05/26/2014 - College PREP - Jupiter, FL Mack is a solid, athletic, 2-way player who projects best on the mound. Mack has a loose / clean arm action, good life on his pitches, and he gets good extension. He stands over the rubber well, has a proper stride, and finishes in a good position out front. Continuing to add arm strength and command will raise Mack/s stock on the mound. At 1st base, Mack has good body control, efficient footwork, and sure hands. He takes good angles to the ball, fields cleanly, and throws with accuracy and carry to his target. Quickening his feet and release will result in higher defensive grades. At the plate, Mack has good balance, an activated load, and solid bat speed. He has pop in his bat and gets good extension through the ball. Hitting will improve if Mack can through his hands more toward the ball and avoid spinning off.
