Runners on first and second (or bases loaded) with fewer than two outs.

Start playing free

  1. Any pop up with two outs
  2. Runners on first and second, fewer than two outs ✔
  3. Only with the bases empty

Why: The infield fly rule applies to a fair, easy pop up with runners on first and second, or the bases loaded, before two are out. It stops fielders from dropping the ball on purpose to get a double play.

Huh, didn't know that: Line drives and bunts can never be an infield fly.

The dad joke
Why was the pop up so smug? It knew the rules were on its side.
