Junior Perez is a left fielder for the Chicago White Sox. In 2026 he hit 3 home runs and knocked in 6 RBIs, notching 6 hits across 36 plate appearances in 16 games. His batting average was .171, 29.6% lower than the league average of .244. He reached base at a .194 clip and slugged .429, for an OPS of .623, 13.4% lower than the league mark of .719. He averaged 91.0 mph off the bat, hit 52.4% of balls in play at 95 mph or better, barrelled 14.3% of them and made contact on 60.6% of his swings. Adjusted for his ballpark and league, his 62 wRC+ puts his offence 38% below average. That comes to -0.1 dbWAR — -1.7 runs with the bat, -0.4 on the bases, -0.3 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.

Head to head
Put Junior Perez beside up to three others.
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.
