Australia’s Rod Pampling made four birdies in five holes in a mid-round surge during the Byron Nelson Classic in Texas.
After starting his round with six consecutive pars, Pampling went on an impressive run, starting with a 2m birdie putt on the par-5 seventh.
The 47-year-old backed it up with longer birdie putts at the par-4 eighth and ninth holes.
Pampling also made a birdie at the par-4 11th before dropping a shot at the par-4 14th.
The veteran Queenslander is eight shots behind runaway leader, American Jason Kokrak.
Kokrak’s collection of four birdies on his outward nine was matched on the run home at TPC Four Seasons in a bogey-free round of 62.
He holds a five-shot lead over fellow American Billy Horschel who backed up an opening round 68 with a five-under par 65.
Jason Day had a promising round going until the par-five 16th hole when he lost his ball off the tee and took a double-bogey to finish at three-under, nine shots off the pace after carding a one-under 69.
Marc Leishman and Greg Chalmers will also be in action at the weekend after they both had rounds of 71 to be at one-under.
World No.1 Dustin Johnson is within striking distance after shooting a second consecutive three-under-par 67 to be six-under at the halfway mark of the tournament.
One man who will not be around for the weekend, though, is Jordan Spieth after he missed the cut following a bogey-laden 75.
It was on the par-5 16th where the real damage was done as he had to take three tee shots on his way to a nine after sending his first two attempts out of bounds.
Reigning champion and recent Masters winner Sergio Garcia is 10 shots off the lead despite a superb round of 65, recovering from what was a poor first round.
