Silverman had 10 birdies and a bogey on Tahoe Mountain Club's tree-lined Old Greenwood layout on Thursday for a two-point lead over Kelly Kraft.
"This place is gorgeous," said Silverman, the 36-year-old Canadian seeking his first PGA Tour victory. "Really like this golf course."
Players receive eight points for a double eagle, five for eagle and two for birdie. A point is deducted for bogey and three for double bogey.
"You try to put the points out of your head and just focus on making birdies and adding up your score normal," Silverman said. "You get rewarded for birdies and the points kind of take care of themselves. That's how you try to do it."
Kraft eagled the par-5 third and had seven birdies and two bogeys.
"I was just in scoring and the guy told me what I shot, and I was like, 'I have no idea what I shot. I just know I had 17 points.'" Kraft said. "You're kind of just trying to make birdies the whole time."
Nate Lashley was third at 15, and Sam Ryder and S.H. Kim had 14. Lorenzo Scalise of Italy, one of 50 European tour players in the field, was at 13 with Patrick Fishburn and Vince Whaley.
Jason Scrivener scored nine points and is the best placed Australian in a tie for 30th.
With three weeks left in the FedEx Cup regular season, Lashley is 97th, Silverman 100th, Kim 110th, Ryder 120th, Fisburn 139th, Whaley 167th and Kraft 172nd. The top 70 will advance to the playoffs.Â
Taylor Pendrith, at No.36 the highest-ranked player in the FedEx Cup in the field, had a 12-point round. The Canadian won at Colonial in May for his first PGA Tour title.
