Serena Williams will be playing for two Wimbledon titles on Saturday after she teamed with sister Venus to reach the doubles final.

The Williams sisters struggled with their serves in the first set Friday but recovered to beat American duo of Liezel Huber and Lisa Raymond, 2-6, 6-1, 6-2. They won seven straight games to take the second set and grab a 3-0 lead in the third.

They broke Raymond's serve again in the final game, with Venus hitting a volley winner on their first match point.

Serena will play Agnieszka Radwanska in the singles final as she looks for her fifth Wimbledon title. A few hours after that, the Williams sisters are scheduled to go for their fifth title in doubles as well. They will be playing Czechs Andrea Hlavackova and Lucie Hradecka, who beat Flavia Pennetta and Francesca Schiavone of Italy in the other semifinal.

Serena said her busy schedule shouldn't affect her chances against Radwanska.

"It would be good to have a day off," she said, "but also it's good to practice in doubles because I get a lot of match play, practice some returns, some serves."

In the men's tournament, defending champions Bob and Mike Bryan were knocked out by Jonathan Marray of Britain and Frederik Nielsen of Denmark, who staved off a comeback attempt to win 6-4, 7-6 (9), 6-7 (4), 7-6 (5).

They'll play Robert Lindstedt of Sweden and Horia Tecau of Romania, who lost in the final the last two years.
