A.J. DeMastrie is a steady, contact-first catcher for Dartmouth with impact upside
In the 2026 season, junior catcher A.J. DeMastrie has been a lineup anchor for Dartmouth, batting .265 with a .693 OPS in 23 games while adding 22 hits, 10 RBI and a strong .349 on-base percentage[1]. He fits the profile of a dependable, defense-minded backstop: Dartmouth’s roster notes show he has already posted a .992 fielding percentage in a previous season and has repeatedly delivered multi-hit games and timely RBI[2]. The value here is consistency, catchability, and enough offensive competence to stay in the middle of a college lineup[1][2].
