In the modified Stableford event, players receive eight points for double eagle, five for eagle, two for birdie, zero for par, minus-one for bogey and minus-three for double bogey or worse.
Ogilvy, the Australian who won the 2006 U.S. Open, had seven birdies and two bogeys in a 12-point round at Montreux to push his total to 35. He's making his first appearance in the event since 2002 after failing to qualify for the World Golf Championship-Bridgestone Invitational.
Nick Watney, the leader after each of the first two rounds, was tied for second with Jason Allred. Watney scored six points, and Allred had 14.
