Aaron Wilkerson

Wilkerson found little success with Triple-A Colorado Springs after being acquired by the Brewers in 2016, so the team decided to assign him to the Double-A ranks for the entire 2017 season. The move seemed to work, as he was steady over 24 starts and showed enough to make his major-league debut last September. Wilkerson has averaged over a strikeout per inning in his minor-league career, but he is not a hard thrower -- he averaged just 89.7 mph on his fastball over his three appearances with the big club -- so his fantasy upside is limited. He could find himself in the conversation for a rotation spot this spring, but given his lack of velocity and with just 20 career Triple-A outings under his belt, he will likely find himself on the outside looking in come Opening Day.
