Defending champion Lee Westwood held off the rest of the field to win the Sun City Challenge by two strokes at the Gary Player Country Club on Sunday.
Westwood began the final day with a seven-shot lead after the course-record 62 he fired in the third round, but the Briton did not have the same sharpness to his game on Sunday.
However, the rest of the field could not capitalize, with second-placed Swede Robert Karlsson’s 68 being the best score of the fourth round, and Westwood could afford to bogey the last two holes for a win that was more convincing then the scoreline suggests.
Westwood’s final-round 73 saw him finish on 15-under 273 for the tournament, earning the world No. 3 the winner’s check of US$1.25 million in the 12-man invitational event.
The Englishman went through the front nine in two-under with birdies at the par-four sixth and par-five ninth holes as he reached the turn with a five-stroke lead.
Northern Irishman Graeme McDowell went to four-under for his round with a birdie at the par-five 10th, but his hopes took a dive with a double-bogey at the par-four 15th when his approach to the green went way down a bank.
