On May 14, 1939 -- Mother's Day, ironically -- "Rapid Robert" was pitching for his Indians against the White Sox, with his whole family making the trip to Chicago to see the game.
According to Lyons Press' new book, "The Baseball Hall of Shame: The Best of Blooperstown" by Bruce Nash and Allan Zullo, one of Feller's pitches was fouled off by Marv Owen -- into the seats and into the face of one Mrs. Feller.
The foul ball broke her glasses, gave her a pair of black eyes and sent her to the hospital.
Feller continued to pitch, and eventually won the game 9-4.
"It was a one-in-a-million shot," he called it.
