SAN FRANCISCO - Australia's Peter Senior shot an 8-under 63 on Thursday to take a one-stroke lead in the Champions Tour's season-ending Charles Schwab Cup Championship.
Senior had nine birdies, an eagle and three bogeys at TPC Harding Park.
David Frost shot 64, missing a short putt on the 18th hole. Fred Couples was third at 65, and Mark O'Meara had a 66. Bernhard Langer, Steve Elkington and Duffy Waldorf shot 67.
Charles Schwab Cup points leader Kenny Perry topped the group at 68. Perry entered the event 612 points ahead of second-place Langer. If Langer wins the tournament, Perry needs only to finish fifth or better take the season title and $1 million annuity.
