Marcus Semien is a second baseman for the New York Mets. In 2026 he hit 14 home runs and knocked in 41 RBIs, notching 76 hits across 392 plate appearances in 100 games. His batting average was .213, 12.4% lower than the league average of .244. He reached base at a .274 clip and slugged .362, for an OPS of .636, 11.6% lower than the league mark of .719 — 12th of 15 on his team, and 327th of 417 among MLB batters with 100+ plate appearances. He averaged 86.2 mph off the bat, hit 36.3% of balls in play at 95 mph or better, barrelled 7.0% of them and made contact on 75.7% of his swings. Adjusted for his ballpark and league, his 73 wRC+ puts his offence 27% below average. That comes to 0.3 dbWAR — -12.0 runs with the bat, +0.3 on the bases, +1.6 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.
