chain link fence from where Bernadina came crashing into the cutout. After the Shark came away with the ball, watch Stammen (at 0:11 and again at 1:03) jumping around, fists raised like a kid in the stands. Sure, Tyler Clippard’s primal scream and Jayson Werth’s bear hug speak volumes as well, but nothing matches Stammen’s unbridled joy from the ‘pen.
5. The Pennant Race
Oh yeah, the pennant race. As hot as the Nationals have been since the All-Star break, winning 14 of their last 18 games (including last night), the Atlanta Braves have kept pace. Washington held a four-game lead at the break, a mark that had not been matched until they were stymied by Cole Hamels and, some time later, Brett Wallace’s walk-off bid came to rest in Bernadina’s mitt. For the second time in four days, the Nationals have added to their division lead, and once again own the best record in baseball at 67-43. None of these things would be true if not for Bernadina’s catch.
Still want more on the Shark’s heroics? The Washington Post’s Dan Steinberg also did a great job of capturing some of the initial reactions – on the field, in the clubhouse and around the Twitter-sphere.
It seems that with each and every passing week of this 2012 season, the Washington Nationals are finding increasingly more dramatic and creative ways to win baseball games. There have been late-inning rallies, beginning on the season’s first two days at Wrigley Field. There have been walk-off wins of nearly every variety, from wild pitches (twice), to sacrifice flies, to heart-stopping, come-from-behind home runs. There have been victories of nearly every shade, coming in just about any way the mind can dream up. And then there was Monday night.
After carving out a 4-1 lead, the Nationals found themselves in extra innings against an Astros team that had won just four its last 34 games. Fortunately for Washington, that Houston squad had yet to win any of its nine extra-inning contests, and the Nats – no stranger to free baseball – were not about to become their first victim. But for all of the timely, clutch hits the team has put together lately and, really, all season long, this game turned on something entirely different.
We will make our best attempt to describe the play on paper, though it deserves to be seen, if you haven’t already watched it. After Roger Bernadina pulled a single through the hole between first and second base to open the top of the 11th, new Nationals catcher Kurt Suzuki bluffed at a bunt and took strike one. He squared again on the next pitch, popping the ball in the air in front of first base. Steve Pearce crashed from first, but the ball dropped in front of him, just as pitcher Wilton Lopez closed in to try to make a play of his own. Then, Pearce and Lopez literally crashed – into one another – with the ball glancing off the first baseman. Matt Downs came running in from third just as Pearce made a desperate effort to collect the ball and throw out Suzuki. Downs pulled up at the last second, flailing over Pearce as he dropped his elbow, the throw towards first instead sailing into foul ground and up the right field line.
Meanwhile, Bernadina raced from second to third, where Bo Porter held his hands up to stop the speedy outfielder, a prudent decision with none out in the inning. But the Shark had other plans. He blew right past Porter for the plate, and right fielder Brian Bogesevic’s throw, which seemed destined to make a close play at the plate, airmailed the catcher and went to the screen. When the dust settled, Bernadina had scored and Suzuki stood at third base.
The run would be all the Nationals would need to end a game they no doubt feel they should have won in much less time than the four hours and 15 minutes it took to complete.
Surely, they won’t be happy about the events that led up to the 11th inning on Monday, or that forced extra innings in the first place. The relief corps, which has been one of the most solid in baseball this season, suddenly became allergic to their own fastballs, falling behind hitters with off-speed pitches. After loading the bases in the eighth, Drew Storen escaped with the lead. When Tyler Clippard walked and hit a batter in the ninth, he did not. However, after allowing a game-tying double that left the winning run at third base with just one out, Clippard buckled down to strike out the next two batters, pushing the game to extra innings.
There was another bright spot from the relief corps’ performance, thanks to Craig Stammen. The same hurler who came up with 2.1 innings of clutch relief eight days prior in the Nationals maniacal, 11-10, multi-comeback game in Milwaukee, delivered again with 2.0 innings of hitless relief. No reliever in baseball has pitched at least two frames as often as Stammen, who did so for the 21st time on Monday. And so while the focus will remain, undoubtedly, on “what turned into a three-ring circus,” as Nationals radio man Charlie Slowes put it, the ultimate takeaway from Monday night is this: some way, some how, the Nationals just keep finding ways to win.
The Washington Nationals have made a name for themselves in the 2012 season by winning two different types of games. The first and more common type involves a healthy serving of solid starting pitching, a clutch piece of offense or two to snare the lead, and a lockdown performance by an ensemble bullpen. It is the kind of affair that the Nationals have found themselves involved in ever since their 2-1, Opening Day victory at Wrigley Field. But then there is that other kind of game, the nail-biting, nerve-fraying, mind-boggling variety that has made this season truly memorable.
This weekend’s matchups in Milwaukee provided one game from each mold. After splitting the first two of the four-game set with the Brewers, the Nationals sent hometown hero Jordan Zimmermann, originally from nearby Auburndale, Wisconsin, to make his first-ever start against the team he grew up supporting. The emerging ace delivered a sterling performance, allowing a single run on five hits, fanning six Milwaukee batters over six strong innings to extend his streak of throwing at least that many frames to 21 consecutive starts. In so doing, he lowered his ERA to the third-best mark in the National League at 2.28 and matched his career high with his eighth victory. He also improved to 4-0 with a 0.97 ERA in the month of July, during which he allowed just four earned runs and four walks while fanning 31 in 37.0 innings pitched.
Meanwhile, the Nationals rookies came through with huge contributions again, as Corey Brown opened the scoring with a solo shot and Tyler Moore added a two-run bomb to provide more than enough cushion in a 4-1 final. In all, it was a solid, shutdown performance that both the team and the coaching staff could be proud of.
Then, there was Sunday’s game.
In a battle of 2004 first-round picks, it was the less-heralded Mark Rogers who seemed poised to best All-Star Gio Gonzalez, as Milwaukee had forged a 3-1 lead through five fairly normal innings. Right about then, all convention went out the window. The Nationals led off the sixth with back-to-back doubles from Ryan Zimmerman and Moore, cutting the lead to one and putting the tying run in scoring position with nobody out. But they failed to plate that tying run, and Milwaukee responded by scoring twice in the bottom of the frame to push the lead to 5-2.
In the seventh, Washington looked poised to strike again, using singles from Brown and Steve Lombardozzi followed by a walk from Bryce Harper (all rookies!) to load the bases for Zimmerman, again with none out. But Cody Ransom turned a slick 5-3 double-play, limiting the Nats to just a single run once more. And again, the Brewers came right back for two more runs in the bottom of the frame, sitting pretty with a 7-3 advantage though seven frames.
This is, as they say, about the time when things got really interesting. With one out and a runner on first, Roger Bernadina flipped an opposite field home run into the bullpen in left-center field to cut the margin in half. Jesus Flores followed with a single, Brown with a double, and Lombardozzi with an RBI-groundout to cut the margin to one and put the tying run at third with two outs. One wild pitch later, and it was suddenly tied at 7-7. But the Brewers were not about to go quietly. With one out in the bottom of the eighth, Norichika Aoki and Carlos Gomez blasted back-to-back shots, reclaiming a two-run lead.
Ian Desmond (@IanDesmond20) July 29, 2012
For the fourth straight inning, the Nationals were looking uphill at a discouraging scoreline. And for the fourth straight inning, they mustered a rally. Mark DeRosa drew a one-out walk, bringing Michael Morse (featured in this homestand’s Inside Pitch… Pick one up at the ballpark!) to the plate as the potential game-tying run. After Milwaukee reliever John Axford forged ahead in the count, 1-2, his catcher set up low and inside for a fastball, anything to keep Morse from getting his arms extended. Axford missed his spot, leaving his pitch up and over the middle of the plate. Morse did not miss, sending the ball on a line over the right field wall, and once again, the game was tied.
Craig Stammen kept Milwaukee off the board in the bottom of the ninth to force extra innings, and neither team scored in the 10th inning. In the top of the 11th, Harper walked and Zimmerman singled, bringing Morse to bat with a chance to summon Beast Mode one more time. He delivered once again, pulling a double just inside the third-base bag to score both runners. Tyler Clippard would allow a solo shot to Corey Hart in the bottom of the frame, but shut the door in time to lock down the victory, with Morse himself gloving the final out on a foul pop in front of the Brewers dugout.
The games of this second variety, of the seemingly impossible string of back-and-forth momentum swings, of comebacks from the proverbial dead, seem to keep reaching more and more epic levels of absurdity at every pass. Sunday’s contest lacked only the walk-off hit, as it took place away from Nationals Park, but may have once again set the bar as the most dramatic of them all so far.
Perhaps most importantly, it capped a 6-1 road trip that kept the Nationals a full four games ahead of division rival Atlanta as the weekend came to a close. It also left them at 61-40, the first time the franchise has been this many games over .500 since its relocation to the Nation’s Capital. The Nats get a well-deserved off day on Monday, their only such breather in a 35-day stretch that sees them play 36 games, including seven more in a six-day stretch at home beginning on Tuesday. A word to the wise: take advantage of the day off yourself. You’re going to need every ounce of energy you’ve got left for the final 61 games of the regular season.
In the meantime, enjoy Morse’s theatrics one more time (as even Davey lets himself loose at the 1:04 mark) and both Bob Carpenter’s and Charlie Slowes’ calls of the action.
This is a story about a young, exciting team, built from the ground up through great drafts. It is a story about a dominating pitching staff helping lead the way through one of baseball’s toughest divisions. It is a tale of a team that endured injuries to its top outfielder, its franchise third baseman and its closer, yet found a way to keep winning games. It is about a franchise that has never enjoyed a season above .500, but suddenly found itself at 38-26 through its first 64 games, with a reason to believe it could look forward to exciting September – and possibly October – baseball.
This is a story about the 2008 Tampa Bay Rays.
If the themes sound familiar, well, they should. The parallels between this year’s Nationals team and that Rays squad that shocked the baseball world by winning 97 games and the American League East crown, eventually going all the way to the World Series, are astounding.
To start, there are number one overall picks – David Price and Stephen Strasburg – lighting up radar guns. While Price did not make his debut until late in the season, the staff was led by James Shields, Matt Garza and Scott Kazmir, all 26 or younger. Similarly, the Nationals have their rotation of Gio Gonzalez, Jordan Zimmermann and Edwin Jackson behind Strasburg, with Jackson being the elder statesman at 28. Oh, by the way, where do you suppose Jackson was four years ago, when he was just 24? Sharing the Rays team lead in wins with Shields, as the fourth member of that 2008 rotation.
Tampa Bay also turned in by far the best year the franchise had ever seen without a single player, starter or reserve, batting over .300, finishing 13th out of 14 in the American League in hitting. But great pitching can help make up for a lot. Aside from the aforementioned starters, they also had great bullpen pitching, led by Grant Balfour (6-2, 1.54 in 51 appearances), Chad Bradford (1-0, 1.42 in 21 appearances) and J.P. Howell (6-1, 2.22 in 64 appearances). As we discussed when the homestand began, the trio of Sean Burnett, Tyler Clippard and Craig Stammen have combined for a 1.65 ERA over their first 87.2 innings pitched this season, holding down the fort until closer Drew Storen returns.
The Rays survived the gauntlet of the AL East with just one 30-home run hitter, first baseman Carlos Pena, who hit 31. The Nationals top power threat so far has been first baseman Adam LaRoche, who is quietly having a terrific comeback season after spending most of last year on the Disabled List. LaRoche launched his 12th home run of the season Sunday, putting him right on pace for 30 this season.
Then there are the scintillating rookies – Evan Longoria and Bryce Harper – that have energized the fan base, and given each franchise a face recognized around the baseball world. Buoyed by that national support, the Rays had three players selected to the All-Star Game that July, the most the franchise had ever sent to the Mid-summer Classic. The third and final to go (joining Kazmir and catcher Dioner Navarro) was Longoria, who won the MLB Final Vote campaign. With Strasburg and Gonzalez seeming like strong candidates from the rotation, might Final Vote history repeat itself, giving Washington three All-Stars in 2012?
If the Nationals needed any consolation after one of the toughest weekends of the season, they need only look into the opposing dugout, at a franchise that has become the model after which many wish they could mold themselves. The Rays have averaged 92 wins each of the last four years, led by that core of young players and a strong pitching staff. If they can do it, why can’t the Nationals?
So, is this a story about the 2008 Tampa Bay Rays, or is it a story about the 2012 Washington Nationals?
Craig Stammen’s season was the definition of erratic–he moved from the Nationals’ starting rotation to the Minors then back to the Majors and finally to the bullpen. His games were nearly as unstable as his place on the pitching staff. At times, he looked commanding, while other times, he lost control. He did throw the ball harder this season, but a mildly faster fastball that averages around 90 mph and a tighter curveball, don’t always translate to immediate success.
Stammen started the season in rocky fashion, managing just 6.1 innings combined in his first two starts while giving up 11 runs and striking out just one. He immediately improved in his next two starts, this time going a combined 15.0 innings while giving up just five total runs and striking out eight.
Stammen was optioned to Triple-A ball to make room on the active roster for Stephen Strasburg on June 7. He went 2-0 with a 2.25 ERA in three solid starts for the Syracuse Chiefs and returned to the Nationals starting rotation later that month. The move would last a little over a month, during which time Stammen went 3-2 in seven inconsistent games–the type that have defined his short career as a starting pitcher. In Stammen’s return on June 29 against the Braves, he pitched 7.1 innings of two-run ball, holding opposing batters to a .192 average to earn the win. But in his very next start on July 4, Stammen lasted only 3.1 innings before giving up seven earned runs, walking three and walking away with the loss.
Stammen was again taken out of the starting rotation on August 8, but this time he was moved to the bullpen, where he would remain, with moderate success, for the rest of the season. Unlike most starting pitchers, Stammen did not publically grumble about the move, saying, “I’m just Craig, a little old 12th rounder. It’ll be alright. Whatever they want me to do is what I’ll do. Start, come out of the bullpen, clean the balls off.” He previously worked as a reliever in the Minors and left the University of Dayton as the all-time saves leader. “It doesn’t really bother me. It’s not like it’s a demotion,” Stammen said of the move.
This is only Stammen’s second season as a Major League pitcher, so it is way too early to give up on him due to his lack of consistency. The Nationals do have use for him, but the question is, where? Will he pan out as a starter next year? Most likely, he will prove more valuable as a long reliever who may get called on to start from time to time if a vacancy in the rotation arises.
Craig Stammen is back in the Majors and he will be asked to stop the Nats five game losing streak.
The Nationals recalled Stammen from Triple-A Syracuse and placed right-handed pitcher Tyler Walker on the 15-day disabled list, retroactive to June 20, with a right shoulder AC joint sprain.
Stammen, who will get the starting nod tonight at Atlanta, went 2-0 with a 2.25 ERA during a three-start International League stint with the Chiefs.
The 26 year-old Stammen began the season with the Nationals and went 1-2 with a 5.43 ERA in 12 starts before being optioned to Syracuse following his June 6 start vs. Cincinnati. Five of Stammen’s 12 assignments rendered quality starts, but the Nationals went just 1-4 in those contests.
Stammen is 5-9 with a 5.23 ERA in 31 career starts with Washington spanning two seasons (2009-present).
The 34-year-old Walker is 1-0 with one hold and a 3.57 ERA in 24 games for the Nationals.
