Inside the data · Updated

44,078 at-bats — what the average swing actually does.

Drawn from every at-bat logged on Slug Stats, a stat tracker for softball and baseball. 7,553 players, 44,078 swings so far.

Selection-bias caveat. These are people engaged enough to log every at-bat on a tracking app, so the sample skews toward more committed players — and toward the leagues and levels those players happen to play in. Treat the numbers as one slice of the game, not the whole sport.

The comparison is structural, not predictive. This data comes from a different game — arcing pitches, smaller fields, generous zones, and contact-heavy at-bats — and produces a slash line that doesn’t exist at the professional level. The 2025 row is included as a familiar reference, nothing more.

K rate 5.6%, BB rate 7.5%. Walks beat strikeouts 1.3-to-1. MLB runs roughly 2.4 strikeouts per walk; the arcing pitch flips that ratio.

Methodology

Sample. 44,078 swings (24,527 logged by 1,010 users for themselves, 19,551logged by scorekeepers on behalf of teammates who don’t use the app). Synthetic seed accounts excluded.

Aggregation. The slash line averages every PA equally, not every player equally — so an active hitter influences the line more than someone with a single logged game. The spray chart samples up to 4,000 randomly drawn balls in play.

Frozen at. August 1, 2026 — numbers stay locked until the next refresh, so a quoted figure here matches what readers see when they click through. At-bats logged on Slug Stats before the next snapshot will be reflected then.
