Jon Singleton is a designated hitter for the Houston Astros. In 2025 he hit 0 home runs and knocked in 0 RBIs, notching 1 hit across 9 plate appearances in 3 games. His batting average was .111, 54.7% lower than the league average of .245. He reached base at a .111 clip and slugged .111, for an OPS of .222, 69.1% lower than the league mark of .719. He averaged 83.5 mph off the bat, hit 50.0% of balls in play at 95 mph or better and made contact on 84.6% of his swings. Adjusted for his ballpark and league, his -52 wRC+ puts his offence 152% below average. That comes to -0.2 dbWAR — -1.6 runs with the bat, -0.0 on the bases, -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.

Head to head
Put Jon Singleton beside up to three others.
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.
