This Day in Golf History: August 6
Like Arnold Palmer, Tom Watson didn’t win the PGA, which would have given them a career Grand Slam. On this date in 1978 at Oakmont Country Club, John Mahaffey rallied from seven shots back with 14 holes to play to tie Watson and Jerry Pate, and then he won on the second hole of a sudden-death playoff. Watson had been in control during regulation, but his perfect drive on 10 finished in a sand-filled divot hole and he ended up making double bogey, and he lost control of the outcome.
