Ian Happ walks at an elite clip — better than 92% of qualified hitters. The strikeouts pile up, though — only 19% of qualified hitters whiff more often.
Each spoke is a skill estimate adjusted for sample size — not raw season stats — so farther out = better.

Plays like…
Same archetype, nearest by rate — the hitters whose profile looks most like this one.
Every plate appearance ends one of three ways: a strikeout (0 bases), a walk (1 base), or a ball in play worth its estimated bases.
The bar splits his value into those pieces, versus the league.
More bases is better. In the table, 100th percentile = best in MLB.

Platoon splits
Platoon splits (EB/PA)
Dot = shrunk true-talent estimate; bar = 89% credible interval.
Faint diamond = his raw, unshrunk rate against that hand — small samples make it noisy, which is why the model pulls the dot toward a more trustworthy estimate.
Shrunk splits beat raw splits decisively at low PA counts and converge with them as playing time builds — individual platoon gaps need roughly 1,000+ PA vs a hand before the raw number alone can be trusted.
Ian Happ switch-hits — he can choose the platoon-advantaged side almost every plate appearance, so a small gap here is expected. It is not missing data or a modeling error.
Headline EB/PA (0.496)
vs LHP115 PA0.480
vs LHP: shrunk estimate 0.480 EB/PA, 89% credible interval 0.426 to 0.531, based on 115 plate appearances. Raw (unshrunk) rate: 0.382 EB/PA.
Raw vs LHP rate (0.382) 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 RHP280 PA0.503
vs RHP: shrunk estimate 0.503 EB/PA, 89% credible interval 0.458 to 0.544, based on 280 plate appearances. Raw (unshrunk) rate: 0.538 EB/PA.

89% credible interval: -0.019 to +0.066
That interval crosses zero, so the model can’t confidently say which side he’s actually better against.

Best batted balls
Where every ball Ian Happ put in play 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 that got caught.
