10/23/2011 - College PREP - Atlanta, GA Devin is a tall LHP that will graduate in 2013. Arm action is quick / loose and he has arm strength as indicated by top velocity of 84 mph. He has some mechanical flaws in his delivery that needs to be corrected to allow his arm to work at it full potential. Fastball shows a range of 81-84 mph. Changeup is best off speed pitch showing decent feel with arm side run. Breaking ball displays 2/8 shape with gradual break but needs to find a consistent release while staying on top of pitch. He will pitch in on right handed hitters, but needs to work on improving command / control with all his pitches. With 2 years to further develop, Vainer has a ton of potential and will catch the eyes of the collegiate coaches as he continues to improve.
