Matt Wallner is a right fielder for the Minnesota Twins. In 2026 he hit 4 home runs and knocked in 10 RBIs, notching 20 hits across 135 plate appearances in 34 games. His batting average was .167, 31.6% lower than the league average of .244. He reached base at a .259 clip and slugged .292, for an OPS of .551, 23.4% lower than the league mark of .719 — the worst on his team, and 399th of 417 among MLB batters with 100+ plate appearances. He averaged 88.4 mph off the bat, hit 40.3% of balls in play at 95 mph or better, barrelled 10.4% of them and made contact on 56.0% of his swings. Adjusted for his ballpark and league, his 57 wRC+ puts his offence 43% below average. That comes to -0.5 dbWAR — -7.1 runs with the bat, -0.6 on the bases, -1.7 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.
