Sergio Garcia leapfrogged Phil Mickelson to become world number two after edging out Ryder Cup team-mate Oliver Wilson in a play-off to win a thrilling rain-affected HSBC Champions in Shanghai.

The Spanish golfer carded a final round four-under-par 68 to join overnight leader Wilson at the top of the leaderboard after the Englishman shot a fourth round of 70 on the fifth day at Sheshan International Golf Club.

In the play-off, Garcia birdied the second extra hole to claim his second win in three weeks after triumphing at the Castello Masters on his home course at the end of October.

With the win, Garcia claimed a career-high in the world rankings behind Tiger Woods, while the €650,000 first prize sends the 28-year-old top of the inaugural Race to Dubai.

Ryder Cup rookie Wilson, who earned his trip to Valhalla even through he has yet to win a title, earned his fifth runner-up finish of 2008.

"It feels great," said Garcia after claiming his eighth European Tour victory. "I am so proud, to win and become world number two, it's been a great week."

SAS Masters winner Peter Hanson shot a six-under-par 66 to share third place alongside former US Open champion Geoff Ogilvy, who birdied the final hole for a second consecutive 70, at 13-under.

Sweden's Henrik Stenson (71) finished fifth at 11-under, with South Africa's Charl Schwartzel (70) and Australian Adam Scott (70) a further shot off the pace.

Defending champion Mickelson finished on nine-under after a final round of 73 which included a double-bogey on the 15th.

Dubliners Pádraig Harrington and Peter Lawrie finished in a tie for 11th spot and a cheque for €67,500 after both shot fine four-under-par 68s in the final round to finish on seven-under.

Graeme McDowell (72) and Damien McGrane (73) took a share of 16th on four-under, while Darren Clarke posted a final round of 79 to finish alongside David Howell in a tie for 58th spot.
