(Reuters) - 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 on Sunday.
McIlroy, 25, 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.
