Buck Showalter tells the story of a game he managed in the minors where his team hit into a triple play without the defense touching the ball. How did it happen?
Runners were on 1st and 2nd, none out. On a 3-2 pitch, the runners go. The ball is popped up in the infield so the batter is out because of the infield fly rule. The runner on 2nd goes back toward 2nd base, but the runner on 1st does not and he passes the runner on 2nd, so the runner on 1st is out. The runner on 2nd is then hit in the head by the ball as it falls from the sky. He's out. 3 outs and not a single defender touched the ball.
Even funnier is Buck explaining how he had to make his nightly call to George Steinbrenner with his report on the game and explain that to Mr. Steinbrenner.
