Sam Antonacci is a left fielder for the Chicago White Sox. In 2026 he hit 8 home runs and knocked in 34 RBIs, notching 91 hits across 386 plate appearances in 96 games. His batting average was .273, 12.2% higher than the league average of .244. He reached base at a .366 clip and slugged .402, for an OPS of .768, 6.7% higher than the league mark of .719 — 4th of 14 on his team, and 112th of 417 among MLB batters with 100+ plate appearances. He averaged 87.0 mph off the bat, hit 36.1% of balls in play at 95 mph or better and made contact on 85.4% of his swings. Adjusted for his ballpark and league, his 123 wRC+ puts his offence 23% above average. That comes to 1.8 dbWAR — +9.4 runs with the bat, -0.7 on the bases, -3.4 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.

wOBA uses linear weights measured from this season's own play-by-play rather than published constants, and wRC+ is park-adjusted against that same league. dbWAR is our own open implementation — not fWAR or bWAR — and the full derivation, including its simplifications, is on the methodology page.
