Canadian Graham DeLaet eagled the par-4 ninth hole and shot a four-under 67 for a share of the second-round lead with Englishman Luke Donald at the US PGA Tour's RBC Heritage tournament.
Donald also had a 67 to match DeLaet at 10-under 132, two ahead of England's Ian Poulter and American Webb Simpson.
DeLaet had always enjoyed playing Harbour Town Golf Links, Pete Dye's sneaky little layout with its narrow fairways and smallish greens.
But DeLaet 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 past eight appearances at Hilton Head - and is position for another strong showing.
