Pavin won 15 times on the PGA Tour, including the 1995 U.S. Open. He made eight birdies Friday and holds the lead at the end of a round for the first time this year.
"I'm trying to play a little bit better and did some really good work the last few days here," Pavin said. "I really felt a lot more comfortable on the golf course today than I have in a long time."
Those tied for sixth at 67 included J.L. Lewis, Peter Senior, Rod Spittle and Jeff Sluman.
Only seven players who have led or co-led a tournament after the opening round this year have gone on to win the event.
