Las Vegas, NV (SportsNetwork.com) - Andrew Putnam carded a 6-under 65 on Friday and he moved into a share of the lead with Russell Knox after two rounds of the Shriners Hospitals for Children Open.
Knox posted a 4-under 67 and the duo ended 36 holes at 10-under-par 132.
In his fourth career PGA Tour start, this marks the first time Putnam has made the cut. He earned his 2014-15 PGA Tour card via the Web.com Tour, where he had a win and a runner-up finish among his five top-10 finishes in 2014. Knox lost in a playoff at the Honda Classic last March, but had just two other top-10 finishes in the 2013-14 PGA Tour season.
Tony Finau (65) and Andrew Svoboda (67) are tied for third place at minus-9.
Spencer Levin and George McNeill both fired 8-under 63s to share low round of the day honors. They jumped to 8-under-par 134 and were joined in fifth at TPC Summerlin by defending champion Webb Simpson (65), Wes Roach (67), Ben Martin (66), Scott Piercy (67), Bo Van Pelt (68) and Martin Laird (70), who shared the first-round lead with Stewart Cink.
Cink stumbled to a 4-over 75 and tumbled into a tie for 45th place at minus-3.
Putnam found the right rough off the tee at the third and that led to an early bogey. He came right back with a 17-foot birdie putt on No. 4.
He dropped his approach shot to eight feet at the sixth and converted that putt to move to minus-5. After a pair of pars, Putnam reached the par-5 ninth in two shots and he 2-putted for birdie from 39 feet out.
Putnam made it two in a row as he drained a 31-foot birdie try at the 10th. He moved within one of the lead thanks to birdies on the two par-5s, Nos. 13 and 16. Putnam capped his round with a kick-in birdie at the last as his approach shot stopped inside two feet.
"I had a good day today, pretty sweet round. I had a bogey early on, but ever since then I felt pretty good," Putnam said. "I wasn't driving it that well for a few months, but I've been working on getting the ball to stay on the right line and tightening it up a little bit more, trying to move the ball both ways, getting a little tighter off the tee."
Knox drained a 10-foot birdie putt at the first, but he 3-putted for bogey on the second and failed to get up and down for par on No. 3. The two bogeys dropped him to minus-5.
After three pars in a row, Knox started his climb up the leaderboard with a 22-foot birdie putt at the seventh. He got up and down for birdie on the ninth to make the turn at 7-under.
Knox parred the first three holes of the back nine. He tapped in a short birdie on the par-5 13th. At the short 15th, Knox drove the green and 2-putted for birdie.
At the last, Knox converted a 13-foot birdie try to post 10-under.
"I was pleased with that today. I didn't get off to the greatest start, but stayed patient and got some good results on the back nine," Knox said. "I got a bit worried because I was all over the map. I didn't feel real good with my swing, and I knew if I just made some pars, eventually something would click, and I made a couple putts, which really settled me down."
