Infield Fly Rule
A rule where the batter is automatically out on an easily catchable fly ball in the infield with runners on first and second (or bases loaded) with less than two outs.
Example Usage
“The umpire called 'infield fly' on the pop-up, so the batter was out even though the shortstop dropped it.”
Infield Fly Rule
The infield fly rule automatically declares the batter out when a fair fly ball can be caught by an infielder with ordinary effort, when there are runners on first and second (or bases loaded) with less than two outs.
Purpose of the Rule
The rule exists to prevent unfair double or triple plays. Without it:
- Infielder could intentionally drop the ball
- Runners, forced to stay near their bases, would be easy outs
- Defense could get 2-3 outs on a simple pop-up
When It Applies
The infield fly rule requires ALL of these:
- Runners on first AND second (or bases loaded)
- Less than two outs
- Fair fly ball (not a line drive or bunt)
- Ball can be caught with "ordinary effort" by an infielder
What Happens When Called
- Batter is OUT immediately (even if the ball is dropped)
- Runners can tag up and advance at their own risk
- The ball is LIVE
- If the ball is dropped, runners aren't forced
The Umpire's Call
The umpire must call "Infield fly, batter is out!" (or "Infield fly, if fair!") while the ball is in the air. The call must be made before the ball lands.
Famous Infield Fly Controversy
The 2012 NL Wild Card Game featured a controversial infield fly call when shortstop Andrelton Simmons caught (dropped?) a ball in shallow left field, sparking debate about what constitutes "ordinary effort."
