A genuinely productive bat
Fernando Tatis Jr. squares the ball up — harder contact than 98% of qualified hitters. No real holes either — the weakest mark (walk rate) sits right around the league average.
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 Fernando Tatis Jr. 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.
