Each week, we will recap the performances of the eight members of the Nationals organization participating in the Arizona Fall League, a “finishing school” for top prospects. 

The eight Nationals players are members of the Mesa Solar Sox, which is comprised of young stars from the Nationals, Angels, Athletics, Cubs and Tigers farm systems. The Solar Sox will battle the Glendale Desert Dogs, Peoria Javelinas, Salt River Rafters, Scottsdale Scorpions and Surprise Saguaros during the six-week season, with each team made up of players from five MLB organizations.


Nationals Director of Player Development Doug Harris sat down with Curly W Live to discuss the progress of left-handers Matt Purke and Sammy Solis, two of the top hurlers in the Arizona Fall League. Purke, a 2011 third-round pick, and Solis, a 2010 second round selection, completed their regular seasons with the High-A Potomac Nationals. Here are the highlights from that Q&A:

Curly W Live: Where are Matt Purke and Sammy Solis in their overall development?

Doug Harris: Both finished their regular seasons really well. Even though their innings were limited, their volume was fairly significant because they were doing a lot of work on their arms prior to them actually getting into a game. They had a nice break after the playoff run with Potomac, which freshened them up, so now they’re where they would be if they were coming down the home stretch of a regular season.

Matthew’s command is a little more crisp than it was during the regular season, which enables him to utilize his secondary stuff. You’re seeing some strikeouts and his walks are down. Sammy’s stuff has been really good out there. He’s gotten ahead of hitters very quickly, but he’s walked a few because he’s gone to his secondary stuff a little more than he’s needed to.

CWL: Are they both fully back on track from previous setbacks?

Harris: First and foremost, they have health. Both are very talented young men and have worked very hard to get themselves back to this point. Matthew, in particular, battled some ups and downs early on. He had a little clean-up that has enabled him to not look back and be more of the pitcher that we saw (in college). Sammy was moving really well through the system, had the Tommy John surgery, and now he’s right back on track.

CWL: They have put up excellent numbers in the Arizona Fall League. How much of an indicator are the statistics down there?

Harris: I think they’re somewhat of an indicator, but I don’t think they’re the gospel. With the Arizona Fall League, you look at each hitter day-to-day and each pitcher outing-to-outing. It’s somewhat of a scripted league, so you have to dissect things day-to-day a little more than you would in the regular season.

Matthew’s good fastball command has enabled him to get to his secondary stuff, which is why you’re seeing low hits-to-innings-pitched from him (three hits in 12 innings as of October 28).

CWL: What type of pitches are they throwing and how is their velocity?

Harris: Both have a very similar mix: a fastball, curveball and change. Sammy’s fastball is a tick more firm than Matthew’s at this point. Sammy, prior to Tommy John, was up to 96 and we’ve seen comparable velocity from him. During the regular season, Matthew was up to 94, but they both pitch in the 90-92 range. Both have good movement on their fastballs, and they’re both still developing their breaking ball consistency. Sammy’s change-up is ahead right now. Matthew is still learning how to throw it, when to throw it and developing trust in throwing it.

CWL: Do you have any goals for them for the rest of the Arizona Fall League season as they head into Spring Training?

Harris: The first thing is maintaining their health. They’re taking the ball every fifth day and they have a five-inning cap. After an abbreviated season, they’re increasing their volume, which will really allow us to expand their innings next year. That’s a critical thing for us. They’ll continue to work on fastball command and the quality of their secondary stuff. The most important thing is having them (arrive at Spring Training) healthy and ready to go into a strong 2014.


In addition to earning rave reviews from Harris, Purke is beginning to pick up accolades for his work on the mound. The left-hander earned Arizona Fall League Pitcher of the Week honors on Tuesday, following his five innings of scoreless, one-hit baseball against Scottsdale on October 23.

Purke will take the hill Tuesday evening in prime time, when the Mesa Solar Sox travel to Salt River to take on the Rafters.


Center field prospect Brian Goodwin will represent the Nationals in this Saturday’s Arizona Fall League Fall Stars Game, the league announced Monday. Goodwin, who will celebrate his 23rd birthday the day of the game, has compiled a .304 batting average with five runs scored and three RBI in 11 games with the Mesa Solar Sox this fall.

This will mark Goodwin’s second consecutive appearance in the Fall Stars contest, formerly known as the Rising Stars Game. MLB Network will broadcast the exhibition live at 8 p.m. ET on Saturday from Surprise, Arizona.
