Jose Canseco was a powerful slugger during his career (1986-2002, 462 home runs), but never a great outfielder. On May 26, 1993, a fly ball hit by the Indians' Carlos Martinez bounced off Canseco's head and into the stands for a home run.

This cap was worn by Canseco during the game. After the game, angry at himself for his embarrassing misplay, Canseco signed and wrote the date and city in which the strange event took place on the cap and, then, gave it away.
