U have to wait until the ball is caught to "tag up".
That is incorrect. Runners trying to advance on a fly ball may "tag up" and advance when the fielder first touches the ball. If that were no so, fielders could intentionally juggle the ball and attempt to pick the runner off who ran too early.
He needs to catch it, and if he drops it the runner doesn't need to tag up.
If the pitcher is in contact with the runner, the runner is safe if the pitcher drops the ball. If the pitcher is in contact with the rubber, it is a balk if he drops the ball.
No. A runner is out anytime while running to a base if he makes contact with the ball or the glove that the ball is in. On a pop-fly, a player with the ball only needs to touch the base the runner left from if the runner did not tag-up to the bag after the ball was caught.
yes he is out yes he is out
if the fielder is a) in the baseline, and b) doesn't have the ball, then no. If the runner goes out of the baseline to strike the fielder, he is out for leaving the baseline. If the fielder has the ball, and as a result of the collision he tags the runner, then runner is out. If the fielder has the ball and is trying to tag the runner, but the collision knocks the ball loose, then the runner is out if the umpire felt the contact was intentional, but it is a loose/live ball if the contact was accidental or otherwise part of the game.
its a catch
No, once the fielder comes in contact with the batted ball a runner cannot be called for runner interference unless he intentionally goes out of his way (basepath) to make contact with the fielder
If it was a hit ball and the ball was stuck in the runners jersey then the runner is out assuming he had the first contact with the ball. If a fielder has the ball stuck in the jersey then the ball is dead and the hitter would be safe at first.
The runner is probably out for interference by running into a fielder, if not, he is out if the throw to first beat the runner and the first baseman, or whom ever is covering first, had his foot on the bag when he received the ball.
No, in that situation the person with the ball would have to tag the runner for the runner to be out.
you catch the ball and if the runner has passed a base throw it to the next one.
No, the ball is not dead and the batter may attempt to hit it.
