Texan storms up the leaderboard at Justin Timberlake Open
Chad Campbell fired a second-round 62 to vault into a share of the half-way lead on 13-under-par with Troy Matteson at the Justin Timberlake Shriners Hospitals for Children Open in Las Vegas.
Campbell picked up seven birdies and an eagle during a blemish-free, nine-under effort at the TPC Summerlin.
Starting from the 10th, the Texan rolled in five birdies to reach the turn in 31 shots.
And he maintained the momentum on the way home with further birdies at the third and sixth before signing off in style with an eagle at the par-five ninth.
Campbell's fireworks were enough to move him to the head of the leaderboard alongside Matteson, who followed his opening 62 with a four-under 67.
A winner at the TPC Summerlin three years ago, Matteson has had six further top-10 finishes in his last 12 Fall Series events and is again revelling in the late-season schedule.
Memories
"I've always liked the fall, maybe it coincides with the start of school every year for me when I was in college," said Matteson, who recovered well from two bogeys during his front nine with four birdies after the turn.
"I wasn't much of a summer golfer. I didn't play good in the summer.
"It does give me a lot of confidence to know that when I was hitting it good, what I could get done, and hopefully I could do something similar this week."
Scotland's Martin Laird was again the only non-American inside the top 10 and was locked in a four-way tie for third place on 12 under with Ryan Moore, Bob Heintz and Matt Kuchar.
Tom Pernice Jnr, who shared the first-round lead with Matteson and Spencer Levin, shot a 69 to drop to 11 under, alongside Jim Furyk, PGA rookie Rickie Fowler and Scott Piercy.
The cut fell at four-under and claimed 73 victims, among them reigning champion Marc Turnesa, Anthony Kim, Rory Sabbatini, Brian Davis and David Duval.
