"Sparky Lyle's most famous prank, however, involved birthday cakes. Because Lyle didn't pitch until midway through games, he had time to sneak into the Yankees' locker room and sit naked on the birthday cakes prepared for his teammates.
When the birthday cake was unveiled after the game, Yankees players found an imprint of Lyle's posterior on the cake."
Lyle was a frequent prankster and this one had me laughing. He was a superb pitcher - I hated seeing him come in to pitch against my team.
