Thomas Bjorn shot a superb final-round 65 as he powered to victory by two strokes at the Nedbank Golf Challenge in Sun City.

Bjorn began the day three shots behind long-time leader Jamie Donaldson but four birdies allied to two crucial back-nine eagles saw the 42-year-old Dane blast past the hapless Welshman for a deserved victory.

Bjorn was denied a faultless card after a bogey at the last, but it mattered little as the European Tour veteran finished on 20 under par, comfortably clear of Donaldson and Sergio Garcia, who also shot a final-round 65 to finish in a tie for second on 18 under.

Bjorn's win, his 15th on the European Tour, was the second of the day for golf's old guard after 49-year-old Miguel Angel Jimenez claimed victory in the Hong Kong Open earlier on Sunday.
