Pitch mix & swing-and-miss
He allowed about 321 estimated bases, against a replacement arm's 383 over the same batters faced.
Replacement level is per-batter and can't be split by pitch type, so the bars below use league average.
He cost 39.2 bases against league average across 2,493 pitches, or 1.6 per 100 pitches.

Platoon splits
Platoon splits (EB/PA allowed)
He handles lefty bats better than righty bats, by 0.040 EB/PA allowed.
50% probable range: +0.031 to +0.048
vs LHB: shrunk estimate 0.460 EB/PA, 50% probable range 0.442 to 0.476, based on 196 plate appearances. Raw (unshrunk) rate: 0.437 EB/PA. League median vs LHB: 0.451 EB/PA.
vs RHB: shrunk estimate 0.499 EB/PA, 50% probable range 0.483 to 0.515, based on 460 plate appearances. Raw (unshrunk) rate: 0.542 EB/PA. League median vs RHB: 0.435 EB/PA.
His raw rate vs RHB (0.542) is off this scale. Small samples can push a raw rate this far, which is why the dot, the shrunk estimate, is the number to trust.
His split is about typical for a lefty arm (median 0.038). He allows more than the league median against both sides.
How to read this chart
- Each dot is his estimate against that side, with its 50% probable range as the bar. These are bases allowed, so lower is better.
- The diamond is his raw rate, which small samples make noisy, so the simulator pulls the dot toward a more trustworthy value.
- The dashed tick is the league median, and the shaded strip is the middle half of pitchers with 100 or more batters faced.
- The two splits average back to his modeled overall EB/PA allowed, not the xEB/PA headline.
- Tap or hover a mark for its number. LHB and RHB are left- and right-handed batters. More on the About page
Contact allowed
