Tommy La Stella was a designated hitter for the Seattle Mariners. In 2023 he hit 0 home runs and knocked in 2 RBIs, notching 4 hits across 24 plate appearances in 12 games. His batting average was .190, 23.3% lower than the league average of .248. He reached base at a .292 clip and slugged .238, for an OPS of .530, 27.9% lower than the league mark of .734. He averaged 86.6 mph off the bat, hit 12.5% of balls in play at 95 mph or better and made contact on 75.0% of his swings. Adjusted for his ballpark and league, his 54 wRC+ puts his offence 46% below average. That comes to -0.1 dbWAR — -1.4 runs with the bat, +0.0 for the ballpark, -0.0 on the bases, +0.5 on double plays, -0.5 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, 2023.

What he throws, how hard, how often it misses, and what hitters do with it.


Four-Seam Fastball	87.5%	21	75.8	1,781	38.1%	8.3%	6	—	—

Tommy La Stella's arsenal by usage. Velocity is average release speed in mph, spin in rpm, and whiff rate is misses per swing — the cleanest single measure of whether a pitch beats hitters. BAA and OPS are what hitters did against each pitch, credited to the one that ended the plate appearance, and are left blank under 15 at-bats.

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.
