Jonathan Diaz is a shortstop for the Toronto Blue Jays. In 2015 he hit 0 home runs and knocked in 2 RBIs, notching 2 hits across 16 plate appearances in 5 games. His batting average was .154, 39.5% lower than the league average of .254. He reached base at a .267 clip and slugged .154, for an OPS of .421, 41.7% lower than the league mark of .721. He averaged 89.5 mph off the bat, hit 11.1% of balls in play at 95 mph or better and made contact on 91.2% of his swings. Adjusted for his ballpark and league, his 28 wRC+ puts his offence 72% below average. That comes to -0.1 dbWAR — -1.3 runs with the bat, -0.0 on the bases, +0.1 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.

Runners on includes runners in scoring position, which is the convention every reference uses. Rows under 25 plate appearances are marked thin — at that size a rate moves several dozen points on one hit. Counted from play-by-play, 2015.
Head to head
Put Jonathan Diaz 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.
