Mac Williamson is a 2008 RHP with a 6'4'', 200 lb. frame from Wake Forest, NC who attends Wake Forest - Rolesville HS. He has a big, broad shouldered build with some present strength and more to come. Williamson was a primary catcher until this spring but has made a full-time conversion to pitcher, although he still has college level catching tools. Williamson's arm strength and pitching ability is his future. He throws from a slow paced, deliberate delivery with a long loose arm and little effort on release. Williamson's fastball was consistently 90-92 mph with hard arm side run at times. He showed a feel for both a downer curveball and a change up and both pitches could really develop well as Williamson gets more experience on the mound. Williamson projects very well and it wouldn't be surprising to see him move his velocity up a bit and improve the sharpness on his breaking ball in the near future.
