Each spoke is a skill estimate adjusted for sample size — not raw season stats — so farther out = better. Spokes are the metric itself; ↓ marks a rate where a LOWER number is better. Percentiles vs. 499 qualified hitters — 50+ plate appearances. He hasn't reached that bar himself, so he is measured against them rather than counted among them.

Two skills separate hitting styles: not giving away at-bats (walk rate minus strikeout rate) and squaring the ball up when he does put it in play (hard-hit rate). Every dot is a qualified hitter this season; dot size tracks plate appearances. Click any dot to open that hitter's page.

Dot color is estimated bases (EB) — what the contact was worth, regardless of what the defense did with it. So a dark hollow ring in the outfield is a crushed ball that got caught. Tap or hover a dot or a row to link the two, and use the ▶ links to watch a play on Baseball Savant.

Bases added per 100 pitches of each type — the same scale as the pitcher pages’ “saved/cost per 100”, from the hitter’s side. Every pitch counts: taking a ball adds value, whiffing loses it, and the pitch that ends the plate appearance scores its outcome against the count’s expectation. Values are bases vs the league count-average: +3.5 means his results against that pitch have been worth about 3.5 extra bases per 100 seen. Types with fewer than 50 pitches seen pool into “Other”.
