TJ Rumfield is a first baseman for the Colorado Rockies. In 2026 he hit 16 home runs and knocked in 73 RBIs, notching 164 hits across 631 plate appearances in 155 games. His batting average was .300, 22.9% higher than the league average of .244. He reached base at a .390 clip and slugged .453, for an OPS of .843, 17.3% higher than the league mark of .719 — the best on his team, and 29th of 465 among MLB batters with 100+ plate appearances. He averaged 84.3 mph off the bat, hit 28.0% of balls in play at 95 mph or better, barrelled 4.3% of them and made contact on 81.2% of his swings. Adjusted for his ballpark and league, his 134 wRC+ puts his offence 34% above average. That comes to 4.2 dbWAR — +30.0 runs with the bat, -1.7 for the ballpark, -1.1 on the bases, +1.8 on double plays, -8.3 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.

A barrel is a batted ball whose exit velocity and launch angle have historically produced at least a .500 average and 1.500 slugging — 98 mph within 26–30°, widening to 8–50° by 116 mph. Reconstructed from Statcast's published anchor points, which reproduces them exactly; the interior is within a degree. Sweet spot (8–32°) is an exact definition.

How these are computed

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.
