Serena Williams vows to ease Venus's pain at Olympics

Serena Williams survived the Wimbledon Court Two trap that swallowed sister Venus and pledged to ease her pain by successfully defending their Olympic doubles gold next month.

Serena eased into the second round on Tuesday with a 6-2, 6-4 win over Barbora Zahlavova Strycova of the Czech Republic as she targets a fifth Wimbledon title, but was already looking forward to returning to the All England Club next month for the Games.

"I think it's great. I really look forward to playing doubles with her," said Serena, after she and her sister were confirmed in the US Olympic team.

"At the end of the day we're defending doubles champs, even though it's been four years. So that will be kind of cool to get out there regardless and see what happens, and more than anything, enjoy ourselves.

"I love playing doubles with her normally, but especially at the Olympics. It's a whole 'another level."

Venus's loss on Monday to Russia's Elena Vesnina was the five-time champion's worst Wimbledon defeat since 1997 when she also went out in the opening round.

Serena refused to criticise organisers for putting her out on Court Two for the second year in succession, but admitted that her sister's defeat had helped spur her on.

"I'm over it. So I don't care to talk about it," said Serena when asked about her Court Two schedule.

"I'm not here to talk about Court Two, really. I just can't talk about that right now. I'm not in the mood.

"I don't think she (Venus) felt her greatest going into that match yesterday. But I always want to play even better if she's out of the tournament."
