At the inaugural Greenbrier Classic in 2010, Stuart Appleby shot 59 in the final round to win at 22 under. With favorable scoring conditions this week, there's already talk about surpassing that. On Thursday, the top eight scores produced just nine total bogeys.
"I believe you can get to at least 20 (under) this week," Gainey said. "It depends on how much rain we get and how much softer this course gets."
Lancaster's lone PGA Tour win came at the 1994 Byron Nelson Classic. He's won $83,000 in five Champions Tour events this year. With an early second-round tee time, he knew where he was heading after Thursday's round.
"To bed. Fifty-year-old guys don't want to play golf at 7:20 in the morning," he said.
Among those at 2 under were Bill Haas, coming off a win at Congressional last week, and Ryan Palmer, whose caddie is New Orleans Saints coach Sean Payton.
Phil Mickelson, playing for the first time since finishing second to Justin Rose at the U.S. Open, struggled to a 74. His tee shot on the par-5 17th landed in Howard's Creek and he three-putted for triple bogey. He also had five bogeys and four birdies.
A similar round on Friday would mean his third missed cut of the year and the third consecutive time he's failed to advance to weekend play at the Greenbrier Classic.
"I don't know what it is," Mickelson said. "I felt like I was playing really well heading in here. I don't play this course well. I don't know what the reasoning is. It's just given me problems the last few years."
