definition infield fly rule softball
INFIELD FLY: An infield fly is a fair ball (not including a line drive or an attempted bunt), which can be caught by an infielder with ordinary effort when 1st and 2nd or 1st, 2nd and 3rd bases are occupied before two are out. Any fielder can catch an infield fly. NOTE: All divisions play with an infield fly rule. *NOTE: When it seems apparent that a batted ball will be an infield fly, the umpire(s) shall immediately declare, infield fly, the batter is out to aid the runners.
