[Jim Porter]

PLAY: The batter smacks the ball down into the soft dirt, and it dribbles slowly up the first baseline. The batter is off with contact, and the catcher is close on his heels. The BR avoids contact with the ball as he passes it, while F2 follows closely behind the BR. As F2 reaches down to glove the ball, the BR's heel hits F2's glove during the BR's back-stride, and the tripped BR falls flat on his face. F2 picks up the ball and tags the BR, who's still lying in a heap on the ground.
