Sam Antonacci is a left fielder for the Chicago White Sox. In 2026 he hit 8 home runs and knocked in 48 RBIs, notching 133 hits across 557 plate appearances in 139 games. His batting average was .277, 13.6% higher than the league average of .244. He reached base at a .370 clip and slugged .396, for an OPS of .766, 6.5% higher than the league mark of .719 — 5th of 14 on his team, and 116th of 465 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 4.5% of them and made contact on 85.3% of his swings. Adjusted for his ballpark and league, his 122 wRC+ puts his offence 22% above average. That comes to 3.2 dbWAR — +13.5 runs with the bat, +0.5 for the ballpark, -0.3 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.
