The Heritage 2011 Scoring Update: Luke Donald Leads After Third Round, Could Earn World No. 1 Ranking

Luke Donald's third round one-under 70 at Hilton Head gives him the lead entering Sunday's final round at The Heritage. But it's also got him in great position to claim the title of world's top-ranked golfer.

Donald was solid coming in, with eight pars and one birdie on his back nine, in compiling his 70. He sits at 11-under after three rounds at Hilton Head, one shot clear of defending champion Jim Furyk and two shots ahead of Brendan de Jonge and Scott Verplank.

Donald could move to No. 1 in the World Golf Rankings if he holds on for a victory on Sunday. He would supplant current world No. 1 Martin Kaymer. If Donald doesn't win The Heritage, Kaymer could still lose his perch should Lee Westwood win the Indonesian Masters.

Donald has been one of the world's hottest golfers in 2011, winning the Accenture Match Play and tying for fourth at The Masters.
