BEIJING — Roger Federer has salvaged his bid for an Olympic medal, winning his doubles quarterfinal with fellow Swiss Stanislas Wawrinka against Leander Paes and Mahesh Bhupathi of India.

The Swiss pair beat the Indians 6-2, 6-4 on Friday, completing a match that was suspended at 1:15 a.m. because of rain and resumed 15 hours later.

Top-ranked Federer lost his singles quarterfinal to James Blake on Thursday.

Venus and Serena Williams, both of whom were eliminated in singles Thursday, also completed a suspended second-round doubles match and beat Ayumi Morita and Ai Sugiyama of Japan, 7-5, 6-2.
