Inside the rec-league at-bat.
Most of what we know about hitting comes from professional baseball — from leagues with curveballs, scouting reports, and 95-mph fastballs. Rec-league softball plays by different rules. Here’s what the ball actually does when the rest of us swing.
44,078
— rec-league swings logged on Slug Stats between May 2017 and August 2026.
Small for a stats piece. Large enough to see what the ball actually does.
§1 The shape of an at-bat
Singles are the most common outcome of any plate appearance — 34% of swings turn into one.
Take 100 plate appearances and lay them out side by side. Some end in a hit. Most don’t. But the mix below is slowpitch’s own — a contact-first sport with an arcing pitch, no scouting reports, no pitch sequencing, and home runs as the headline stat. The shape that emerges doesn’t look like the major-league one.

The slowpitch signature
A rec-league hitter clears the fence roughly once every 23.2 at-bats. Comparable to MLB's home-run rate.
Walks beat strikeouts 1.3-to-1. MLB hitters strike out 2.4 times for every walk they draw; slowpitch flips that completely. Arcing pitches, generous zones, and hitters who came to swing — the ball stays in play almost every plate appearance.
§2 The typical batting line
On the whole, Slug Stats hitters slash .547 / .578 / .836.
Average, on-base, slugging — the three numbers every baseball card lives and dies by. Setting the slowpitch line against MLB’s 2024 baseline isn’t really a fair fight: the ball is in play almost every plate appearance, the pitch is an arc, and singles come cheap. The result is numbers a major-league hitter would spend a career chasing.

§3 Where the ball goes
Hitters pull the ball 43% of the time. Opposite-field contact is about half as common.
Plot every recorded ball in play and a shape emerges. The chart below is the same data, six times — scroll to walk through it.
Stage 1 of 6 — Every ball in play
Every recorded ball in play, all at once.
A random sample of 4,000 swings across every Slug Stats user — each dot one ball with a recorded landing spot, hits and outs alike.
Stage 2 of 6 — Pull side dominates
Rec-league hitters pull. A lot.
Pull-side contact runs about 1.7× the opposite field — 43% pulled, 25% the other way.
Stage 3 of 6 — Trajectory matters
Line drives produce most of the hits.
A line drive turns into a hit 94% of the time. A pop-up: 42%.
Stage 4 of 6 — Singles
Singles cluster up the middle and over the infielders' heads.
The most common outcome at the plate — about 34% of every plate appearance becomes a single.
Stage 5 of 6 — Doubles and triples
Extra-base hits find the corners and the gaps.
Together about 12% of every plate appearance — and roughly 3.5 doubles for every triple.
Stage 6 of 6 — Home runs
Home runs clear the fence.
One every 23.2 at-bats. The slowpitch signature.

§4 The one number that surprised us
Line up the trajectories, and the gap is staggering.
Every coach tells you to hit line drives. The data backs them up. A grounder turns into a hit roughly as often as a coin lands on its edge. A line drive turns into one more often than not.
Line drives
.938
batting average across 7,281 at-bats
Pop-ups
.425
batting average across 984 at-bats
A rec-league hitter who turns half their grounders into line drives raises their average by 513 points. That’s the difference between batting .547 and .804.
