SWilliams is ready for Wimbledon again at Olympics

Serena Williams says she feels "really good" and is ready to go for another title at Wimbledon.

But whether it's for three Olympic golds or just two is still up in the air.

Williams pulled out of a World Team Tennis match in Washington last week to rest her back before the Olympics. She said Tuesday she doesn't have any injury concerns as she prepares for a quick return to the All England Club. She won her fifth Wimbledon title there this month and also teamed with sister Venus to win the doubles tournament.

Serena said at a news conference with the U.S. team that "I feel really good going into these Olympic Games, and wanting to do really well."

The Williams sisters will be defending their gold medal in doubles, but team officials say they won't pick players for mixed doubles until next week.
