Softball
Bat-and-ball team sport related to baseball — played with a larger ball, an underhand pitch and a smaller diamond over seven innings.
What is Softball?
Softball is a team sport derived from baseball, invented in Chicago in 1887 as an indoor version and now played worldwide outdoors. Two nine-player teams (ten in slowpitch) alternate offence and defence over seven innings on a smaller diamond, pitching a larger ball underhand. The two dominant codes are fastpitch — the discipline played at the Olympics, in college and internationally — and slowpitch, popular for recreational and adult league play. Rule differences from baseball include mandatory underhand pitching, a shorter pitching distance (43 ft in women's fastpitch), a larger ball (11-12 in circumference), seven-inning games, and pitchers whose motion drives their momentum toward the plate rather than off a raised mound.

How it works
Objective
Score more runs than the opposing team over seven innings by batting and rounding the bases before three outs per half-inning.
Match structure
The visitors bat in the top of each inning, the home team in the bottom. Three outs end the half-inning; teams switch. Runs are scored the same way as baseball — round all four bases before three outs. After seven innings, the team with more runs wins. Extra innings use the tiebreaker in most codes.
Rules
Basic rules
Underhand pitch
Pitcher must deliver the ball underhand with a straight, whip-like motion — no overhead throwing.
Windmill motion
Modern fastpitch pitchers rotate the arm in a full circle at the hip, releasing near the front foot at high velocity (70+ mph elite women).
No leadoff (fastpitch)
Runners may not leave the base until the pitcher releases the ball; leaving early is an out.
Slowpitch arc
In slowpitch, the pitch must travel with a legal arc (6-12 ft above the ground); flat pitches are called illegal.
Seven innings
A regulation game is 7 innings, not 9.
Bunts
Allowed in fastpitch; illegal in most slowpitch codes.
Foul balls
Same as baseball — strike unless already at strike 2, when it stays a ball unless caught for an out.
Advanced rules
DP/FLEX rule (fastpitch)
Designated player bats for a defensive-only 'flex' player; allows a strong hitter and a strong defender to share one lineup slot.
Re-entry
Starting players who are substituted out may re-enter once, in their original spot.
Intentional walk
Coach may signal an intentional walk without pitching (like modern MLB).
Look-back rule (fastpitch)
Once the pitcher has the ball in the pitching circle, runners not committed to a base must stop and either return or advance immediately — no bouncing off.
Scoring
Runs are the only scoring unit — same as baseball.
| Action | Points |
|---|---|
| Single / double / triple / home run | 1 base / 2 bases / 3 bases / all four |
| Walk / HBP | batter to 1B |
| Sacrifice fly | runner scores from 3B |
Win condition · Higher score after 7 innings; extra innings with tiebreaker if tied.
Playing area
Called
diamond
Dimensions
60 ft baselines (18.3 m); pitching distance 43 ft (13.1 m) women's fastpitch, 46 ft (14.0 m) men's; outfield fence 200-250 ft (61-76 m).
Smaller diamond than baseball with a flat pitching circle (no raised mound). Fair territory extends between the two foul lines from home plate.
Equipment
Softball
11-12 inch circumference (larger than baseball); typically bright yellow with red stitching for visibility.
Bat
Aluminium or composite in most codes (wood allowed); shorter and lighter than baseball bats.
Glove
Fielding glove larger than baseball's, sized for the bigger ball.
Batting helmet
Required in fastpitch; typically has a face mask/cage.
Catcher's gear
Mask with throat guard, chest protector, shin guards.
Cleats
Rubber or metal (metal cleats banned in some age groups).
Positions & roles
Pitcher (P)
×1Underhand pitcher; often the highest-impact player.
Catcher (C)
×1Behind home plate, receives pitches, blocks the plate.
First baseman (1B)
×1Fields at first, receives throws for outs.
Second baseman (2B)
×1Right of second base; short throws.
Third baseman (3B)
×1Reactive infielder against bunts and slaps.
Shortstop (SS)
×1Between 2B and 3B; often the best athletic infielder.
Outfielders (LF/CF/RF)
×3Cover the outfield; slowpitch adds a fourth 'rover' outfielder.
Officiating
Home-plate umpire calls balls, strikes, and plate plays. Base umpires cover safe/out on force and tag plays.
- Home-plate umpire
- 1-2 base umpires
Strategies
Slap hitting
Left-handed hitters slap-hit while running toward first, using speed to beat throws.
Small ball
Bunts and steals matter more than in baseball because of shorter basepaths.
Rise-ball / drop-ball
Elite pitchers make the ball rise, drop, or curve within the strike zone.
Defensive shifts
Reading batter tendencies to position infielders and outfielders.

- Slap hit
- A left-handed swing while running toward first base to leg out infield hits.
- Drop ball

Frequently asked
Is softball the same as baseball?+
No — softball uses a larger ball, underhand pitching, a smaller field, 7 innings, and slightly different rules (no leadoffs in fastpitch, mercy rule, tie-breaker).
Why is the ball called 'soft'?+
Original 1887 balls were soft (a boxing glove tied with rope). Modern balls are firm — the name stuck from tradition.
What is the difference between fastpitch and slowpitch?+
Fastpitch has fast, flat pitches; slowpitch requires a legal arc, with 10 players per side and typically no bunts or stealing.
Do men play international softball?+
Yes — men's fastpitch has its own WBSC World Cup, but the Olympic version has been women-only since 1996.
Is softball at the Olympics?+
Women's fastpitch was an Olympic sport 1996-2008, returned for Tokyo 2020, and is back for Los Angeles 2028.
