Sean
McNair

Uncommitted, currently ranked No. 149 in the state. Compact 5-foot-8, 175-pound frame. Started on the mound for the Warriors in the 4A Deerfield Regional Semifinal, tossing five shutout innings with only three hits allowed. The left-hander was an athletic mover on the mound, working downhill with intent, with a quick ¾ arm slot that hid the ball well. Looked to be a fierce competitor on the mound, wanting the ball in big situations and working out of multiple jams. Displayed confidence in his three pitch mix, producing swings and misses throughout the outing to finish with seven strikeouts. His fastball sat 86-89 mph early on, settling into 85-88 mph with late arm-side run. He also flashed a deceptive changeup at 79-82 mph that played with heavy armside sink, and a sharp horizontal slider at 74-77 mph. An overall impressive outing from the still uncommitted junior, who continues to make a name for himself as a left-handed arm to follow.
