"It’s sad, but there’s a myth in baseball that certain classes of players are more susceptible to fits of ‘dogging’ than others. This dread ballplayers’ palsy is widely believed to affect blacks more than whites, and Latins more than either. I have never seen anything to substantiate it, but the superstition is present in almost every locker room. For instance, Roberto Clemente did have a very capricious set of vertebral discs. He could play them for you like castanets – and would, on demand. But the grand old game was skeptical. “How can you bat .351 with a bad back?” the dugouts scoff. The point is Hemingway had to write best sellers standing up because of a bad back. John Kennedy had to run the country wearing a corset. But no one believed you could bat .351 with a bad back. Actually, Clemente himself fell into the trap one night when, speaking of Sandy Koufax’s reported sore arm, he asked a reporter irritably, “How can you strike out 15 batters a night with a sore arm?” Said the reporter gently, “Roberto, how can you bat .351 with a sore back?” Roberto got the point."
