The modern definition could not be applied until at least 1934, when the Masters was founded, and still carried little weight in 1953 when Ben Hogan won the Masters, U.S. Open, and Open Championship. That year, it was impossible to win all four as the PGA Championship preceded and overlapped with the Open Championship; the PGA's 36-hole match play semifinals and finals near Detroit were the same days as the mandatory 36-hole qualifier at Carnoustie in Scotland for the Open Championship; the only way to compete in both events was to lose an early match at the PGA. Hogan is the only player to have won the Masters, U.S. Open, and Open Championship in the same calendar year.
