Paul McGinley lost his patience and blew up in the Hana Bank Vietnam Masters near Hanoi.

Just two shots off the lead with five holes to play, the Dubliner went on the attack and dropped four shots in just three holes down the stretch.

After a bogey at the 14th, McGinley made a seven at the par five 15th and then bogeyed the 16th before picking up a shot at the next.

He eventually shot a level par 72 to finish tied for fifth and five shots behind Thailand's Chapchai Nirat on seven under par.

McGinley said: "I got a little bit impatient at the end. I didn't putt very well.

"I took on some pins out there and I tried to force the error because I didn't feel like I was going to make those putts."

Nirat claimed a two-shot victory after a blistering finish at Hanoi Phoenix Golf Resort.

The Thai birdied three of his last four holes for a 67 to finish two strokes ahead of England's Simon Griffiths and compatriot Chawalit Plaphol to claim his second title of the year and a winner's cheque of US$79,250.
