Northern Ireland's Rory McIlroy replaced Australia's Adam Scott as the world's top ranked golfer after winning the WGC-Bridgestone Invitational in Ohio.
The 25-year-old took the world number one ranking for the fifth time, replacing Scott, who had held top honours for 11 weeks.
The British Open champion carded a 66 on Sunday to finish at 15-under-par 265 for a two-stroke victory over Spain's Sergio Garcia at the Firestone Country Club in Akron, Ohio.
Scott tied for eighth at seven-under. He would have had to finish fifth or better to retain his top world ranking.
