Mason Sebastyanski: SS/OF, (2026) Bartlett, MA. 6-foot, 177-pound athletic projectable frame. Projectable at the plate, the hitter recorded an exit velocity of 87 mph. (64.2 mph bat speed average). (19.0 mph hand speed average). Began in an open narrow stance with a controlled load, then used a closed small stride. Bat speed is developing, has a loose swing plane and good extension on his finish. He created loud contact and found multiple barrels. Gap to gap approach. Capable while in the infield, registered his best throw across the diamond at 79 mph; had a natural exchange, developing hands, and developing consistent footwork. Fields the ball out front, movements laterally were developing. Had consistent accuracy to the bag with a high ¾ slot. Recorded a time of 8.1 in the 60-yard dash.  (Max spin 1790; Avg 1705).
