The World No 3 secured his 38th career victory after he returned early in the morning to complete his third round before closing with a final round two-over-par 74 at the Royale Jakarta Golf Club.
Englishman Westwood’s winning total of 16-under-par 272 meant he finished two shots ahead of Thailand’s Thaworn Wiratchant, with the Indian duo of Gaganjeet Bhullar and Shiv Kapur tied in third place.
