There are horses for courses and then there is Luke Donald at Harbour Town. The former World No. 1 has racked up five top-3 finishes in his last five trips to Hilton Head Island.
Joining Donald atop the leaderboard is South African Branden Grace. Both the Kiwi and Englishman shot matching 5-under par 66s to start the week. Chasers after day one include current World No. 1 Jason Day, Matt Kuchar, David Lingmerth and Tony Finau who are all one shot back at 4-under par.
