Allard 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 weakest skill is limiting home runs (8th percentile).

His grade rests on 45 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.

Pitch mix & swing-and-miss

−4 bases worse than a replacement arm this season

He allowed about 30 estimated bases, against a replacement arm's 26 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 0.6 bases against league average across 60 pitches, or 1.0 per 100 pitches.

Only his four-seam fastball is in the charts below, because the rest were tracked too rarely to plot.

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.

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. Only his four-seam fastball is in these charts, because the rest were tracked too rarely to plot.

Platoon splits

This section splits his results against lefties and righties.

Platoon splits (EB/PA allowed)

He handles lefty bats better than righty bats, by 0.038 EB/PA allowed.

50% probable range: +0.030 to +0.047

vs LHB20 PA0.449

vs LHB: shrunk estimate 0.449 EB/PA, 50% probable range 0.426 to 0.472, based on 20 plate appearances. Raw (unshrunk) rate: 0.595 EB/PA. League median vs LHB: 0.451 EB/PA.

His raw rate vs LHB (0.595) 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 0.487 EB/PA, 50% probable range 0.465 to 0.511, based on 25 plate appearances. Raw (unshrunk) rate: 0.744 EB/PA. League median vs RHB: 0.435 EB/PA.

His raw rate vs RHB (0.744) 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). Against righty 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

These cards show what hitters do when they make contact.

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.

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.
