Justin Rose has moved to World No.1 for the first time in his career despite losing a playoff to Keegan Bradley at the BMW Championship.
Bradley defeated Rose at the first extra hole after the pair could not be separated on 20-under par.
The win marks the American's first triumph in six years and the fourth of his PGA Tour career.

Rose, however, takes consolation from becoming the 22nd player to reach World No.1 since the Official World Golf Ranking system came into force back in 1986.
He also becomes just the fourth Englishman to reach the summit, joining Sir Nick Faldo, Lee Westwood and Luke Donald to perform the feat.
Billy Horschel and Xander Schauffele finished one stroke off the pace on 19-under par, with Rory McIlroy a further shot back.
Tiger Woods started brightly in the final round but a couple of mistakes on the back nine put paid to his chances and he finished in a tie for sixth on 17-under par.
Tony Finau picked up yet another top-10 finish on 16-under par and he will now likely receive Jim Furyk's final US Ryder Cup wildcard pick.
