In baseball, a fly ball is a batted ball that is hit high into the air, giving fielders time to move under it and make a catch. Fly balls are typically hit with a high degree of backspin, which causes the ball to stay in the air longer and travel a greater distance than line drives or ground balls.
When a batter hits a fly ball, the fielders on the defensive team will try to catch the ball before it hits the ground. If the ball is caught before it hits the ground, the batter is out and the play is considered a fly out.
If the fielder is unable to catch the ball, it is considered a fly ball hit and the batter becomes a baserunner, assuming they have hit the ball in fair territory. The baserunner may then attempt to advance to second or third base, or even score a run, depending on the position of the ball and the number of outs.
Fly balls can be hit to any part of the field, and fielders must be able to move quickly and position themselves properly to make a catch. Outfielders are typically responsible for catching fly balls hit to the outfield, while infielders will typically catch fly balls hit to the infield.
In conclusion, a fly ball is a batted ball that is hit high into the air, giving fielders time to move under it and make a catch. It is an important part of the game of baseball, as it allows batters to advance around the bases and score runs, while requiring fielders to be quick and nimble in their movements.
