The simulator expects 0.456 bases allowed per batter faced against him — better than 45th percentile of qualified pitchers. His standout tool is Strikeouts (70th percentile). The soft spot is Command (20th percentile).
Each spoke is a skill estimate adjusted for sample size (not raw season stats), so farther out = better.
Percentiles vs. 424 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.

Plays like…
Same archetype, nearest by rate — the pitchers whose profile looks most like this one.
Joe Boyle mixes his slider (34%) and four-seam fastball (21%). His best pitch has been the slider, saving 2.0 bases per 100 thrown vs average, and his slider runs 2.0 mph above the league norm.

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.
Platoon splits
How he fares against lefties and righties
Platoon splits (EB/PA allowed)
Dot = shrunk true-talent estimate; bar = 50% probable range. Tap or hover any mark for its number, or tab to a row for all of them.
Faint diamond = his raw, unshrunk rate against that side — small samples make it noisy, which is why the model pulls the dot toward a more trustworthy estimate.
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.
Gray tick (marked “lg”) = league median vs that side; the faint gray band behind it spans the middle half of the league (25th–75th percentile).
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.

vs LHB: shrunk estimate 0.449 EB/PA, 50% probable range 0.427 to 0.472, based on 36 plate appearances. Raw (unshrunk) rate: 0.452 EB/PA. League median vs LHB: 0.422 EB/PA.

50% probable range: +0.033 to +0.049
About the typical split for a righty arm (median 0.041). Against lefty bats he allows more than the league median — a genuine platoon vulnerability.
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.
Batted balls allowed
Where every ball hit off Joe Boyle landed this season.
Dots are colored by estimated bases (EB) — pale slate (easy out) to dark teal (home-run territory).
Filled dots are hits; hollow rings are outs — a dark ring in the outfield is a crushed ball his defense ran down.
