June 18 (UPI) -- Ian Poulter and Mark Hubbard were tied atop the leaderboard after each shot a 64 in Thursday's opening round of the RBC Heritage at Harbour Town Golf Links in Hilton Head, S.C.
Poulter holed a 30-foot birdie putt on No. 17 and recorded another birdie on the final hole to cap his 7-under 64 in the first round. Hubbard, who had an eagle on hole No. 2 and five birdies, kept his score together with two par putts at the end.
Hubbard and Poulter held a one-shot lead over Sebastian Munoz, Viktor Hovland, Michael Thompson, Webb Simpson, Dylan Frittelli, Brice Garnett and Ryan Palmer, with that group finishing 6-under par for a share of third.
Jordan Spieth -- who started on the back nine -- got off to a rocky start Thursday, but the three-time major champion clawed out of a big hole with a remarkable stretch of birdies on the front nine.
Three holes into the tournament, Spieth carded a triple bogey after bouncing a shot off a tree. He remained two strokes over par through his first nine holes until bouncing back with seven birdies -- including six in a row -- on his second nine.
"All of a sudden, I'm three over through three, and you start to see guys going two under through two, two under through three early. It's not a great feeling," Spieth said.
Spieth's recovery put him at 5-under par and in a tie for 10th with Tony Finau, Mackenzie Hughes and Matthew NeSmith, among others.
Rory McIlroy -- playing at Harbour Town Golf Links for the first time since 2009 -- opened the tournament with a 72, ending his streak of seven consecutive events in which he broke par in the first round. Brooks Koepka, Rickie Fowler and Bryson DeChambeau were among those at 4-under 67.
