Slowpitch Softball Rules


The main softball rules are very simple and easy to understand. They are even easier to understand if you have any experience of baseball rules or rounders rules. Softball is a sport where you can happily play by just understanding the basic rules. The Lions (or Dave to be precise) have created this complete list!

Rules of Softball #1: The Basic Game

The game

Slowpitch Softball is played by two teams of ten players each.
The teams take it in turns to bat and field.
The batting team is called the OFFENSIVE team and the fielding team is called the DEFENSIVE team.

Most Slowpitch Softball is played by mixed teams, where men and women play together in a 5:5
ratio. Slowpitch is sometimes played by single-sex teams as well.

The basics of Softball are very simple. A PITCHER pitches the ball to a BATTER who hits it
and runs around as many bases as possible before the ball is retrieved and returned under
control by the defensive team.

The aim of the game is to score more RUNS than the opposition and a run is scored when a player
on the batting team advances around all three bases and back to the home base (called HOME PLATE)
from whence he started. Unless you hit the ball so far that you can run around all the bases before it’s returned (a HOME RUN),
you’ll probably have to stop at one or more bases on your way around and wait for the next batter to hit the ball so you can advance further.
Meanwhile, the defensive team is trying to get batters and base runners OUT. As soon as three
players on the offensive team have made outs, the two teams switch: The defensive team comes in
to bat and the batting team goes out to the field to defend.
An inning is completed when each team has batted, and a full game consists of seven innings.

Players bat in a prearranged order (in mixed games men and women bat alternately).
After the last batter in the order has hit, the first batter comes up again.
If the final out in an inning is made by, say, the fourth batter in the order, then the fifth
batter will be the first to hit when the team comes in to bat again. Batters keep their place
in the batting order even if they were out last time they batted.

Rules of Softball #2: The Playing Area

A Softball playing area is contained within a 90-degree angle, and is usually called a DIAMOND,
because the central part of the playing field – the INFIELD – is diamond-shaped.
The OUTFIELD extends outward from the infield to a boundary, either actual or notional.
From above, the playing area looks like the illustration.
A team in the field

The light green area is known as FAIR TERRITORY and is where most of the action takes place.
The dark green area is called FOUL TERRITORY, where some action can take place.
Everything beyond this is called DEAD BALL TERRITORY because if this ball goes into this area,
all action stops. As a basic rule, the batter must hit the ball into fair territory.

You will often hear people referring to LEFT FIELD, CENTRE FIELD and RIGHT FIELD.
These terms mean exactly what they say. Left field is that part of the outfield
which is to the left as you look at the field diagram; centre field is the outfield area
behind second base; and right field is the outfield area to the right on the diagram.

Play begins when the pitcher (1) standing on the PITCHER’S PLATE, tries to pitch the ball across HOME PLATE,
a five-sided piece of heavy rubber, guarded by the batter, 50 feet away.
Each BASE (First Base, Second Base and Third Base) is marked by a foam filled bag.
For safety reasons, FIRST BASE often consists of a double sized base.

Rules of Softball #3: The Defensive Team

The job of the defensive team, known as FIELDERS, is to catch or stop any balls hit, with the
aim of preventing offensive players from advancing around the bases and scoring runs.
Each fielder has specific duties and a specific number, used for score-keeping:



  • PITCHER (1): The pitcher pitches the ball to the batter from the pitcher’s plate.
  • CATCHER (2): The catcher kneels or squats behind home plate.
  • FIRST BASE (3): This is often a busy position, as many balls will be thrown to first base in
    an attempt to put batters out who are running from home to first.
  • SECOND BASE (4): The second base player will guard much of the right side of the infield.
  • THIRD BASE (5): The third base player guards the area near third base.
  • SHORT STOP (6): The short stop stands between second and third base and tries to stop or catch
    any ball hit towards left field.


Outfield positions are not quite so rigidly defined as infield positions.
In general, however, the LEFT FIELDER (7) will play in left field.
The LEFT CENTRE FIELDER (8) will play to the left of the centre field area.
The RIGHT CENTRE FIELDER (9) will play to the right of the centre field area.
The RIGHT FIELDER (10) will play in right field.
The outfielder’s job is to catch or stop balls hit in their direction and return them
quickly and accurately to the infield.


Softball Rule #4: Pitching

In Slowpitch Softball, the ball is lobbed underarm and must have an arc which reaches at
least six feet and no more than twelve feet from the ground.
For a moment, let’s ignore the main object of the game, which is for the batter to hit the ball.
Suppose he doesn’t? What happens then?

Strikes and Balls

Between 6 and 12 feet

A pitched ball will be described (by the umpire) as either a STRIKE or a BALL.
Basically, a strike is a good pitch and a ball is a bad one.


  • Must be pitched from the pitching plate.
  • Must have an arc of between 6 and 12 feet from the ground.
  • Must not, in the opinion of the umpire, be too fast.
  • Must pass between the height of the batter’s knees and back shoulder as he stands at home plate in a normal batting stance.
  • Must pass across some part of the Strike Zone.

Some definitions:

The strike zone

  • THE STRIKE ZONE is an imaginary three-dimensional column of space corresponding to the
    shape of home plate. A ball passing through ANY part of this zone is called a strike.

  • A STRIKE is a pitched ball which fulfils all of the above conditions.
    In all other cases, the pitch is a BALL, unless the batter swings at it.

  • A STRIKE OUT occurs if three strikes are called against the batter and the batter
    hasn’t managed to hit the ball into Fair Territory.

A STRIKE is called if:

  • a pitch is good and the batter fails to swing, or swings and misses, or swings and hits
    the ball into Foul Territory (without it being caught) or into Dead Ball Territory

  • a pitch is bad (would be deemed a BALL) but the batter swings and misses it

A WALK occurs if:

  • A pitcher pitches four BALLS – bad pitches which the batter makes no attempt to hit.
    In this case the batter will walk to first base.

Softball Rule #5: Batting

A right-handed batter will stand to the right side of home plate (from the pitcher’s point of
view) and a left-handed batter to the left of home plate. Once a batter hits the ball into fair territory,
he/she advances counter-clockwise around the bases.

If and when you hit the ball into Fair Territory, you must run. You have no choice.
You must drop the bat down and run as fast as possible to first base (and on to further bases
if you think you can make them safely).
Remember that you must touch every base with your foot as you run past it,
and when you decide to stop at a base (apart from first base and home plate),
you must stop on it, not run past it.


A ball is considered to be FAIR if:

  • it lands in the outfield (i.e. in Fair Territory), and then rolls foul.
  • it is hit into Foul Territory, but then rolls into Fair Territory before it passes first
    or third base.
  • it hits either first or third base, no matter where it goes afterwards!

A ball is considered to be FOUL if:

  • it is hit into the infield (i.e. in Fair Territory) but then rolls foul before it
    passes first or third base.
  • it is hit into Foul Territory outside the infield and then rolls into Fair Territory.

NOTE: A ball touched by a fielder standing in fair territory is FAIR, a ball touched by a
fielder in foul territory is FOUL.

Softball Rule #6: Running the Bases

Once you’ve hit the ball you’re forced to run. If you are forced to run to a base, if any
defensive player is holding the ball and touches
that base with any part of his body, or the ball itself, before you get there, you are OUT.
(we’ll explain when you’re forced to run and when you’re not in a moment).
As a base runner you are never safe until you are touching a base. If at any point you are
touched with the ball (whether in or out of the glove) by a fielder
and you are not safely in contact with a base, you are out. This is called a TAG.

Now we’ll look more closely at when base runners are forced to run and when they’re not, and
what fielders have to do in these situations to put runners out:

Force Outs

A batter who hit’s the ball into fair territory is forced to run to first.
Let’s suppose that you have made it to first base safely and now the next batter comes up to bat.
Remember that you can only advance to second base or beyond if the next batter hits the ball or
receives a walk.

However, if the next batter hits the ball into Fair Territory without it being caught in the air,
you are forced to run towards second base because the batter-runner is coming to occupy first
base and no more than one runner per base is allowed. In any situation where you as a base
runner are forced to advance, the defensive team can put you out simply by throwing the ball
to a player standing on the base to which you’re advancing. This is called a FORCE OUT
(or Force Play). No tag is necessary, although the fielder can choose to tag you while you’re
between bases if he wishes.

A force out on first

Let’s suppose that you’re a base runner on first and the next batter hits a ground ball to the
short stop. You are forced to run to second, the batter-runner is forced to run to first,
and the defensive team has a choice of two possible FORCE OUTS: you or the batter-runner.
If they’re feeling ambitious and there are less than two outs, they can go for both of you.
If they’re successful, this is called a DOUBLE PLAY. Typically, the short stop would throw
the ball to the second base-player standing on second (that puts you out) and the second
base-player would throw immediately on to first base. If the throw reaches the first
base-player before the batter-runner reaches the base, they too would be out!

Force plays can apply at any base. For example, if there are base runners on all three base’s
(this is called BASES LOADED), then all the runners are forced to run on the next hit that
isn’t caught in the air, and the fielders could get a FORCE OUT at any base -
including home plate.

Tag Outs

Major League Baseball Glove.

You have probably already grasped the point that fielders must TAG OUT runners who are not
forced to run; simply standing on the base with the ball won’t do.
Say you are the first batter in the inning and you hit a DOUBLE (a hit that allows you get to
second base).
When the next batter hits the ball and runs toward first, you don’t have to advance if you don’t want to,
because no one is coming to occupy your base. if you do choose to head for third,
you are UNFORCED and to put you out, a fielder must tag you with the ball in hand or glove
before you reach your target base. in fact, you can turn around and run back to the base you
came from if that seems a wiser choice; no one is coming to occupy that base and it’s still

Catch Outs (ball is caught in the air)

An outfield catch

Suppose you’re on first base with less than two out and the next batter hits the ball in the air
towards an outfielder (this is called a FLY BALL, or, if it’s hit on a low, hard trajectory,
a LINE DRIVE). Well, as soon as the outfielder catches the ball before it hits the ground
(and the laws of physics tell you this will happen within seconds), then the batter is out -
at which point you’re no longer forced to run to second, since there’s no batter-runner coming
to occupy first. The force is off.

Instead, you can choose whether to advance to second or not and so the defensive team can’t get
you out with a Force Play. They can only get you out by tagging you with the ball: a TAG OUT
or Tag Play. That’s why, if the ball is hit in the air towards a fielder when you’re a forced
runner, you shouldn’t automatically take off for the next base, because the catch might be made
and the force removed.

AND HERE’S THE KEY POINT: you cannot advance to the next base on a caught fly ball unless your
foot is in contact with the base you’re already occupying when the catch is made, or afterwards.
This is called TAGGING UP. You must tag up before you can advance after a caught fly ball.
Why? it’s a rule!


Remember that we said you can overrun first base (or home), but not second and third,
where you can be tagged out if you’re not in contact with the base.
But running hard and then stopping dead on a small base isn’t easy!
One way to do this is to slide the last few feet into the base along the ground,
so that you come to rest on or in contact with the base with minimal loss of momentum.
Another reason to slide is that you will present a smaller and more difficult target for the
defensive player who might be waiting to tag you.
