DeLaet had always enjoyed playing Harbour Town Golf Links, Pete Dye's sneaky little layout with its narrow fairways and smallish greens. But the Canadian had not posted the scores to match how good he feels when he's here - until this week in going 65-67.
Donald has finished second or third in six of his last eight appearances at Hilton Head - and is position for another strong showing. He chipped in on the 18th hole to catch DeLaet.
Poulter and Simpson each shot 68.
