(CBS/AP) It's going to be an all-American beach volleyball final at the London Olympic Games.
Misty May-Treanor and Kerri Walsh Jennings will play fellow Americans April Ross and Jennifer Kessey for the gold medal on Wednesday night.
Walsh Jennings and May-Treanor advanced to their third consecutive Olympic gold medal game with a 22-20, 22-20 victory over China.
"We want to seal the deal that we're the best team that's ever happened," Walsh Jennings said after the win on Tuesday night. "Misty has changed my life. I just love her. I want to win tomorrow for us."
A few hours later, Kessy and Ross beat the top-seeded Brazilians in a persistent rain. They rallied from a first-set loss and a four-point deficit in the second to beat reigning world champions Juliana and Larissa 15-21, 21-19, 15-12.
The Brazilians will play China's Xue Chen and Zhang Xi, who are trying to repeat their bronze medal finish from Beijing.
Walsh Jennings and May-Treanor won gold medals in Athens and Beijing without ever losing a match - in their first two Olympics, they never even lost a set - and they ran their unbeaten streak to 20 in a row with a victory Tuesday. But they gave up the first three points of the semifinal and fell behind 13-7 in the first set.
Already the most-decorated team in the brief history of Olympic beach volleyball, Walsh Jennings and May-Treanor are guaranteed at least a silver medal. No one - man or woman - had ever won two beach volleyball gold medals before they became repeat champions in Beijing, and until now, no woman had won three Olympic medals of any color.
"I had a picture in my head at the beginning of the season of how I wanted us to play, and we're living that picture," Walsh Jennings said. "But it's not over yet."
