Rory McIlroy returned to the top of the world rankings for the first time in more than two years by retaining his CJ Cup title in South Carolina.
The Northern Irishman claimed a one-shot win at Congaree Golf Club, shooting a four-under-par 67 to finish the tournament on 17 under.
American Kurt Kitayama also hit 67 on Sunday, and briefly drew level with McIlroy thanks to a birdie at the 12th.
However, McIlroy made three straight birdies of his own to pull clear and claim his 23rd PGA Tour win.
