Edwin Díaz
2026Grade
Below league average across the board.
Díaz is getting hit harder than most pitchers
The simulator expects 0.485 bases allowed per batter faced against him — better than 10th percentile of qualified pitchers. His standout tool is Strikeouts (92nd percentile). The soft spot is Quiet Contact (16th percentile). Short relief stints inflate strikeout rates a touch, so read the Strikeouts spoke with that in mind.

Edwin Díaz leans on his four-seam fastball (57% of pitches). No pitch has beaten league-average results yet — the four-seam fastball has come closest.
Pitch mix & swing-and-miss
allowed 40 bases vs a replacement arm's 41 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.
8.2 bases cost vs league average, across 312 pitches — 2.6 per 100.

Edwin Díaz's pitch movement, 2026

Compared with his own earlier outings this season, not with other pitchers — and after taking out the drift every pitch in the league shows through midsummer.

Platoon splits
Platoon splits (EB/PA allowed)
Better vs RHB than vs LHB by 0.042 EB/PA allowed (modeled).
50% probable range: +0.034 to +0.051
vs LHB: shrunk estimate 0.507 EB/PA, 50% probable range 0.484 to 0.528, based on 50 plate appearances. Raw (unshrunk) rate: 0.536 EB/PA. League median vs LHB: 0.455 EB/PA.
vs RHB: shrunk estimate 0.465 EB/PA, 50% probable range 0.442 to 0.486, based on 29 plate appearances. Raw (unshrunk) rate: 0.576 EB/PA. League median vs RHB: 0.438 EB/PA.
Raw vs RHB rate (0.576) is off this scale — small samples like this are exactly why the shrunk estimate (the dot) is the trustworthy number, not the raw one.
About the typical split for a righty arm (median 0.043). He allows more than the league median against both sides.
How to read this chart
- Tap or hover any mark for its number, or tab to a row for all of them.
- His raw rate is the unshrunk number against that side — small samples make it noisy, which is why the simulator pulls his estimate toward a more trustworthy value.
- “Middle half of the league” is the 25th–75th percentile of all pitchers against that side.
- These are bases allowed, so lower is better. Weighted by how often he faces each side, the two splits average back to his modeled overall EB/PA allowed — not the xEB/PA headline at the top of the page, which folds in strikeouts and walks differently.
- Shrunk splits beat raw splits on held-out seasons, most decisively at low batters-faced counts (relievers especially), and converge with the raw numbers as exposure builds.
Contact allowed
Batters go to the pull side off him most often, and that's where the hardest contact comes from.
Pull and oppo are relative to each batter's stance, so this pools all the hitters he faced.
Batted balls allowed
Luck check
Burned 3 times — balls with a hit probability under 20% that found grass anyway.
