Pan began the day tied for 19th after a 69 at Cherry Hills on the first day of qualifying. He moved up 18 spots with his standout performance at the companion course at CommonGround.
"I'm hitting the ball great, driving well," Pan said. "Hitting irons well, and my long game is always good. I executed every shot well."
Meanwhile, Gary Nicklaus, the 43-year-old son of Jack Nicklaus and one of the oldest competitors in the amateur, shot a 74 at Cherry Hills for a two-day score of 4-over 145, leaving him in a tie for 117th place and out of match play midway through the final round of qualifying.
Nicklaus, a former PGA tour pro who was reinstated as an amateur in 2007, had qualified for the Cherry Hills event after missing the 1990 event at the same course because of a heart ailment. He was an up-and-coming 20-year-old when he came down with pericarditis on the eve of the 1990 amateur, forcing him to undergo a week of treatment in the hospital instead of competing on the golf course.
Also advancing to match play at 3-under-par 138 were two 2011 USA Walker Cup Team members: Chris Williams, 21, of Moscow, Idaho, who won the 2012 Western Amateur and is ranked No. 1 in the world, and Jordan Spieth, 19, of Dallas, the low amateur at the 2012 U.S. Open, who is ranked No. 3 in the world by the World Amateur Golf Ranking that is jointly administered by The R&A and the USGA.
