Ernie Els came from three strokes behind with five holes remaining to win the end-of-season PGA Grand Slam of Golf by one shot in Bermuda on Wednesday.
The smooth-swinging South African rattled up three consecutive birdies from the 14th on the way to a two-under-par 69 on the picturesque Port Royal Golf Course in Southampton.
That gave Els a 36-hole total of five-under 137, one better than first-round leader David Toms of the United States who closed with a 71.
U.S. Open champion Graeme McDowell of Northern Ireland battled to a 73 to finish at three over, level with U.S. PGA Championship winner Martin Kaymer of Germany (71).
The elite Grand Slam event, billed as "the most exclusive tournament in golf," traditionally brings together the winners of the year's four majors.
Els and Toms were late replacements in the four-man field for U.S. Masters champion Phil Mickelson and British Open winner Louis Oosthuizen.
American Mickelson opted not to play and South African Oosthuizen pulled out because of an ankle injury.
