Which golfer, the first to complete a career Grand Slam - winning the four Majors at some time during his career, achieved a hole-in-one in the 1973 Open at Troon at the age of 71?
Grand Slam (golf) definitive answer. Only five golfers have won all four of golf's modern majors at any time during their careers, an achievement which is often referred to as a "Career Grand Slam": Gene Sarazen, Ben Hogan, Gary Player, Jack Nicklaus, and Tiger Woods. Woods and Nicklaus have won each of the four majors at least three times. A number of dominant players of their eras have failed to achieve the Career Grand Slam because of their inability to win a particular major. Sam Snead and Phil Mickelson (through 2018) failed to win a U.S. Open; Arnold Palmer, Tom Watson, and Jordan
The Open Championship Championship in 2008. In 2009, 59-year-old Tom Watson turned in one of the most remarkable performances ever seen at The Open. Leading the tournament through 71 holes and needing just a par on the last hole to become the oldest ever winner of a major championship, Watson bogeyed, setting up a four-hole playoff, which he would lose to Stewart Cink. In 2013, Phil Mickelson won his first Open Championship at Muirfield. His victory meant that he had won 3 of the 4 majors in pursuit of the career grand slam, just needing the U.S. Open, where he has finished runner-up
