By Steve Keating RIO DE JANEIRO (Reuters) - The U.S. women's basketball team wrapped up Olympic preliminary round play in familiar blowout style by routing China 105-62 on Sunday, storming into the quarter-finals unbeaten and on course for a sixth straight gold medal. Serbia also secured a spot in the last eight, grinding out a 95-88 victory over winless Senegal, while Spain beat Canada 73-60 in the final Group B clash to set the matchups. Group B top-seeded United States have their next opponent, 16th ranked Japan, in their crosshairs while Serbia get unbeaten Australia, Group A's top seed.
