Team USA's beach volleyball star Kerri Walsh Jennings kicked off her 38th birthday with a midnight win over Australia and a serenade Sunday night.
After Jennings and April Ross advanced to the Rio Olympics beach volleyball semifinals, defeating Louise Bawden and Taliqua Clancy 21-14, 21-16, fans at the Copacabana beach volleyball venue — which included NBA stars Kevin Durant, Draymond Green, DeAndre Jordan and Jimmy Butler — sang "Happy Birthday" to the three-time gold medalist.
"I’ve had other birthdays during the Olympics, but I don’t think I’ve been serenaded before,” Walsh Jennings said after the match. “So that was a unique experience, and I loved it."
The U.S. basketball players were in the arena to cheer for their fellow Americans. They tried to get a wave going and started a "U-S-A!" chant when they were shown on the venue video board. They also squabbled with fans behind them — it's hard to see past a 6-foot-11 NBA forward — but engaged in some playful banter with Australia fans across the sand.
Ross said she has enjoyed the way athletes from different sports meet and root for each other.
"That's one of the biggest things I love about the Olympics," she said.
The Americans will play Brazil's Agatha and Barbara — the defending world champions — on Tuesday, with the winner advancing to the gold medal match. The other women's semifinal match will feature Germany and the top-seeded Brazilian team of Larissa and Talita.
