Decide before the pitch
Count the outs and locate each runner. Say where your first throw would go on a ground ball and who covers that base. On a bobble, look again: the available out may have changed.

Quiz Mode: try each answer before checking the explanation.
Coach View: use the answers and teaching notes to guide practice.
Secure and communicate
Move to the ball under control, field it before rushing a throw, and call for a fly ball early. A teammate should know whether to cover a base or back up a throw.
Force or tag?
A force exists because the batter becomes a runner and pushes another runner toward the next base. If an out removes that push, touching the next base alone may no longer retire the runner. In divisions with an infield-fly rule, the called batter is out; runners are no longer forced forward, the ball stays live, and an off-base runner may need a tag.
See example: Short feed and cover
Recognize an infield fly
With fewer than two outs and runners on first and second, or the bases loaded, a fair fly that an infielder can catch with ordinary effort may be an infield fly. A bunt or line drive is different. Keep playing because the ball stays live.
Make a backup plan
On a bunt, name the charging fielder, the base cover and the backup before the pitch. On any throw, move behind the likely target so a miss does not travel farther.
Practice it here
Point to the covered base before charging a short ball. Ask which Mustang lead choice the league uses before rehearsing a runner leaving a base.
Situation 01
Know your next play
Before each pitch, the shortstop checks the outs, runners and likely force play, then shares the coverage call with the second baseman.
- 1 Pitcher
- 2 Catcher
- 3 First base
- 4 Second base
- 5 Third base
- 6 Shortstop
- 7 Left field
- 8 Center field
- 9 Right field
Coach answer: Where you will play the ball and who covers the next base A fielder needs both a first play and the teammate covering the target. Otherwise a good throw can find an empty base.
Coaching Points
Ask two adjacent defenders to repeat the same coverage call.
Common Mistakes
Knowing your own job is not enough when the next base is uncovered.
Alternative Considerations
The coach may change alignment by hitter and score; communicate the change.
Coaching tip
Situation 02
Secure the routine out
A ground ball comes with no realistic play on the lead runner. Field under control and choose the available out instead of forcing a late throw.
Coach answer: Take the available out with a controlled throw Secure the ball and take the out that is still available. A late throw at a runner who is already safe adds risk.
Coaching Points
Rehearse the first choice and a fallback when the ball is bobbled.
Common Mistakes
A predetermined throw can survive in a player's mind after the play changes.
Alternative Considerations
Late-game score and outs may justify a different risk; name it before the pitch.
Coaching tip
Situation 03
Know when the force disappears
With runners on first and second and one out, the umpire declares an infield fly on a qualifying fair fly. It drops untouched in fair territory, so the batter is out and the ball remains live.
Coach answer: Tag the runner; the batter's out removed the original force After an infield-fly batter out, the original force disappears. On a dropped ball, tag an off-base runner instead of just touching the next base.
Coaching Points
Keep the ball live, identify the runner's actual obligation and use a tag when there is no force.
Common Mistakes
Do not confuse an out on the batter with a dead ball for everyone.
Alternative Considerations
If the fly is caught, runners still have retouch responsibilities. Walk the caught and dropped versions separately.
Related rule or safety source: Infield fly
Situation 04
Read a possible infield fly
First and second are occupied with one out. A fair fly, not a bunt or liner, can be caught by an infielder with ordinary effort.
Coach answer: Infield fly; remain aware that the ball is live The umpire can call an infield fly under the right outs and runner conditions. The ball stays live, so keep playing.
Coaching Points
The umpire judges ordinary effort; defenders should keep working through the play.
Common Mistakes
A fixed grass line does not decide ordinary effort.
Alternative Considerations
With two outs, or only first occupied, this particular infield-fly setup is absent.
Related rule or safety source: Infield fly
Situation 05
Assign bunt coverage
The coach calls a bunt defense. The charging fielder, base cover and backup player repeat their jobs before the next pitch.
Coach answer: One clear fielder, a covered target and a backup One fielder takes the short ball, another covers the target and a third backs up. Everyone charging leaves a base open.
Coaching Points
Walk through the rotation without a ball, then add a controlled bunt.
Common Mistakes
Two fielders charging can leave a base empty.
Alternative Considerations
Use different calls for runners on first and first-and-second; do not improvise a universal rotation.
Coaching tip
Situation 06
Defend a permitted lead
In this practice, the coach says runners may lead before the pitch. Other Mustang leagues may make runners wait; ask which rule your team uses.
Coach answer: Practice a legal throw and a controlled receiving tag under the stated lead rule Mustang lead timing depends on the adopted option. Rehearse a legal throw and controlled receiving tag under that option.
Coaching Points
Use a slow demonstration, clear receiver communication and safe tag spacing before adding speed.
Common Mistakes
A field dimension does not supply a rule, and a legal play is not a license for unsafe contact.
Alternative Considerations
For Mustang, repeat the exercise explanation whenever the adopted 9(O) option or occupied base changes.
