Vijay Singh and Carlos Franco shot a 7-under 47 in wind gusting to 20 mph on the Top of the Rock par-3 course to get to 19-under 145, a stroke ahead of the teams of David Toms-Steve Flesch and Paul Broadhurst-Kirk Triplett.
John Daly and Michael Allen shot an 8-under 46 on the Top of the Rock par-3 course with wind gusting to 15 mph and the temperature only in the high-50s at Big Cedar Lodge. They had three birdies on the front nine in alternate-shot play and added five more on the back in better-ball play to get to 13 under.
Zach Johnson made an 8-foot par putt on the 13th hole of the opening round to stay at 2 under. He followed with a big drive, a hybrid into 12 feet and an eagle. Johnson was on his way, and he kept right on going Friday to a 7-under 65 and a share of the early 36-hole lead with Ryan Moore.
Using a new putter, Park birdied four consecutive holes on the back nine before a bogey on the par-4 17th. She quickly recovered and rolled in birdie putts on the second and fifth holes to finish off her round.
