Andrew Cashner made is major league debut for the Cubs in 2010 and his performance was less than stellar. He walked a high number of batters and gave up eight home runs in just 54 1/3 innings. He only allowed three home runs in his three seasons in the minors. Andrew also showed improving control as he progressed through the Cubs system, so there is hope for the first round pick improving in the future.
One trait Cashman showed which I believe will benefit him in his career is a rising pitch:
During the playoffs, I discussed how Matt's movement helps keep his home run rate low despite a high percentage of fly balls. Andrew actually did a good job of keeping the ball on the ground in 2010, with 50% of the balls in play against him grounders. As his career progresses, I'm curious to see if his rising pitches turn most of his fly balls into outs, or if outbound windy days at Wrigley field take their toll.
