Sam Antonacci

School: Coastal Carolina
Commit/Drafted: Never Drafted
Age at Draft: 21.5

Antonacci ranked as the No. 316 player in the 2023 class after a monster season with Heartland (Ill.) JC. Despite drawing draft interest at the time, Antonacci went to Coastal Carolina for his first taste of D-I baseball where he continued to show the same high average and excellent on-base skills he showed at the junior college level. The 6-foot, 193-pound third baseman was hitting .406/.571/.534 with a 19.6% walk rate through his first 37 games and rarely expands the zone or swings and misses in general. His 93% in-zone contact rate is a standout metric, but he might be reliant on a savvy eye and excellent contact skills to drive an offensive profile that lacks power. To that end, Antonacci might be better served at second base instead of a corner in pro ball, where he can play up the middle and have less pressure to hit for power. He previously played shortstop, but has been Coastal’s everyday third baseman in 2024. He could fit as a day two draft prospect for teams that prioritize his bat-to-ball skills and swing decisions.
