ALTOONA, Pa. - There isn't another prospect in the Pirates system with nearly as much hype as Mitch Keller. He has vaulted himself to the top of nearly every prospect list around, and he is being recognized as one of the most promising right-handed pitchers in the minors.
The funny part is that you could have easily replaced Keller's name with Tyler Glasnow only a few years ago -- both right-handed pitchers with dominating fastballs and curveballs. Both needed to commit to improving their changeup to be able to continue their rise through the minors.
Glasnow's need for a changeup was much more important.
