Willi Castro is a second baseman for the Colorado Rockies. In 2026 he hit 13 home runs and knocked in 48 RBIs, notching 94 hits across 395 plate appearances in 99 games. His batting average was .263, 8.1% higher than the league average of .244. He reached base at a .332 clip and slugged .426, for an OPS of .757, 5.3% higher than the league mark of .719 — 7th of 14 on his team, and 121st of 417 among MLB batters with 100+ plate appearances. He averaged 86.8 mph off the bat, hit 39.8% of balls in play at 95 mph or better and made contact on 69.3% of his swings. Adjusted for his ballpark and league, his 108 wRC+ puts his offence 8% above average. That comes to 1.9 dbWAR — +5.5 runs with the bat, -0.8 on the bases, +1.1 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.
