Martin was nearly undone by a triple-bogey seven at the 17th hole but the 24-year-old finished in typically thrilling fashion by going for the island green in two on the par-five 18th and claiming a birdie to finish with a 70 and an 11-under-par total of 277.

The last player to retain a title on the European Tour was Ireland's Padraig Harrington who won the British Open at Carnoustie in 2007 and at Royal Birkdale in 2008.

Dane Thorbjorn Olesen and South Africans Charl Schwartzel and Anthony Michael, who had led from day one, were joint second on Sunday on 279.
