Ten things you should know about Misty May-Treanor and her longtime teammate Kerri Walsh, who will be going for a third consecutive beach volleyball gold medal Wednesday in London against fellow Americans Jen Kessy and April Ross.

Reunited and it feels so good

The two split after winning their second consecutive gold medal in 2008 in Beijing. After both took time off, each returned with separate partners. In 2011, they decided to reunite for another Olympic run.

Not favored coming in

Despite being the two-time defending gold medalists, May-Treanor and Walsh were not the favorites entering the Games. They qualified for the Olympics as the third overall team, behind Brazil's Larissa Fran?a and Juliana Felisberta, who lost to Kessy and Ross, and China's Zhang Xi and Xue Chen, who May-Treanor and Walsh defeated Tuesday in the semifinals. Kessy and Ross are ranked higher than May-Treanor and Walsh on the FIVB World Tour.

Dancing With the Stars, take two

May-Treanor competed on season seven of Dancing With the Stars with Maksim Chmerkovskiy. She made it past the first two weeks but had to withdraw after she ruptured her Achilles tendon in practice. In May she began lobbying on Facebook to have fans vote for her for the show's upcoming All-Star season this fall, arguing that she hadn't been voted off and wanted to finish what she started.

Shocking Shaq Daddy

Walsh and May-Treanor appeared on the first season of Shaquille O'Neal's Shaq Vs. in 2009. The duo took on O'Neal and men's Olympic gold medalist Todd Rogers in a best-of-three beach volleyball contest. Walsh and Treanor won 11-6, 11-8.

Still undefeated

May-Treanor and Walsh haven't lost a match in Olympic competition, dating to 2004. They are 20-0 all-time. In Athens and Beijing, they didn't lose a set.

Athlete husbands

Both women are married to athletes. May-Treanor wed current Los Angeles Dodgers catcher Matt Treanor in 2004. Walsh married professional beach volleyball player Casey Jennings in 2005.

Mother to the Sundance kid

Walsh took a break after Beijing to start a family, giving birth to two boys: Joseph, 3, and Sundance, 2. Yes, the youngest is named after Butch Cassidy and the Sundance Kid. It's her husband's favorite movie.

One last time together

May-Treanor has repeatedly said the 2012 Games will be her last, in part because she wants to start a family. Walsh is expected to try to make the 2016 Olympics with a different partner.

Remembering Mom

May-Treanor's mother died of cancer in 2002. After she won gold in Athens in 2004, she spread some of her ashes on the volleyball court and did the same thing in 2008. In an interview with ABC News' Robin Roberts (http://espn.go.com/video/clip?id=8078516) she said her mother's ashes would come with her to London, too.

No uniform changes here

Despite rules changes no longer requiring beach volleyball players to wear bikinis and despite what have been some rainy and cold days on the sand in London, May-Treanor and Walsh have not ditched their bikinis.
