Isiah Kiner-Falefa is a second baseman for the Boston Red Sox. In 2026 he hit 2 home runs and knocked in 16 RBIs, notching 39 hits across 183 plate appearances in 59 games. His batting average was .242, 0.7% lower than the league average of .244. He reached base at a .322 clip and slugged .311, for an OPS of .633, 12.0% lower than the league mark of .719 — 12th of 16 on his team, and 357th of 465 among MLB batters with 100+ plate appearances. He averaged 80.6 mph off the bat, hit 25.9% of balls in play at 95 mph or better, barrelled 2.2% of them and made contact on 82.3% of his swings. Adjusted for his ballpark and league, his 81 wRC+ puts his offence 19% below average. That comes to 0.5 dbWAR — -3.9 runs with the bat, -0.2 for the ballpark, +0.5 on the bases, +0.7 on double plays, +1.8 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.
