Luke Donald won a duel for No. 1 with a playoff victory over fellow Englishman Lee Westwood at the BMW PGA Championship in Virginia Water, England.
Donald, second behind Westwood entering the tournament, birdied the par-5 18th in the playoff, hitting his approach within 5 feet before Westwood's wedge shot spun off the green and into the water hazard.
Donald closed with a 1-under 70 to match Westwood (68) at 6-under 278 on Wentworth's West Course.
Donald joined Westwood and Nick Faldo as the only Englishmen to hold the No. 1 spot since the ranking was introduced in 1986. The victory was Donald's second in stroke play in five years. He won the European Tour's Madrid Masters last year. In February, he won the World Golf Championships-Match Play Championship in Arizona.
Donald missed two previous chances to become No. 1, losing to Ian Poulter in the World Match Play final last week in Spain and falling to Brandt Snedeker in a playoff at The Heritage on the PGA Tour in April.
England's Simon Dyson had a 68 to finish third at 4 under.
Byron Nelson Championship — Keegan Bradley won for his first PGA Tour victory, parring the first hole of a playoff with Ryan Palmer.
Bradley, the nephew of LPGA Tour great Pat Bradley, sank a 2-foot par putt at the 419-yard 18th hole in the playoff. Palmer's approach went into the water and he made a bogey.
About an hour earlier, Bradley finished his closing round of 2-under 68 with a par at No. 18, dropping into a squat and hopping a few times in frustration when his 10-foot birdie chance slid by the hole.
Palmer (72) and Bradley finished at 3-under 277, the highest winning score on the PGA Tour this year. It was the fifth playoff in six weeks. The PGA Tour rookie's aunt won 31 tournaments, including six majors. The first victory for the Vermont native who played at St. John's came nine days before his 25th birthday.
Ryuji Imada (71) and Joe Ogilvie (70) finished a stroke back at 2 under. Imada bogeyed three of his last four holes after getting to 5 under. There were brutal scoring conditions the last three days at TPC Four Seasons particularly for both weekend rounds when the wind was sustained at 25 mph with gusts howling near 40.
Teenage amateur Jordan Spieth had a rough finish. The 17-year-old player closed with two double bogeys and two bogeys for a 77 to finish at 6 over — 10 strokes higher than he shot last year at TPC Four Seasons.
Brazil Cup — Colombia's Mariajo Uribe won the LPGA Tour event in Rio de Janeiro, closing with a 6-under 66 in rainy conditions for a one-stroke victory over Lindsey Wright in the 36-hole exhibition tournament.
Uribe birdied five of the first seven holes on the Itanhanga Golf Club course and had two more birdies and a bogey on the back nine before closing with four straight pars.
Wright, from Australia, had her second straight 68. Sweden's Maria Hjorth (67) was third at 7 under. First-round leader Heather Bowie Young (72) and Sarah Jane Smith (68) tied for fourth at 6 under.
