Sam Antonacci is a left fielder for the Chicago White Sox. So far in 2026 he has hit 8 home runs and knocked in 48 RBIs, notching 130 hits across 549 plate appearances in 137 games. His batting average is .275, 12.7% higher than the league average of .244. He reached base at a .368 clip and slugged .393, for an OPS of .761, 6.0% higher than the league mark of .719 — 6th of 14 on his team, and 129th of 462 among MLB batters with 100+ plate appearances. He averaged 87.1 mph off the bat, hit 33.7% of balls in play at 95 mph or better, barrelled 4.6% of them and made contact on 85.3% of his swings. Adjusted for his ballpark and league, his 121 wRC+ puts his offence 21% above average. That comes to 3.0 dbWAR — +12.5 runs with the bat, +0.5 for the ballpark, -0.4 on the bases, +2.1 on double plays, -2.7 for the position he plays, against replacement level. It includes no fielding: defensive runs are proprietary and are not estimated here, so the figure credits playing a demanding position but not playing it well.
