Bobby Jones, trying to win the the third leg of the Grand Slam, leads by three when he slices his tee shot on the par-3 17th in the final round. No one sees precisely where it lands; many felt Jones should have taken a lost-ball penalty and returned to the tee. But Prescott Bush, the USGA referee (and grandfather of President George W. Bush), rules Jones' ball had buried in a dried swamp, declaring it a parallel water hazard and allows Jones to take a one-shot penalty and drop near the green. He makes double-bogey 5, then birdies the last hole to win by two.
