Anthony Seigler is a second baseman for the Boston Red Sox. So far in 2026 he has hit 3 home runs and knocked in 13 RBIs, notching 37 hits across 173 plate appearances in 48 games. His batting average is .247, 1.1% higher than the league average of .244. He reached base at a .327 clip and slugged .400, for an OPS of .727, 1.2% higher than the league mark of .719 — 7th of 16 on his team, and 176th of 462 among MLB batters with 100+ plate appearances. He averaged 86.1 mph off the bat, hit 34.4% of balls in play at 95 mph or better, barrelled 4.8% of them and made contact on 77.5% of his swings. Adjusted for his ballpark and league, his 102 wRC+ puts his offence 2% above average. That comes to 0.8 dbWAR — +0.7 runs with the bat, -0.1 for the ballpark, +0.2 on the bases, +0.2 on double plays, +1.3 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.

Anthony Seigler's arsenal by usage. Velocity is average release speed in mph, spin in rpm, and whiff rate is misses per swing — the cleanest single measure of whether a pitch beats hitters. BAA and OPS are what hitters did against each pitch, credited to the one that ended the plate appearance, and are left blank under 15 at-bats.

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.
