just wild guesses
Hermida - will slump at some point and need to make adjustments in his first full season, will finish nicely overall for a rookie .. 265, 12 hr, 19 sb, 70 runs, 59 rbi
Cain - up and down struggles.. 4.30 era which is decent, 1.40 whip will hurt, but will have some really good hot streaks
Liriano - slow start, will finish with great season out of the bullpen, with low whip and high k/9..
Baker - has most experience out of the 4 .. i think he can easily match what Danny Haren and Joe Blanton did this year.. but with more k's ..
sleeper pick ---> paul malholm, watch out
