The infield fly rule in fastpitch softball protects runners and maintains fair play by preventing easy double plays on routine pop-ups. This call applies when an eligible infielder can catch a fly ball with ordinary effort, even if the defense mishandles the catch.
Understanding this rule helps players, coaches, and fans anticipate outcomes during close plays at first base. The following sections break down the rule mechanics, common scenarios, and strategic impact in a clear, actionable format.
| Rule Component | Definition | When It Applies | Immediate Effect |
|---|---|---|---|
| Infielder Coverage | First baseman, pitcher, catcher, or shortstop | Bases occupied, fewer than two outs | Batter ruled out regardless of catch |
| Ordinary Effort | Standard movement, no diving or extended reach | Umpire judgment on fly ball height and location | Call made immediately, live ball |
| Declared Infield Fly | Umpire shouts “Infield Fly, Batter is Out” | Before the ball is touched if defensible | Runners may advance at their own risk |
| Dropped Ball | Ball touches ground untouched by defender | Still treated as an out if rule properly called | Runners must tag up to advance safely |
Defining the Infield Fly Rule
How the Rule Protects Runners
The infield fly rule prevents a legal double play on a pop-up that an infielder can catch with routine effort. When the bases are loaded or there is a runner on first and second with fewer than two outs, the umpire declares an infield fly to stop the defense from intentionally dropping the ball for a strategic double play. Runners are not forced to advance, but they may attempt to do so at their own risk once the ball is in play.
Umpire Signals and Timing
Good officiating is essential for this rule because the call must happen early. The umpire raises one hand palm up, declares “Infield Fly” if the conditions are met, and signals that the batter is out. If the ball is caught, it is a live ball and runners can advance after tagging up. If the ball drops untouched in foul territory and settles, it is treated as a foul ball with no automatic out unless caught.
Game Situations That Trigger the Rule
Bases Loaded with Less Than Two Outs
This is the most common scenario where the infield fly rule is invoked. With a runner on every base, a routine pop-up in the infield would normally allow the defense to turn a quick 6-4-3 or 5-4-3 double play. The rule removes this automatic advantage and keeps the offensive pressure on the defense.
Runner on First and Second, Fewer Than Two Outs
When there is a runner on first and second and fewer than two outs, an infield fly call can protect the trailing runner from being forced out at third. The rule applies as long as the pop-up remains in fair territory and an infielder, with ordinary effort, has a legitimate chance to make the catch.
Strategic Impact on Offense and Defense
Offensive Awareness and Positioning
Offensive teams use the infield fly rule to their advantage by hitting high, softly hit balls into gaps where infielders might struggle to make an easy catch. Coaches often instruct hitters to aim for these shots when there are multiple runners, forcing the defense to either catch the ball cleanly or risk allowing runners to advance multiple bases on a drop.
Defensive Communication and Execution
On defense, early communication is critical to avoid collisions and misratching plays. Outfielders should back up the infield when an infield fly is declared, and infielders must be ready to secure the catch or let the ball drop intentionally without creating a force at another base. Clear signals and disciplined positioning reduce errors and keep game flow predictable.
Key Takeaways for Players and Fans
- The infield fly rule protects runners by preventing manipulative double plays on routine pop-ups.
- It applies when there are fewer than two outs and runners on base that create a force situation.
- Umpires declare the rule based on whether an infielder can make the catch with ordinary effort.
- Once declared, the batter is out even if the ball is dropped, provided it remains in fair territory.
- Runners must tag up after the ball is caught to advance legally and avoid being doubled off.
FAQ
Reader questions
Does the infield fly rule apply if the ball is bunted softly into fair territory?
No, the infield fly rule applies only to fly balls that can be caught with ordinary effort. A bunted ball that stays low and is not a fly ball is ruled a fair or foul ball based on where it settles and whether it rolls foul before reaching first or third base.
What happens if an infielder intentionally drops a ball after an infield fly is called?
The batter is still out as ruled, and runners must tag up to advance. If the defense intentionally drops the ball and it remains in fair territory, runners risk being doubled off if they do not quickly secure their base or advance safely. Umpires watch for attempts to manipulate the play after the infield fly declaration.
Can the infield fly rule be overturned on appeal?
Yes, if the umpire makes an initial call that is questioned, managers can request an appeal. The appeal must be made before the next pitch or play ends, and the ruling can be confirmed or changed based on video review or clear evidence of missed criteria such as fewer than two outs or an ineligible infielder attempting the catch.
Is the infield fly rule used in all fastpitch softball leagues?
Most competitive fastpitch softball leagues, including slow-pitch and modified-pitch formats, adopt the infield fly rule under standard international or national governing guidelines. Local youth, recreational, and travel organizations should verify their specific rulebook edition to confirm exact conditions and any league-specific variations.
