The United States clawed back into contention at the Presidents Cup on Saturday by dominating the afternoon foursomes, but late scrambling by the Internationals secured a 10-8 lead heading into the final day at Royal Melbourne. There were angry scenes earlier when Patrick Reed's caddie clashed with a spectator after the U.S. golfer, heckled for three straight days for his waste bunker penalty in the Bahamas, was beaten in the morning fourballs with Webb Simpson, their third successive defeat in the Cup. U.S. captain Tiger Woods asked the crowd to be "respectful" of his team, saying some fans had drunk too much alcohol and gone too far in their taunting.
