Platoon splits
Platoon splits (EB/PA allowed)
He handles righty bats better than lefty bats, by 0.041 EB/PA allowed.
50% probable range: +0.034 to +0.050
vs LHB: shrunk estimate 0.470 EB/PA, 50% probable range 0.451 to 0.490, based on 119 plate appearances. Raw (unshrunk) rate: 0.440 EB/PA. League median vs LHB: 0.451 EB/PA.
vs RHB: shrunk estimate 0.429 EB/PA, 50% probable range 0.410 to 0.449, based on 115 plate appearances. Raw (unshrunk) rate: 0.433 EB/PA. League median vs RHB: 0.435 EB/PA.
His split is about typical for a righty arm (median 0.042). Against lefty bats he allows more than the league median, which is a real platoon weakness.
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

Pull side and opposite field depend on which side each batter hits from, so this pools every hitter he faced.
Batted balls allowed
Luck check
3 outs behind him came on balls the simulator values at 1.5 bases or more.
