Fabrizio Zanotti clinched a second European Tour title, sealing the Maybank Championship with a final-hole eagle after Danny Willett faltered.
Paraguayan Zanotti carded a nine-under 63 in the final round at the Saujana Golf and Country Club in Kuala Lumpur, Malaysia on Sunday.
Zanotti finished at 19 under to win his first European Tour crown since the 2014 BMW International Open.
American David Lipsky (67) was a shot back in outright second, while Austrian Bernd Wiesberger (66) finished third at 17 under.
Masters champion and overnight leader Willett struggled in the final round, mixing four birdies with five bogeys in a one-over 73.
That saw the Englishman finish in a tie for fifth alongside China's Li Haotong (65).
Zanotti's round included seven birdies and an eagle, including picking up a shot at the 17th before his three at the par-five last.

Lipsky also birdied the 17th and needed another on the 18th, but he was unable to force a play-off.
Frenchman Alexander Levy made a good start to his round with four birdies on the front nine, but bogeys on par-four holes 10, 14 and 15 saw him end up fourth.
Anirban Lahiri (68) and Mike Lorenzo-Vera (69) were tied for seventh at 14 under, two shots ahead of Shubhankar Sharma (69) and Panuphol Pittayarat (71).
