Jonatan Clase is a left fielder for the Toronto Blue Jays. In 2026 he hit 2 home runs and knocked in 6 RBIs, notching 6 hits across 25 plate appearances in 9 games. His batting average was .273, 11.9% higher than the league average of .244. He reached base at a .360 clip and slugged .545, for an OPS of .905, 25.9% higher than the league mark of .719. He averaged 86.8 mph off the bat, hit 35.7% of balls in play at 95 mph or better and made contact on 69.4% of his swings. Adjusted for his ballpark and league, his 150 wRC+ puts his offence 50% above average. That comes to 0.2 dbWAR — +1.5 runs with the bat, -0.0 on the bases, -0.3 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.

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.
