Leader Gotterup goes on birdie-blitz, Endycott falters

Chris Gotterup birdied the final four holes and six of the last eight for a 7-under 64 to grab a one-stroke lead over Robert MacIntyrey midway through the PGA Tour's inaugural Myrtle Beach Classic.

After making two birdies and a bogey on the front nine at Dunes Golf & Beach Club, Gotterup played the back nine in 6-under 30 in windy conditions on Friday.

He made a 50-foot birdie putt on the par-3 17th and a 17-footer from the fringe on the par-4 18th.

"Really just executing shots pretty solidly down the stretch there," said Gotterup, the 24-year-old former University of Oklahoma player who is winless on the PGA Tour. "It got pretty windy, so definitely a good finish."

He had a 12-under 130 total.

"It's a little tricky when you've got the wind going on some cross-wind holes, but I definitely can take advantage on a couple holes with some length," Gotterup said. "Obviously, you've got to hit it straight to do that."

MacIntyre, the Scot who was tied for the first-round lead with Beau Hossler after a 64, shot a 67.

"It's been really good," said MacIntyre, also seeking his first tour victory. "I think it's difficult to back up a good round yesterday. Felt like I done that really well."

Jorge Campillo of Spain had his second 66 to get to 10 under. Hossler (69), Alex Smalley (65), Davis Thompson (68) and Alistair Docherty (68) are at nine under.

The Australian charge fell away in the second round with Harrison Endycott, who was just two behind the overnight lead, adding a 75 to his opening 66.

The Sydneysider finished at one-under alongside compatriot Aaron Baddeley (71, 70), to miss the cut by one.

The tournament is being held opposite the Wells Fargo Championship, a signature event in Charlotte, North Carolina.

The Myrtle Beach winner will get a spot in the PGA Championship next week, but not in the Masters or a guaranteed spot in the remaining two $20 million ($A30m) signature events.
