Playing in the final group of the day, Singh and Daly duelled through the final round.

Singh withstood a sizzling start by Daly, who played the first four holes in five under, and took the lead for good with a birdie on the 16th.

It was the fourth victory of the year and second Buick Open title for Singh, who signed for a five-under-par 67 and completed 72 holes at 23-under 265.

Daly, who ended a nine-year drought earlier this year at the Buick Invitational, posted a 66.

Tiger Woods, still without a win in a strokeplay event this year, tied for third with Paraguay’s Carlos Franco at 21-under.

Woods could not catch Singh despite shooting a 66 in each of the last two rounds.

Nursing a one-shot lead, Singh pulled his drive on the last way right under a tree, then appeared to be in more trouble when he left his second shot in the deep rough.

But despite facing another tough lie, he came through with a spectacular third shot, getting it to stop on the green just four feet from the pin.

Singh missed the par putt, sliding it just past the hole.

Daly had an opportunity to force a play-off, but also stroked his four-foot par putt past the hole. It was his first bogey in 31 holes.
