Bidois is getting hit harder than most pitchers

The simulator expects 0.549 bases allowed per batter faced against him — better than 4th percentile of qualified pitchers. The soft spot is HR Suppression (2nd percentile). Short relief stints inflate strikeout rates a touch, so read the Strikeouts spoke with that in mind.

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.

Pitcher type

Two skills separate pitching styles: finishing hitters without free passes (strikeout rate minus walk rate, right = better) and keeping the contact they do allow soft (hard-hit rate against, up = better).

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 LHB45 PA0.591

Raw vs LHB rate (0.784) is off this scale — small samples like this are exactly why the shrunk estimate (the dot) is the trustworthy number, not the raw one.

vs RHB35 PA0.548

Raw vs RHB rate (0.344) is off this scale — small samples like this are exactly why the shrunk estimate (the dot) is the trustworthy number, not the raw one.

50% probable range: +0.034 to +0.050

About the typical split for a righty arm (median 0.041). He allows more than the league median against both sides.

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 Brandan Bidois 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.
