How to read this chart
Each spoke is a skill estimate adjusted for sample size (not raw season stats), so farther out = better. Spokes are the metric itself; ↓ marks a rate where a LOWER number is better. The middle ring marks the league median and the outer ring the league best. Percentiles vs. 494 qualified pitchers — 100+ batters faced, starters and relievers pooled. He hasn't reached that bar himself, so he is measured against them rather than counted among them.

What he throws, and what it does

Kolby Allard mixes his four-seam fastball (34%) and cutter (23%). No pitch has beaten league-average results yet — the four-seam fastball has come closest.

Replacement level is per-batter and can't be split by pitch type, so the bars below use league average.

What they throw, how hard, and what misses bats — from pitch tracking, regular season only.

By appearance

How the stuff has held up outing to outing

One point per outing — how his velocity, movement, and pitch mix have moved across the season, with league context for scale. Each pitch keeps the same color in every chart. Only his four-seam fastball is in these charts — the rest were tracked too rarely to plot.

Platoon splits

How he fares against lefties and righties

Platoon splits (EB/PA allowed)

Better vs LHB than vs RHB by 0.038 EB/PA allowed (modeled).

50% probable range: +0.028 to +0.047

vs LHB20 PA0.450

vs LHB: shrunk estimate 0.450 EB/PA, 50% probable range 0.427 to 0.473, based on 20 plate appearances. Raw (unshrunk) rate: 0.595 EB/PA. League median vs LHB: 0.455 EB/PA.

Raw vs LHB rate (0.595) 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 lefty arm (median 0.038). Against righty bats he allows more than the league median — a genuine platoon vulnerability.

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

What hitters do when they connect

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.

How to read this chart
Dot color is estimated bases (EB) — what the contact was worth, regardless of what the defense did with it. 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.
