The 1951 World Series drain-cover injury
In Game 2 of the 1951 World Series, rookie Mickey Mantle pulled up on a fly ball to defer to center fielder Joe DiMaggio, caught his spikes on a drainage cover in the Yankee Stadium outfield and collapsed with a badly damaged right knee. Leavy uses medical records and expert opinion to argue the injury was far worse than diagnosed and never properly repaired. Mantle played the rest of his career on a compromised leg, so the numbers that made him a legend were produced by a body that was already failing.
