Quick Summary

In baseball, a "fly ball" is a batted ball hit high into the air. This is one of the ways a batter can get on base if it's hit out of the reach of fielders. Other types of batted balls include ground balls and line drives, which are hit closer to the ground. A "big fly" is an informal term for a home run. An "infield fly" is a specific rule in baseball that applies to a fair fly ball hit within the infield when there are fewer than two outs and runners on first and second, or first, second, and third base. In this situation, the batter is automatically out.12345
