Heuer allows more bases than most pitchers

The simulator expects him to allow 0.476 bases per batter faced, better than 18% of qualified pitchers. His best skill is limiting home runs (92nd percentile). His weakest skill is limiting hard contact (16th percentile). Short relief outings push strikeout rates up a little, so read his K% spoke with that in mind.

His grade rests on 46 batters faced, with data through 2026-09-27.

How to read this chart
Each spoke is a skill estimate adjusted for sample size, not a raw season stat, and farther out is better. A ↓ marks a stat where a lower number is better, and its spoke is flipped so farther out still means better. The middle ring marks the league median and the outer ring the league best. Percentiles compare him with 517 qualified pitchers, those with 100+ batters faced, starters and relievers together. He has not reached that bar himself, so he is measured against them rather than counted among them.

Pitcher type

This map shows what kind of pitcher he is, next to the league.

Arsenal

These cards show what he throws and what each pitch does.

Pitch mix & swing-and-miss

+3 bases better than a replacement arm this season

He allowed about 21 estimated bases, against a replacement arm's 24 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.

All pitches

He cost 1.5 bases against league average across 142 pitches, or 1.1 per 100 pitches.

His changeup isn't in the charts below, because only 46 of them were tracked with velocity and movement data this season.

He rarely throws his sinker (1% of his pitches).

How to read this chart
Each row is a pitch he throws at least 3% of the time, from pitch tracking in the regular season. The bar is how often he throws it, then its average velocity and its whiff rate, the share of swings that miss. Beside the velocity and the whiff rate is the median for that pitch, among pitchers of his hand for velocity and across the league for whiffs. More whiffs are better for a pitcher, while usage and velocity describe how he pitches. The Bases vs average bars score each pitch against a league-average pitch in the same count, and a bar to the left (saved) is better.

Mix by batter side

Compared with the league, his four-seam fastball tilts 16 points more toward righties.

48% vs RHH · RHP median 33%
Slider
25% vs LHH · RHP median 20%
42% vs RHH · RHP median 30%
How to read this chart
Each row shows how often he throws a pitch to left-handed hitters (LHH) and right-handed hitters (RHH), next to the median for pitchers of his hand (RHP median). Medians come from right-handed pitchers who throw that pitch at least 3% of the time. Between 217 and 384 of them qualify, depending on the pitch. A mix is a plan, so a higher or lower share is neither better nor worse. Overall results by batter side are under Platoon splits.

How to read this chart
Each dot is a pitch's current break in inches, averaged over his latest outings. Higher is more rise and further right is more arm-side break, and neither is better or worse. The faint trail runs from his early-season outings to the dot, and the soft halo shows how far normal noise can move it. League median is the small hollow ring, and a pitch marked * has none because too few pitchers throw it. The by-appearance chart below has the exact dates. More on the About page

By appearance

These charts follow his velocity, movement and mix from outing to outing.

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 changeup isn't in these charts, because only 46 of them were tracked with velocity and movement data this season.

Platoon splits

This section splits his results against lefties and righties.

Platoon splits (EB/PA allowed)

He handles righty bats better than lefty bats, by 0.041 EB/PA allowed.

50% probable range: +0.033 to +0.050

vs LHB26 PA0.508

vs LHB: shrunk estimate 0.508 EB/PA, 50% probable range 0.486 to 0.531, based on 26 plate appearances. Raw (unshrunk) rate: 0.370 EB/PA. League median vs LHB: 0.451 EB/PA.

His raw rate vs LHB (0.370) 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). 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

These cards show what hitters do when they make contact.

Batters go to the pull side off him most often, but they do the most damage up the middle.

Pull side and opposite field depend on which side each batter hits from, so this pools every hitter he faced.

How to read this chart
Dot color is estimated bases (EB), what the contact was worth no matter what the defense did with it. Darker means more bases, so a dark hollow ring in the outfield is a crushed ball his defense ran down. Tap or hover a dot or a row to link the two, and use the ▶ links to watch a play on Baseball Savant.
