Jack O'Connor: 3B/1B, (2025) Xaverian Brothers, MA. 5-foot-11, 160-pound lean athletic frame. Athletic and capable at the plate, O'connor had a max exit velocity of 82 mph. (60.9 mph bat speed average). (23.5 mph hand speed average). Began in a balanced athletic stance with a wrapping load, then used a small stride. Bat speed was developing, uses a flat long swing plane and level finish. Had loud contact and found some barrels. Line drive approach. Capable in the infield, his best throw was registered at 63 mph; showed developing consistent feet, a natural exchange, and developing soft hands. Movements laterally were developing and he fields the ball out front. Had a high ¾ slot and consistent accuracy to the bag.
