Michael Stefanic is a second baseman for the Athletics. So far in 2026 he has hit 0 home runs and knocked in 4 RBIs, notching 9 hits across 28 plate appearances in 14 games. His batting average is .346, 41.9% higher than the league average of .244. He reached base at a .393 clip and slugged .385, for an OPS of .777, 8.2% higher than the league mark of .719. He averaged 90.1 mph off the bat, hit 30.0% of balls in play at 95 mph or better and made contact on 88.9% of his swings. Adjusted for his ballpark and league, his 110 wRC+ puts his offence 10% above average. That comes to 0.2 dbWAR — +0.8 runs with the bat, -0.2 for the ballpark, -0.1 on the bases, +0.2 on double plays, +0.2 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.

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.
