Wrigley Field's scoreboard is a giant board that has loomed over the bleachers since 1937. No batted baseball has ever struck it, the Cubs say, not even Roberto Clemente's legendary blast. A golf ball did. On April 17, 1951, Sam Snead hit two balls off the grass at home plate, no tee. His first shot struck the board. His second cleared it clean. Frankie Frisch just stared. "Look, he didn't even wiggle."
