Alan Trejo is a shortstop for the Colorado Rockies. In 2025 he hit 0 home runs and knocked in 1 RBI, notching 7 hits across 43 plate appearances in 13 games. His batting average was .175, 28.6% lower than the league average of .245. He reached base at a .190 clip and slugged .225, for an OPS of .415, 42.2% lower than the league mark of .719. He averaged 86.3 mph off the bat, hit 28.6% of balls in play at 95 mph or better, barrelled 5.7% of them and made contact on 77.9% of his swings. Adjusted for his ballpark and league, his 6 wRC+ puts his offence 94% below average. That comes to -0.3 dbWAR — -4.7 runs with the bat, -0.0 on the bases, +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.

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.
