"He was the only player I ever saw who would hit a single to left field and round the base so hard he would get halfway to second and have to hit the dirt and slide to stop himself, then pop up and get back to first base. If the left fielder bobbled the ball, he would be into second easily – but he always got back to first if he had to. He played that hard and intensely all the time."
