Force play or tag play?

Teach learners to read the runners before they judge the out. This complete lesson turns one of baseball’s most important ideas into a repeatable decision path, then tests it through eight original game situations.

Teacher guide

Learning objectives

By the end of the lesson, learners should be able to:

  • distinguish a force play from a tag play;
  • identify which runners are forced when the batter becomes a runner;
  • explain why retiring the batter-runner can remove another runner’s force;
  • recognise caught-fly retouching as an appeal situation, not an ordinary force; and
  • decide whether a run scores when a third out is a tag play.
Core concept

Start with the right to the base

A force does not mean “the runner is moving.” It means the runner has lost the right to remain on a base because the batter became a runner and needs first base.

Runner on first: the batter-runner needs first, so R1 loses the right to stay there and is forced toward second.

The four-question check

  1. 1
    Where did every runner start?

    Mark the occupied bases before the pitch.

  2. 2
    Did the batter become a runner?

    If not, no new force chain was created.

  3. 3
    Who lost the right to stay?

    Follow the occupied bases from first toward home.

  4. 4
    Was the force removed first?

    If the trailing runner is retired, a tag may now be required.

Language of the lesson

Six terms learners need

Batter-runner
The batter after becoming entitled or required to run to first.
Forced runner
A runner who loses the right to a base because the batter became a runner.
Force play
A play on a forced runner. The defence may tag the runner or the base they must reach.
Tag play
An out that requires the defence to touch an off-base runner with the securely held ball or the hand or glove holding it.
Retouch / tag up
Touching the original base after a caught fly before advancing. A runner may leave from the fielder’s first touch.
Appeal
A clear defensive request for an umpire to rule on a missed base or an early departure that is not called automatically.
35-minute lesson

Teaching sequence

  1. 0–5

    Activate

    Ask: “A fielder touches a base before the runner arrives. Is the runner always out?” Do not confirm the answer yet. Collect reasons.

  2. 5–12

    Model the force chain

    Use three learners or markers as first, second, and third. Add a batter-runner and show how occupied bases create a chain. Remove the batter-runner first and ask what changes.

  3. 12–18

    Teach the four-question check

    Work through the decision path above. Contrast “runner on first” with “runner on second only.” Emphasise that running toward a base does not itself create a force.

  4. 18–30

    Make the calls

    Learners complete the eight situations independently or in pairs. Require one ruling and one decisive fact for each.

  5. 30–35

    Debrief

    Check the key together. Finish by returning to the opening question and asking learners to improve their first answer.

Learner sheet: force, tag, or appeal?

For each play, write the ruling and identify the one fact that decides it. These situations use the 2026 MLB Official Baseball Rules.

Name
Date
Decision reminder
  1. Mark the occupied bases.
  2. Ask who had to advance because the batter became a runner.
  3. Check whether another out removed that force.
  4. Decide whether the defence needed the base, the runner, or an appeal.
  1. 1

    The straightforward force

    0 outR1——

    The batter hits a ground ball to shortstop. Holding the ball securely, the shortstop steps on second before R1 arrives but never touches R1.

    Is R1 out?

    RulingDecisive fact
  2. 2

    A base touch is not always enough

    0 out—R2—

    The batter grounds to shortstop. R2 runs toward third. The third baseman receives the throw and steps on third before R2 arrives but does not tag R2.

    Is R2 out?

    RulingDecisive fact
  3. 3

    The out at first changes the play

    1 outR1——

    The batter grounds directly to first. The first baseman steps on first, retiring the batter-runner, then throws to second. The shortstop touches second before R1 arrives but never tags R1.

    Did the defence complete a double play?

    RulingDecisive fact
  4. 4

    The force returns

    0 outR1——

    On a ground ball, R1 reaches and touches second while the batter-runner is still running safely toward first. R1 then mistakenly retreats toward first. A fielder holding the ball touches second before R1 can return.

    Can R1 be out without being tagged?

    RulingDecisive fact
  5. 5

    Does the run count?

    1 outR1—R3

    The batter grounds to first. The first baseman steps on first for the second out, removing R1’s force. R3 then touches home before the shortstop tags R1 for the third out.

    Does R3’s run count?

    RulingDecisive fact
  6. 6

    Leaving before the touch

    1 out——R3

    A fly ball is caught for the second out. R3 left third before any fielder touched the fly and crossed home. Before the next pitch, the defence returns the live ball to third and clearly appeals the early departure.

    What is the ruling, and does the run count?

    RulingDecisive fact
  7. 7

    First touch or final catch?

    <2 out——R3

    R3 stays on third until an outfielder first touches a fly ball. The ball is juggled twice before the catch is completed. R3 leaves immediately after the first touch and reaches home.

    Was R3 allowed to leave when they did?

    RulingDecisive fact
  8. 8

    Extension: the grass is not the boundary

    1 outR1R2—

    A high fair pop descends on shallow outfield grass. The shortstop could catch it with ordinary effort, but an outfielder calls for it and the ball falls untouched. The umpire had declared “Infield fly.”

    Can that call be valid, and are R1 and R2 forced to advance?

    RulingDecisive fact

Answer key and reasoning

Credit an answer only when the learner identifies both the ruling and the fact that changes it.

  1. R1 is out.

    The batter becoming a runner forced R1 to leave first. Secure possession plus touching second before R1 arrives completes the force out; no tag is needed. Rule: 5.09(b)(6).

  2. R2 is not out.

    With second occupied but first empty, the batter-runner does not take away R2’s right to second. R2 chose to run and must be tagged while off a base. Touching third alone does nothing. Rule: 5.09(b)(4) and the Force Play definition.

  3. No double play.

    Retiring the batter-runner at first removed the reason R1 had to advance. The play at second became a tag play, so touching second was no longer enough. Rule: 5.09(b)(6) and the Force Play definition comment.

  4. R1 is out at second.

    R1 removed the force by touching second, but reinstated it by retreating toward the previously occupied base while the batter-runner still had the right to first. The defence could again touch second for the out. Rule: 5.09(b)(6).

  5. The run counts.

    The out at first removed R1’s force. The third out was therefore a tag play, and R3 touched home before that tag. Reverse the order and the run would not count. Rules: 5.08(a) and 5.09(b)(6).

  6. R3 is out on appeal; the run does not count.

    R3 left before the first touch and failed to retouch third after the catch. The defence appealed clearly and before the next pitch. This is an appeal out, not an automatic umpire call. Rules: 5.09(b)(5), 5.09(c)(1), and the approved rulings under 5.08.

  7. The departure was legal.

    A runner may leave from the instant the first fielder touches the fly ball. R3 did not have to wait through the juggle until the catch was completed. Rules: Catch definition and 5.09(c)(1).

  8. The call can be valid; the runners are not forced.

    The outfield grass and the eventual fielder do not decide an infield fly. What matters is whether an infielder could catch the qualifying fair fly with ordinary effort. The batter is out, the ball stays live, and removing the batter-runner removes the force on R1 and R2. Rule: Infield Fly definition.
