NISSAN LEADERBOARD US unless stated -9 C Campbell, A Scott (Aus) -8 D Clarke (NI), B Davis (Eng) -7 C Montgomerie (Sco), JL Lewis

Scott, 24, parred the first extra hole to edge out Campbell after the tournament was reduced to two rounds.

The proposed third round was abandoned on Monday morning because the Riviera Country Club was saturated.

Britons Brian Davis and Darren Clarke missed the play-off by one stroke while Colin Montgomerie was one shot back.

Scott, who fired a five-under-par 66 on Sunday, and Campbell, after a 65 on Friday, had finished the 36 holes level on nine-under 133.

Campbell missed a four-foot putt for a bogey five at the 475-yard 18th to hand the $864,000 to Scott, who moves up to seventh in the world.

"It was tough for Chad to have two days off and then come out, but a win is a win," said Scott.

England's Davis, winner of the US Tour qualifying school in December, was in two minds about the outcome.

I was playing great and I could have nicked the title England's Brian Davis

"It's a happy mood and a bad mood rolled into one," Davis told BBC Sport.

"Obviously I'm happy with tied third. It was a great week for me.

"But the flip side is I would have loved to have gone out for the third round because I was playing great and I could have nicked the title."

The Nissan is the first PGA Tour event since the 1996 Buick Open to crown a champion after just two rounds.

And the victory will not hold official status - meaning the winner will not gain the usual two-year exemption or a place at the season-opening Mercedes Championship in Hawaii.

The tournament started hitting problems on Friday when it suffered a four-hour delay.

Saturday's play was totally washed out and the second round was not completed until 2.30pm on Sunday.

Montgomerie lost valuable ranking points

The tournament's curtailment meant good and bad news for Clarke, Davis and Montgomerie.

They were still paid full money for their rain-abbreviated week - $278,400 for Clarke and Davis, $182,400 for Montgomerie - and it also counts towards the US money list.

But they will get only 75% of the world ranking points on offer, of prime importance to Montgomerie in his quest to qualify for the first two majors of the season.

The Scot is currently in 62nd and needs to be in the top 50 by the end of March to qualify for the Masters.

His next event is next week's Dubai Desert Classic, whereas Clarke will look for a repeat of his 2000 Match Play victory.

Davis moves on to the Chrysler Classic in Tucson starting on Thursday.

Tiger Woods, who needed to finish no worse than outright third to reclaim the world number one spot from Vijay Singh had to settle for a share of 13th.
