Following Baseball America’s ranking of the Top 10 Nationals prospects earlier this week, we turn our attention to a prospect whose journey has largely escaped the spotlight to this point. Rob Wort, the Nationals 30th-round draft pick in 2009, burst onto the scene this past season with the highest strikeout rate in all of Minor League Baseball.

Featuring a power fastball/slider combo, the lean, 6-2, right-handed reliever wrapped up his second full season at High-A Potomac with eye-popping numbers. In 56.2 innings, Wort notched 95 strikeouts against just 19 walks, earning 13 saves for the P-Nats and a spot on the Carolina League All-Star Team.

Wort’s performance was even more impressive in comparison with his peers. Among the more than 2,300 Minor League pitchers to complete at least 40.0 innings in 2012, Wort ranked first in both strikeouts per nine innings (15.1) and strikeout percentage (41.3). The only two professional pitchers with more dominant strikeout numbers than Wort were Atlanta’s Craig Kimbrel and Cincinnati’s Aroldis Chapman, both of whom had historically great seasons in the Major Leagues.

Chris Michalak, Potomac’s pitching coach and a former Major Leaguer himself, has overseen Wort’s development at two Minor League stops. Before his 2012 breakout season, Wort was at his best in 2010 at Low-A Hagerstown – with Michalak coaching him there as well – where he went 5-0 with a 2.08 ERA and 53 strikeouts in 43.1 innings. After Wort suffered through a lackluster 2011 campaign, the newly promoted Michalak guided a change in approach for the 23-year-old hurler.

“The biggest thing (prior to 2012) was that Rob was able to get by with his fastball and a little different arm angle,” Michalak said. “This year we worked on two things: using his backside and legs to leverage the ball and get later movement on his pitches, and developing his slider. His slider became a legitimate out pitch down and away to right-handed hitters.”

Opposing righties stood little chance against Wort this past season, batting a meager .174/.243/.265 and striking out an astonishing 69 times in 144 plate appearances. Lefties fared only marginally better, hitting at a .247/.349/.392 clip with 26 punchouts in 86 trips to the plate. This was a huge improvement for Wort, after lefties batted .354/.475/.625 and struck out just eight times in 64 plate appearances against him in 2011.

Wort notched the highest K rate in the Minor Leagues in 2012.

Michalak explained the specific changes that led to Wort’s dramatic improvement against batters from the left side of the plate.

“We wanted to give him more weapons against left-handed hitters,” Michalak said. “Rob tried out a new two-seam fastball and a change-up, which added a couple of wrinkles to what he was doing before. Those became effective pitches for him.”

Should Wort continue his development and eventually earn his way onto the Nationals roster, he would join Toronto left-hander Mark Buehrle as the second Major League player to attend both Francis Howell North High School (St. Charles, Mo.) and Jefferson College (Hillsboro, Mo.). Buehrle was also a late round pick, going to the Chicago White Sox in the 38th round in 1998. Michalak, who was a 12th-round selection out of college and fought his way to the big leagues for the first time at age 27, thinks his pupil has a good shot.

“This year really opened up (Rob’s) eyes a little bit, gave him confidence he could get there,” Michalak said.  “If he continues to make adjustments throughout each season, throughout his career, and he’s not afraid to take those adjustments into the game, I don’t see why he doesn’t have a chance.”
