Infield fly rule
The infield fly rule was a rule in the sport of baseball that was "invoked in instances where, with both first base and second base occupied, or with first, second and third base occupied... [..] And fewer than two out, the batter hits a high fly which in the judgment of the umpire can readily be caught by an infielder or the  or catcher inside fair ground. The batter is then called out regardless of whether the ball is subsequently caught or not. An attempt to bunt, however, under the conditions noted above, which results in a fair fly shall not be regarded an infield fly." ()
