A final round of eight-under 64 at the TPC Kuala Lumpur has helped Justin Thomas to his second successive CIMB Classic title.
The American had to overturn a four-shot deficit to retain the trophy, capitalising on Anirban Lahiri's poor final-round display as he quadruple-bogeyed on the third hole.
Lahiri dropped three more shots across the course of the day, allowing bogey-free Thomas to pounce and in the end ease to a three-shot victory with a 23-under total.
Still searching for his maiden PGA Tour title, Lahiri finished in a tie for third alongside Derek Fathauer, while a strong finish across the final two holes saw Hideki Matsuyama claim second.
Paul Casey ended in a tie for 21st in Malaysia, meanwhile, and fellow Englishman Ian Poulter was one shot better off in 17th.
