With one out and a runner on third base, the batter hits a fly ball to right center field. The ball goes off the centerfielder's glove back into the air and the right fielder makes the catch. After the ball went off the centerfielder's glove, the runner from third took off for home, before the right fielder made the catch. The team in the field appeals the runner at third saying he left before the ball was caught. Is the runner out?
No, the runner is allowed to leave base as soon as the ball is touched, regardless of whether an out is recorded or not.
