A three-way tie for the lead has emerged with Paul Goydos, Charles Warren and Spencer Levin all at -7.
Goydos and Warren are done for the day and Levin is on his last hole at 18.
"The greens were unbelievable today," Warren said after his round. "I think the way the course is playing there will be low scores all week. I wouldn't be surprised if someone goes below -7 by the end of today."
Greg Chalmers and Tag Ridings, both done for the day, are tied for fourth at -6.
