Isaac Collins is a left fielder for the Kansas City Royals. In 2026 he hit 6 home runs and knocked in 40 RBIs, notching 94 hits across 519 plate appearances in 143 games. His batting average was .213, 12.8% lower than the league average of .244. He reached base at a .320 clip and slugged .321, for an OPS of .641, 10.8% lower than the league mark of .719 — 12th of 15 on his team, and 343rd of 465 among MLB batters with 100+ plate appearances. He averaged 87.1 mph off the bat, hit 39.3% of balls in play at 95 mph or better, barrelled 4.6% of them and made contact on 78.2% of his swings. Adjusted for his ballpark and league, his 81 wRC+ puts his offence 19% below average. That comes to -0.1 dbWAR — -9.2 runs with the bat, -1.5 for the ballpark, -1.2 on the bases, -0.6 on double plays, -4.2 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.

Contact rate78.2%

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.
