Bernd Wiesberger fired a 5-under-par 67 on Sunday and won the Indonesian Masters by a single stroke over Ernie Els.
Wiesberger and Els began the final round one shot back of Daisuke Kataoka, but the Austrian carded just one bogey against an eagle and four birdies to finish at 15-under 273 and capture the Asian Tour victory.
Els birdied his final hole at Royale Jakarta Golf Club to wrap up a final- round 68 and end alone in second place.
Kataoka, of Japan, was undone by a pair of bogeys and carded a 70 -- good for a solo third finish at 13-under.
Thailand's Thongchai Jaidee (69) took fourth place at minus-10, while Angelo Que (70), Ryan McCarthy (70) and Joong kyung Mo (71) tied for fifth at 8- under.
Wiesberger was even through seven holes Sunday before picking up back-to-back birdies starting at No. 8. Starting in the same group as the eventual victor, Els played his outward nine at 1-under, while Kataoka was even on the day at the turn.
Both Wiesberger and Els eagled the par-5 12th, and the former struck the decisive blow with a birdie on No. 16, which proved vital when the reigning Open champion birdied the last to finish a stroke back.
