Singapore – Italian teenager Matteo Manassero birdied the last hole to force a play-off with South Africa's Louis Oosthuizen at the $6 million Barclays Singapore Open on Sunday.

Manassero, 19, hit two huge shots to reach the green, and then two-putted from 60 feet to deny Oosthuizen an outright win with both players finishing four rounds on a total score of 13-under-par 271.

The play-off was set to extend a marathon final day after storms on Thursday and Friday meant the third round had to be completed on Sunday morning.

Oosthuizen had rounds of 70, 69, 65 and 67, and Manassero carded 70, 68, 64 and 69. – Sapa-AFP
