Jason Adam
2026Grade
Rarely walks anyone and lets the defense work.
Adam has been below average at limiting bases
The simulator expects him to allow 0.459 bases per batter faced, better than 40% of qualified pitchers. His weakest skill is limiting home runs (29th percentile). Short relief outings push strikeout rates up a little, so read his K% spoke with that in mind.
His grade rests on 142 batters faced, with data through 2026-09-27.

Arsenal
Jason Adam mixes his slider (38%) and changeup (33%). His best pitch has been the slider, saving 3.6 bases per 100 thrown against league average.
Pitch mix & swing-and-miss
He allowed about 59 estimated bases, against a replacement arm's 74 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 saved 4.3 bases against league average across 544 pitches, or 0.8 per 100 pitches.
His sweeper isn't in the charts below, because only 39 of them were tracked with velocity and movement data this season.

By appearance
These charts follow his velocity, movement and pitch mix one outing at a time, and each pitch keeps the same color in every chart. The velocity and movement charts also shade the middle of the league for scale. His sweeper isn't in these charts, because only 39 of them were tracked with velocity and movement data this season.
Platoon splits
Platoon splits (EB/PA allowed)
He handles righty bats better than lefty bats, by 0.040 EB/PA allowed.
50% probable range: +0.032 to +0.048
vs LHB: shrunk estimate 0.470 EB/PA, 50% probable range 0.448 to 0.490, based on 67 plate appearances. Raw (unshrunk) rate: 0.333 EB/PA. League median vs LHB: 0.451 EB/PA.
His raw rate vs LHB (0.333) 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.
vs RHB: shrunk estimate 0.429 EB/PA, 50% probable range 0.410 to 0.451, based on 75 plate appearances. Raw (unshrunk) rate: 0.505 EB/PA. League median vs RHB: 0.435 EB/PA.
His raw rate vs RHB (0.505) 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 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
Contact allowed
Batters go to the pull side off him most often, and that's also where they do the most damage.
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
One out behind him came on a ball the simulator values at 1.5 bases or more.
2 hits off him had less than a 20% chance of being hits.
