If a fielder catches a ball and falls into the stands, it is a dead ball and all runners advance one base. Rule 704(c) The fielder made a legal catch. At that point the batter was out. The fielder then took the ball out of play. At that point the runners were allowed to advance one base.
If the fielder falls into the stands or the dugout after catching the foul, the ball is dead and runners are awarded base from the base they occupied at the time of the pitch.
Only when caught by a fielder, excluding softball.
Yes, for the fielder who catches it
If he catches the ball, the fielder's position doesn't matter.
No, if the fielder is out of the field of play (in the stands), then the batter is not out.
It is scored as a triple Really, no he caught the ball so obviously he got him out First answer is correct, batter is awarded three bases.
If it is caught by the player in the stands with no interference (such as a fan tipping the ball up), it is an out.
No. If the ball hits your glove or bat, then you're out. But other than that, you cannot be given out caught by fielder.
If the glove or mitt falls off in the process of catching the ball, it is not a legal catch. The fielder must have control of the ball in the glove and then remove it himself.
A "trap" happens when a fielder catches a line-drive or flyball on the first small bounce after hitting the ground. If the fielder caught the ball in the air, it would be an out. But because they caught it after the first hop, it is not an out. The term "trap" is used when the ball barely touches the ground, before the fielder grabs it.
