Ian Poulter and Mark Hubbard set the pace for good scoring through a brief spell of rain at Hilton Head. Jordan Spieth was pleasantly surprised to join the chase Thursday in the RBC Heritage.Poulter holed a 30-foot birdie putt on the 17th hole and finished with a 5-iron to 4 feet for another birdie that capped a 7-under 64, a round without a bogey but not without flaws.
