2. Kohl Stewart RHP: In 2013, the Twins plucked Stewart with the fourth overall pick in the draft. The potential to be a major league ace is there, and Stewart flashed that ability at Cedar Rapids. Just his second year of focusing completely on baseball, Stewart will need to continue to learn to command the strikezone, and how to utilize both his mid-90s fastball along with his breaking pitches. After seeing his 2014 season come to an end due to shoulder issues, the hope is for a clean bill of health and being able to translate his success with Single-A Fort Myers.
