GLENDALE, Ariz. - Mitch Keller was drafted in the second round of the 2014 draft. At the time, he wasn't seen as a future top of the rotation option, at least not any more than your normal projectable pitcher out of high school. He came into pro ball and quickly impressed, but clearly had things to work on with his control, and didn't have top velocity yet.
Keller added that two years later in his breakout season in West Virginia. The velocity increased to the upper 90s, and the control was straightened out after an adjustment to keep his glove arm steady.
