Zach Stewart: A 2008 third-round pick out of Texas Tech, Stewart has had no problems dominating hitters in professional baseball. His up-and-down college career included stints in both the starting rotation and the bullpen. His pro career has been no different; Stewart spent his debut season in the ‘pen before moving to the rotation in 2009. He made seven starts in both high-A and double-A before moving back to the bullpen with a recent promotion to triple-A. That moves pretty much signifies that the Cincinnati organization views Stewart, 22, as a prospect that can help the club in the not-too-distant future. In double-A, the right-hander allowed just 29 hits in 37 innings of work while posting rates of 2.43 BB/9 and 7.54 K/9. He also does a nice job of keeping balls-in-play on the ground.
