Haley, 23, was selected in the second round of the 2008 draft. The Texas native posted solid ERA numbers and big strikeout totals in 2011-12 despite a poor walk rate. His command worsened in 2013, however, as he walked 39 batters in 44 frames. Haley still managed to strike out 46 batters in that time and keep his ERA at 4.70, but command looks to be a persistent problem for him. In 323 minor league innings, Haley has a 299-to-241 K/BB ratio to go along with 42 hit batters and 58 wild pitches.
