nothing if you leave early you better hope the pitcher pitches the ball and doesn't see you steal.
a steal or balk
No, a runner cannot steal on a foul tip during a baseball game.
No, the runner is not allowed to steal a base before the pitcher throws the ball.
No. The balk happens before the pitch, so the play is called dead and the runner is allowed to advance rather than attempt the steal. This happens some times, the pitcher will commit the balk because they see the runner make the break to steal, they don't get to make a throw to a base or to the plate because the umpires stop the play to call the balk.
If the player was stealing as the pitch was delivered, it is a steal. If, however, he leaves once the ball passes the catcher, it is not a steal. If a player is stealing, and there is a wild pitch allowwing the runner to reach third base, it would be a steal and a wild pitch.
NO
ed Parker isn't
No. You don't have to steal. But you do have to advance to the next base if a runner is about to occupy the base you just left from.
Just touch the runner on base.
steal of home
Either the second basemen or the short stop in responsible for covering second when a runner is trying to steal.
If the runner was not on the base at the time when the pitcher entered the pitching circle they can still steal a base. The runner has a certain amount of time to decide to either steal or return to their original base once the pitcher is in the circle. They cannot rock though, or pretend to go either way and then go the other. Once they commit to one direction they have to go that direction, unless the ball leaves the pitcher's circle again.
