Matheson still has plenty of room to mature physically with a young face and a long-limbed, wiry frame at 6-foot, 150-pounds. The right-hander has natural arm speed that provides for life on his fastball at 85-87 (up to 89 earlier this fall). His slider varies in shape at times depending on when he separates his hands, but when his delivery is synced up, the pitch can be sharp at 72-75 mph. The changeup is already a quality pitch at 80 mph with arm side fade. Moving forward, Matheson has a chance to make even more jumps as he matures physically and starts to sync up his delivery.

Matheson has a wiry, long-limbed frame at 6-foot, 150-pounds. The right-hander has a fast arm that produced the best velocity of the day at 89 mph, sitting 87-88. Curveball was 72-76, and he throws a plus changeup with arm side depth at 78-83 mph. Tended to miss high arm side, but he was able to make a couple of adjustments during the session to get the ball down in the zone. Recruiters will need to make sure they follow Matheson closely as there is already hand speed with some feel for three pitches.
