Australian golfer Cameron Smith is one shot off the lead at the halfway mark of the US PGA Tour event in San Antonio, Texas.
Smith shot a seven-under-par second round of 65 to be a shot behind joint leaders Tony Finau and Bud Cauley, heading into the weekend.
Long-hitting Finau stumbled at the final hole to fall back into a share of the second-round lead with fellow American Cauley.
Finau, buoyed by an eagle at the par-four 11th on Friday (Saturday AEST), looked set to enjoy sole possession of the lead at the end of the day until he bogeyed the par-five 18th, though he still carded an excellent seven-under-par 65 at TPC San Antonio.
The one-time PGA Tour winner joined Cauley (66) at eight-under 136, with Australian Smith in a group of three players one shot behind.

Smith enjoyed his fair share of good breaks in his 65.
"It all fell into place," he said. "Everything I hit, whether it was a rubbish shot or a good shot, went close to the hole. My short game was really good. I think I had three chip-ins."
Cauley was upbeat after hitting the front in his quest for a breakthrough victory on the PGA Tour, after previously finishing third on three occasions.
"I hit it a little better yesterday and didn't quite convert on some of the putts. Today I putted really well," he said.
"It was windy out there. I knew I was going to miss some greens and I was able to hit some good chips."
Last year's PGA Championship winner Jimmy Walker, who was recently diagnosed with Lyme disease, also moved into contention at his hometown event, three strokes behind.
