In 1987, I went to the game hoping to get a Roger Clemens autograph. Unfortunately so did everyone else and I missed getting it direct from him.
So I'm getting others autographs and I hear one of them say, "I forgot my cup. I'm not going to face those aluminum bats without it." Me being the industrious teenager I was offered to get his cup from his car in the parking lot. He actually gave me his car keys and I went to the parking lot, retrieved his cup, put it in my back pocket, and returned inside the stadium. I gave him his keys and his cup back in exchange for The Rocket's autograph.
That player's name was Mike Konderla. Never forgot him or the story. Best autograph I ever got.
