5. Kohl Stewart, RHP
Now focused fully on baseball, Stewart is still coming into his own after being taken by the Twins 4th overall in 2013. He pitched well in Cedar Rapids last season, and has been dominant in his time as a pro. Shoulder issues flared up last season, but appear to be behind him. If he can continue to refine his pitching technique as a whole, the expectation of a front of the rotation starter should stick.
