Rory McIlroy suffered Sunday heartbreak for a second successive week as Italian Matteo Manassero won the Maybank Malaysian Open two days before his 18th birthday.
The Northern Irishman led by four going into the final round of the Masters at Augusta last week but blew his advantage by shooting eight-over-par.
His fade from prominence this weekend was less spectacular, letting slip a three-shot lead going into the final four holes of his partially-delayed third round on Sunday morning before ultimately finishing third, but questions will continue to be asked of the 21-year-old's mental strength following this latest setback.
Manassero demonstrated his fortitude to claim his second European Tour title following on from his victory at the Castello Masters last year.
The Italian was four-under-par in his final round, including an eagle three at the par-five 10th.
Frenchman Gregory Bourdy finished a shot off the lead after carding a final round 67.
