BEIJING, Aug. 15 (Xinhua) -- Talita Antunes and Renata Ribeiro of Brazil earned a berth in top eight of beach volleyball tournament at the Beijing Olympics on Friday.

    They came from behind to beat Susanne Glesnes/Kathrine Maaseide of Norway in three sets (12-21, 21-19,15-13).

    "I'm not so satisfied with my performance in the match. It's a so important match but we're a little tired," commented Ribeiro on their early setback.
