US lead Presidents Cup

The United States will take a three-point lead over the International team into the final day's 12 singles matches after extending their Presidents Cup advantage on day three in San Francisco.

Fred Couples' American team led Greg Norman's Internationals by 12.5 to 9.5 at Harding Park after a day of five foursomes and five fourballs matches which saw the world's top three players - Tiger Woods, Phil Mickelson and Steve Stricker - lead from the front in both sessions.
