Brett Wallach, 21, Single-A: Wallach is a solid third round pick from the 2009 draft having himself another good year for Class-A. He is 6-0 in 17 starts this season with a 3.42 ERA and 92 strike outs to 43 walks. Hitters are hitting just .230 against him. He has an above average fastball, plus slider and change, and has great mound presence. I believe the Cubs will test him at Double-A Tennessee at some point this season, and that is where he will probably remain for the foreseeable future.
Kyle Smit, 22, Double-A: Smit was working in relief in Single-A until his recent promotion, posting a 2.49 ERA in 34 appearances. He struck out 46 to just 10 walks, but only held hitters to a .262 average. The Cubs may keep him in Double-A and see if his hot start can continue. Otherwise, the fifth-round pick from the 2006 draft has been a disappointment.
