The Nationals call up a pitching prospect to fill in for the injured Ross Detwiler.
The Situation: Following a breakout 2012 season, Karns seemed destined for another full season in the minor leagues blocked by a loaded Washington rotation. With just one injury, though, things can change, and they changed to Karns’ benefit when Ross Detwiler injured his oblique, creating a need for another starter.
Background: After battling inconsistency at North Carolina State and Texas Tech, Karns’ draft stock plummeted in 2009, as he was routinely touched up throughout the spring. He was finally popped in the 12th round by the Nationals and signed for $225,000. Almost immediately after signing, Karns came up lame with a torn labrum and missed the remainder of the 2009 season and all of 2010. Back on the hill in 2011, Karns posted a solid 3.44 ERA in eight starts for the New York-Penn League’s Auburn Doubledays. His breakout came in 2012 with good health and monster showings at both Low-A and High-A. On the season, he recorded a 2.17 ERA in 116 innings with just 70 hits allowed, 47 walks, and 148 punchouts. Karns has handled the jump to Double-A reasonably well this season, pitching to a 4.60 ERA in nine starts, allowing less than a hit per inning, and fanning 11 batters per nine.
