How do you defend first and third in fastpitch softball?

Call the defense before the pitch. With fewer than two outs in a close game, the defense watches the runner on third to protect the run. Anyone who sees the break yells "Home!" With two outs, throw through to second, because a tag there before the run scores ends the inning.

Before every pitch with runners on first and third:

• The catcher knows the call: no throw, the pitcher cut, a throw through, a cut in front of second, a fake, or a called pick at third.
• The middle infielders know who takes the bag and who cuts.
• The third baseman stays on third, behind the runner.

The calls are team convention. The rulebook decides when runners may leave, when the look-back rule holds them, and what fielders and the batter may not do. Fastpitch has no lead, so the play starts on the release.

What the offense runs, and the call that answers it

Every offensive look starts on the release.

• Straight steal. The runner on first goes on the release. Judi Garman and Michelle Gromacki give that runner two jobs: reach second, or draw a throw that lets the runner on third score.
• Delayed steal. The runner on first takes a few steps on the release, then goes on the catcher's throw back to the pitcher. Ralph and Karen Weekly call this the more common delayed steal.
• Early break. Fastpitch has none before the pitch. The fastpitch version comes after the release: the runner on first stops short of second, or gets caught on purpose, to pull a throw or a rundown while the runner on third waits.
• The runner on third's read. A walking start on the release, then go when the throw is past the circle and headed for second. Hold on a throw to the pitcher, a fake or a cut. That read is Rundown's convention.

Call	Catcher	Middle infield	Pitcher	Use it when
No throw	Holds the ball, looks the runner on third back	The cover still breaks to the bag	Takes the ball back facing the runners	12U, a blocked pitch, or a throw that will not beat the runner to second
Pitcher cut	Firm throw, chest high, to the pitcher in the circle	The cover takes the bag	Throws home if the runner on third breaks. If that runner holds, keeps the ball unless second is still a play	12U default with fewer than two outs
Throw through	Looks at third, then throws to the bag	The cover takes the throw. The other middle infielder backs up behind the bag	Off the throwing line	Two outs, a run you can afford, or a slow runner on third and an arm that beats the runner to second
Cut in front of second	Throws at the cut's glove, on the line to the bag	The cover is on the bag. The other middle infielder sets up a few steps in front of it: cuts and throws home on "Home!", or lets it through	Off the throwing line	14U and up, fewer than two outs
Look-back to third	Looks at third first and throws to second if that runner is back	As called	Off the throwing line	Any throw to second. The catcher's look, not the look-back rule
Fake throw	Full-arm fake to second, then throws behind the runner on third or runs at that runner	Both sell the throw	Off the throwing line	A runner on third who goes on the arm swing. Called before the pitch, 14U and up
Throw back to third	Throws straight to third, behind the runner	The cover still takes second	Off the throwing line	A runner on third who drifts farther each pitch. Called before the pitch, 14U and up

Every row is team convention. On every call, the third baseman stays on third and the first baseman goes back to first for a possible rundown, as Garman and Gromacki teach. Center field backs up second, left field third, right field first.

What the rulebook decides

Rules here come from USA Softball, NCAA and WBSC, read in full, and from NFHS (high school) through USA Softball's 2026 rule differences chart. We could not read Softball Canada's 2026 playing rules, which are sold by subscription, or the full NFHS book. Softball Canada's rule book applies to Canadian Championship play, and leagues may adopt or change it, so check your code. No code tells you which call to make.

Runners leave on the release

Under USA Softball, a runner who leaves the base before the ball leaves the pitcher's hand is out, the ball is dead, and no pitch is declared (8-7-S). The chart lists NFHS as the same (8-7-18). NCAA makes it a delayed dead ball and lets the defense take the play or the out (12.15.2). WBSC sets the moment as the pitcher's stride foot touching the ground (5.10.3). With nobody off a base before the pitch, the defense's picks come from the catcher.

The look-back rule needs the ball in the circle

Under USA Softball, the rule is in effect when the ball is live, the batter-runner has reached first or been put out, and the pitcher holds the ball with both feet in the circle (8-7-T). A runner off base may stop once, then must return or advance at once. NCAA (12.17) and NFHS (8-8-1, per the chart) also tie the rule to the batter-runner and the circle. Any play releases every runner: USA Softball counts a fake throw or any pitcher act that makes a runner react (Rules Supplement 34), and NCAA counts raising the throwing arm or a step toward the runner.

After a walk or a batted ball, the rule is on once those conditions are met. After a steal with the batter still at bat, the USA Softball, NFHS and NCAA text names the batter-runner, and we found no official ruling on that case. WBSC's circle rule applies after any pitch (5.10.3). So do not build the pitcher cut on the rule: it works on the throw alone, with the ball in the middle of the diamond. When the rule is on, the pitcher holds the ball in the circle and stands still.

A fielder without the ball cannot block a base

In every code here, a fielder who does not have the ball and is not fielding a batted ball commits obstruction by impeding a runner. USA Softball's order is catch the ball, then block the base, then tag (Rules Supplement 36). That covers the third baseman taking a pick throw, the cover at second and the catcher waiting on the cut's throw. The umpire awards the base the runner would have reached (USA Softball 8-5-B; NFHS 8-5-2; WBSC 5.10.2). A fake tag that impedes the runner is obstruction too (USA Softball; NCAA 9.5.4.5; WBSC 5.1.17).

The batter may not hinder the catcher's throw

Under USA Softball, the batter is out for stepping out of the box to hinder the catcher, actively hindering the catcher from the box, intentionally interfering with a throw, or interfering with a play at home. The ball is dead and runners go back (7-6-R to U). Delaying a swing to block the throw on a steal is interference (Rules Supplement 36). The chart lists NFHS as the same (7-4-4).

NCAA lets the defense take the play or the out, and with fewer than two outs a runner coming home is out instead of the batter. Under NCAA, a throw to a base that hits a batter standing in the box stays live unless the batter intentionally initiates the contact (11.20.2, Note 2). WBSC also puts out the runner trying to score when the batter intentionally interferes at home (5.4.4).

With two outs, the tag at second can beat the run

A steal of second is a tag play, not a force. If the tag is the third out and comes before the runner on third touches home, the run does not count (USA Softball 5-5-B). That is why two outs changes the call.

A throw out of play costs two bases

USA Softball awards two bases from the last base each runner touched when the throw was released (Rules Supplement 38). A pick throw to third that goes out of play scores the runner on third.

What the coaching staff decides

Everything in this section is convention. Another sound system works if every player knows it before the pitch.

Call it before the pitch

Give the call with the pitch, from a short menu, so the catcher, both middle infielders, the pitcher and the third baseman all have it. Garman and Gromacki note that young players may not decide in time, so the coach can make the call.

Who covers second, who cuts, who backs up

Name the cover and the cut in the call. Rundown's convention keeps normal steal coverage: the second baseman takes the bag against a right-handed hitter, and the shortstop against a left-handed hitter swinging away. The other middle infielder is the cut, or backs up behind the bag on a throw through. Garman and Gromacki, and Yvette Girouard in The Softball Drill Book, put the shortstop on the bag and the second baseman at the cut. Either works if the team knows which one is on.

Girouard's cut sets up a few steps in front of second, glove on the throwing line and body just off it, so the cover still sees the ball. Unlike a relay on a batted ball, here the pitcher can be the cut. Otherwise the pitcher gets off the throwing line.

The catcher looks at third first

Garman and Gromacki have the catcher look to third before any throw. What the catcher sees decides it:

• The runner on third is back near the base: run the call.
• That runner drifts farther each pitch: call the pick at third for the next pitch.
• That runner went on the arm swing: pull the throw and run straight at the runner to force a choice. Girouard's marker is the coach's box: past it, throw to third; halfway home, run at the runner.

Hold the ball when the call is no throw, after a blocked pitch, or when the throw will not get the runner from first and the run matters.

Outs and score set the call

• Fewer than two outs, close game: the run outranks the out. Use the pitcher cut or no throw at 12U. From 14U, add the cut in front of second and the fake.
• Two outs: throw through. Garman and Gromacki also list two outs as a time to make no play, which fits a catcher who cannot reach second on target.
• A run you can afford: throw through. That means a margin one run cannot change, or an inning with a run cap where the next run ends the inning anyway.
• Runner from first caught in a rundown: run that runner back toward first and check third every step. With fewer than two outs, throw home the moment the runner on third breaks. With two outs, finish the tag if it beats that runner home; if not, throw home.

One word for the break

Pick one word for the runner on third breaking. The third baseman, the pitcher and the first baseman yell it. Garman and Gromacki use "Home," and their cut throws home on the call without looking. Skip numbers if your infield already calls "Four" and "Six."

Take away the delayed steal

The Weeklys' delayed steal needs a lazy return throw and a pitcher who looks away. The catcher checks both runners and returns the ball firmly, and the pitcher catches it facing them. If the runner on third breaks while the return throw is in the air, the pitcher catches it and throws home. Running at that runner is a play, and a play lets the runner go back.

Age the teaching

USA Softball's divisional focuses start first-and-third play at 14U: infield defense, cutoff positioning for pitchers and catchers, runners' plays, and catchers taking control of first-and-third plays and delayed steals. At 16U, base running gets more aggressive and catchers begin calling their own game. The ladder below is Rundown's coaching judgment:

• 12U: With fewer than two outs, two calls: no throw and the pitcher cut. With two outs, throw through if the catcher can reach second on target. The third baseman stays on the bag, and everyone yells the break word. Teach the release rule and the look-back rule.
• 14U: Add the cut in front of second, the catcher's look at third, the fake and the called pick at third, the firm return throw, and the rundown on a runner from first who stops to draw a play. Name the cover and the cut in every call.
• 16U and up: The catcher calls from the menu, with the coach's override, and reads the score. Change looks so the offense cannot sit on one call, as Garman and Gromacki advise.

A 10-minute first-and-third block

Use a full infield, a center fielder, a left fielder, and runners in helmets. A coach or pitcher throws from the circle, and a batter in a helmet stands in the box without swinging. Rotate runners every rep.

1. Minutes 0 to 2, calls and the word. No runners. The coach names each call, and the catcher runs it. Another coach yells "Home!" at random, and the cut throws home.
2. Minutes 2 to 5, live runners. The coach tells the runner on third privately whether to go. At 12U, run no throw and the pitcher cut; from 14U, add the cut in front of second.
3. Minutes 5 to 8, the catcher's read. The runner on third walks off, drifts or goes on the arm swing, and the catcher picks the play. Score 2 for an out with no run, 1 for no run, 0 when the run scores.
4. Minutes 8 to 10, outs and score. Before each rep, call "one out, tie game," "two outs" or "up by six." The catcher names the call out loud before the pitch.

Count runs allowed, not throws.

Quick answers

How do you defend first and third in softball?

Call it before the pitch. With fewer than two outs in a close game, protect the run: throw to the pitcher in the circle, cut the throw in front of second, or make no throw. With two outs, throw through to second. The third baseman stays on the bag, and anyone who sees the runner on third break yells "Home!"

Who covers second base on a first-and-third steal?

Whoever your call names. One sound default keeps normal steal coverage: the second baseman against a right-handed hitter, the shortstop against a left-handed hitter swinging away. The other middle infielder cuts or backs up. Garman and Gromacki have the shortstop cover and the second baseman cut.

Should the catcher throw to second with runners on first and third?

With two outs, yes, if the throw can get there on target: a tag before the run scores ends the inning. With fewer than two outs in a close game, throw through a cut or after looking the runner on third back. At 12U, the throw to the pitcher is the safer default.

When should the runner on third go on a first-and-third steal?

When the throw is past the circle and headed for second. A runner who goes on the catcher's arm swing can be caught by a fake, a throw to the pitcher or a cut.

Does the look-back rule apply on a first-and-third steal?

Under USA Softball, after a walk or a batted ball, the ball must be live, the batter-runner must have reached first or been put out, and the pitcher must hold the ball with both feet in the circle. After a steal with the batter still at bat, the USA Softball, NFHS and NCAA text names the batter-runner, and we found no official ruling. WBSC's circle rule applies after any pitch. The throw to the pitcher works without the rule.

Is it interference if the batter stands in the box during the catcher's throw?

Not for standing still. Under USA Softball, the batter is out for stepping out of the box to hinder the catcher, actively hindering the catcher from the box, or intentionally interfering with the throw. Under NCAA, a throw to a base that hits a batter standing in the box stays live unless the batter intentionally initiates the contact.
