LONDON (AP) — When temperatures dropped into the 60s for start of the first night session at Horse Guards Parade, the Olympic beach volleyball players said bye-bye to their bikinis.

Two-time defending gold medalists Kerri Walsh Jennings and Misty May-Treanor of the United States wore long-sleeved shirts on top of bikini bottoms for their 21-18, 21-19 victory over Natalie Cook and Tasmin Hinchley, a match that started at 11 p.m. Saturday when the temperature was 63 degrees. The Australians wore long pants, with T-shirts under their bikini tops.
