(CNN) -- American trio Tom Pernice, Troy Matteson and Spencer Levin are locked in a three-way tie for the lead at the end of the first round of the Justin Timberlake Shriners Hospitals for Children Open at TPC Summerlin in Las Vegas.
Pernice had a blemish-free round to share the lead after the first round at TPC Summerlin in Las Vegas.
The 50-year-old Pernice, a winner on the Champions Tour at the SAS Championship last month, laid down the gauntlet with a bogey-free nine-under-par 62 and was joined in a share of the overnight lead by Matteson, the 2006 winner, who fired 10 birdies and an eagle.
"I got off to a really good start, which was nice, and continued to have a really good round," Pernice told the official PGA Tour Web site.
"Good, quality iron shots first really set it up. The iron shots really were the key. And the conditions are obviously perfect here."
Levin joined the other two at the top of the leaderboard late in the day, seven birdies and an eagle ensuring the 25-year-old Californian enjoyed a career-best round on the PGA Tour. His previous best, a 63, came earlier this year in Milwaukee.
Scotland's Martin Laird -- the only non-U.S. player inside the top 12 -- and Bob Heintz are locked in a tie for fourth place a shot further back on the leaders while three-time Las Vegas winner Jim Furyk recovered from two early bogeys to fire a 64 and claim a share of sixth place alongside Scott Piercy.
Tim Petrovic, Jeff Klauk, Kirk Triplett, Briny Baird and Robert Garrigus are all a further stroke behind after six-under-par rounds of 65.
