 and other sports, neither secure possession for a time nor for a number of steps is enough to demonstrate that a catch has occurred. A fielder may, for example, appear to catch and hold a batted ball securely, take a few more steps, collide with a wall or another player, and drop the ball. This is not a catch.

The fielder must catch the ball with his hand or glove. If the fielder chooses to use his cap, protector, pocket or any other part of his uniform in getting possession, it is not a catch.

, and then is caught by another defensive player.

A catch is legal if the ball is finally held by any fielder before it touches the ground. Runners may leave their bases the instant the first fielder touches the ball. A fielder may reach over a fence, railing, rope or other line of demarcation to make a catch. He may jump on top of a railing, or canvas that may be in foul ground. No interference should be allowed when a fielder reaches over a fence, railing, rope or into a stand to catch a ball. He does so at his own risk.

If a fielder, attempting a catch at the edge of the dugout, is “held up” and kept from an apparent fall by a player or players of either team and the catch is made, it shall be allowed.

To avoid ambiguity with the common term catch meaning any action that gains possession of a ball, some may say that a fielder gloved a thrown ball or a batted, bouncing ball.
