the majors are scheduled annually. Largest margins of victory Major championships have been won by a margin of nine strokes or greater on eight occasions. On a further eight occasions, majors have been won by a margin of eight strokes; they include the 2012 PGA Championship, which was played over the Ocean Course at the Kiawah Island Golf Resort, for which Rory McIlroy holds the PGA Championship record. Single round records The record for a single round in a major championship is 62 which was recorded by South African golfer Branden Grace in the third round of the 2017 Open Championship. Consecutive victories These are consecutive because there was no The Open Championship in 1871 and no PGA Championship in 1917 and 1918. Wire-to-wire victories Players who have led or been tied for the lead after each round of a major. Outright leader after every round At least tied for the lead at the end of every round Top ten finishes in all four modern majors in one season It was rare, before the early 1960s, for the leading players from around the world to have the opportunity to compete in all four of the 'modern' majors in one season, because of the different qualifying criteria used in each at the time, the costs of traveling to compete (in an era when tournament prize money was very low, and only the champion himself would earn the chance of ongoing endorsements), and on occasion even the conflicting scheduling of the Open and PGA Championships. In 1937, the U.S. Ryder Cup side all competed in The Open Championship, but of those who finished in the top ten of that event, only Ed Dudley could claim a "top ten" finish in all four of the majors in 1937, if his defeat in the last-16 round of that year's PGA Championship (then at matchplay) was considered a "joint 9th" position. Following 1960, when Arnold Palmer's narrowly failed bid to add the Open Championship to his Masters and U.S. Open titles (and thus emulate Hogan's 1953 "triple crown") helped to establish the concept of the modern professional "Grand Slam", it has become commonplace for the leading players to be invited to, and indeed compete in, all four majors each year. Even so, those who have recorded top-ten finishes in all four, in a single year, remains a small and select group. ^ Never won a
