If a fielder catches a fly ball and falls over the center field fence is it an out or a home run?
If the player holds on to the ball and it is determined that it did not touch the ground, it is an out. If the player drops the ball while falling over the fence, it is a home run.
To get more technical, I think as long as the fielder has his feet inside the area of the field of play, it would be an out. If the entire body (including feet) are over the fence when the catch is made, then it would be a home run.
The above answer is wrong.
If a fielder leaps and catches the ball before he touches dead ball territory the catch is good and the batter is out. It doesn't matter where he is in relation to the fence. He could be ten feet into dead ball territory and as long as he hasn't touched the ground, the catch is valid.
