Marcus Semien keeps the strikeouts in check — strikes out less often than 73% of qualified hitters. The contact is soft, though — only 26% of qualified hitters hit the ball with less authority.
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.

Best batted balls
Where every ball Marcus Semien 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.
