On May 16, 1957 — The Yankees top Kansas City, 3 – 0, behind Bob Turley’s four-hit shutout. Mickey Mantle has a homer off Alex Kellner, the 11th time in his last 12 at-bats he’s reached base safely. That night a group of Yankees celebrate Billy Martin’s 29th birthday in raucous fashion. An ensuing fight at Manhattan’s Copacabana Club leads to $5,500 in fines and the eventual trade of Billy to Kansas City. Hank Bauer allegedly starts the fight by hitting a patron, although Bauer denies it. The Yanks fine Whitey Ford, Bauer, Yogi Berra, Mantle and Martin $1,000 each and Johnny Kucks $500.
