Sam McWilliams

McWilliams is one of the prime pop-up arms in the country and has been something of an enigma this spring because his stuff can differ significantly start to start. He worked at 83-86 mph last fall, touching 88. At his best this spring, he sits in the low 90s while touching 94 mph. Other days he can sit 84-86 and even drop as low as 83. His breaking ball frequently plays as below-average, but shows enough spin to project close to average. He has some feel for a changeup that flashes average. The 6-foot-7, 190-pound McWilliams offers plenty of room for projection, and some of his inconsistency comes from a delivery that will likely be altered in pro ball. The Tennessee Tech commit's lack of history, projectable body and inconsistent stuff make him a wild card on draft day.
