Rogers and Dalhausser lost the first set, 21-17, and fell behind Paolo Nicolai and Danielle Lupo, 12-7, in the second. The Americans tied it 19-19 but lost the final two points and were eliminated when Rogers' spike was blocked back into him by the 6-foot-8-inch Nicolai.
Americans Jennifer Kessy and April Ross beat Switzerland's Simone Kuhn and Nadine Zumkehr.

Sergei Martynov of Belarus set a world record in the men's 50-meter rifle prone and won the gold medal.

Andy Murray of Britain clinched at least a silver medal and advanced to the Olympic final by beating No. 2-seeded Novak Djokovic of Serbia, 7-5, 7-5.
With the win, the No. 3-seeded Murray earned a rematch Sunday against No. 1 Roger Federer, who outlasted Juan Martin del Potro of Argentina, 3-6, 7-6 (5), 19-17.
Djokovic will play del Potro on Sunday for the bronze.
