NCAA 2-78 Tag
SECTION 78. The action of a fielder in touching a base with any part of the body while holding the ball securely and firmly in the hand or glove or touching a runner with the ball or with the glove while holding the ball securely and firmly in that hand or glove. The fielder shall maintain or regain control of his body and if he drops the ball due to his lack of body control or control of the ball, it is not a tag. A voluntary and intentional release is substantive proof of complete control.
Note: A ball stuck in a fielder’s glove remains alive. If the fielder tosses the ball/glove combination to another fielder in time to complete a tag of a base or runner in advance of the base and the ball/glove combination is held securely, the runner or batter-runner is out.
