America’s Misty May-Treanor and Kerri Walsh Jennings made Olympic history late yesterday when they defeated compatriots Jen Kessy and April Ross to claim their third consecutive beach volleyball title.

Watched by a crowd of 15,000 at London’s Horse Guards Parade, which included Prince Harry and David Beckham, the all-American final saw May-Treanor and Walsh Jennings prevail in straight sets, 21-16, 21-16.

“It’s insane. It doesn’t feel like it’s real,” said Walsh Jennings.

“I told Misty when we got our medals, ‘If we wake up tomorrow and have to play this match, I’m going to be furious,’ because it feels like a dream.”

May-Treanor and Walsh Jennings have never been beaten in three Olympic tournaments and dropped just one set in that time, in a 2-1 pool phase win against Austrian sisters Doris and Stefanie Schwaiger last week.

Sixth seeds Kessy and Ross had eliminated Brazilian favourites Juliana Silva and Larissa Franca in the semi-finals, but they had to make do with silver as May-Treanor, 35, brought the curtain down on her career in style.

“I think we’ve kept our emotions in check, knowing that this was going to be the last time on the sand together,” said May-Treanor.

“But it plays in the back of your mind. I have the same feeling she (Walsh Jennings) does, like you’re just floating and you’re like, ‘What’s going on?’”

It was a third consecutive 2-0 Olympic final win for May-Treanor and Walsh Jennings, who took gold for the first time in Athens in 2004 before defending their crown four years later in Beijing.

Beach volleyball was introduced to the Olympics in 1996 and May-Treanor and Walsh Jennings are the only pair to have successfully defended a women’s title.
