Their 63s matched the course record at Willow Creek Country Club. Mark Hensby was the first to post 63 here in 2000, while Joe Daley and David Sutherland in 2001 and Scott Gump in 2003 later matched the record.
Todd Demsey and Curtis Malm are one stroke behind the leaders at minus-7. Edward Loar and Tom Scherrer share fifth at 6-under-par 65.
Lile did his damage in spurts in the opening round. He ran home three straight birdie chances from the first. Around the turn, Lile birdied three in a row from the 10th to jump to minus-6.
The 30-year-old drained a 7-foot birdie putt at the 16th to move within one of Langham. Lile's tee shot at the par-3 18th stopped 20 feet from the hole. Not to worry, he sank that birdie putt to grab a share of the lead.
Lile is playing here this week since he failed to qualify for the FedEx Cup playoffs on the PGA TOUR.
'It is a comfort level. Knowing the town I am coming to and the course I am coming to, I think that is something I've had a hard time getting used to,' said Lile of his time on the PGA TOUR this year. 'Once you get used to things at events, you can build on that comfort level.'
Langham was steady throughout his round. He birdied every other hole from the first to the seventh. After three straight pars around the turn, Langham birdied the 11th and 12th to get to 6 under.
The two-time winner on the Nationwide Tour stumbled to a bogey on the par-four 14th. Langham caught fire down the stretch though. After birdies on 16 and 17, he converted a seven-foot birdie putt at the last to share the lead and the course record.
'I have played here before and struggled with the adjustment to the altitude since I'm used to playing at sea level all the time,' Langham admitted. 'Today, I was pretty spot on with the distances and I rolled my putter really well. That is a good combination.'
John Riegger, who won the LaSalle Bank Open earlier this year, and Justin Bolli, the Northeast Pennsylvania Classic winner, both carded rounds of 5-under 66. They were joined in a share of seventh by Chris Baryla, Jeff Klauk, Vance Veazey, Chris Anderson, Ron Whittaker and Tim Wilkinson.
Fifteen more players are one short further back at minus-4.
