Born in Lakewood, Ohio but blessed with a name that really belongs in Texas, righthander Stetson Allie is one of the hottest teenaged arms in baseball. He played third base a great deal in high school, too, and is an average defender and slightly above-average hitter from that position, but most scouts agree his future is on the mound, where his signature is heat, heat and more heat. He can already bring a near-99mph fastball to the plate with an easy, repeatable delivery and mix in a filthy slider whenever he likes.

Command is a big issue, as is his ability to deal with hitters late in games, so many see him as an ideal closer. Whether Pittsburgh is the right place to develop and polish the young pitcher is a question worth considering, but if he comes along as expected he should provide the third arm in a potentially dominant rotation by the middle of the decade. Worst case, he could be closing games in Pittsburgh by the end of 2013.
