The mighty Williams sisters, Venus and Serena, secured a berth in their fifth Wimbledon women's doubles final on Friday.

The unseeded siblings came from behind to upend the top-seeded team of fellow Americans Liezel Huber and Lisa Raymond, 2-6, 6-1, 6-2, at the All England Club. The 35-year-old Huber is a five-time major doubles titlist, while the 38-year-old Raymond owns six such titles. They are the reigning U.S. Open champs.

The Williams' opponent in the final will be a sixth-seeded Czech tandem of Andrea Hlavackova and Lucie Hradecka, who overcame unseeded Italians Flavia Pennetta and Francesca Schiavone, 2-6, 6-3, 6-4. Schiavone is a former French Open singles champ.

The 25-year-old Hlavackova and 27-year-old Hradecka were last year's French Open doubles champs.

The 32-year-old Venus and 30-year-old Serena already own 12 Grand Slam doubles titles, including Wimbledon ones in 2000, 2002, 2008 and 2009. They haven't paired for a major doubles title since 2010, when they captured Australian and French Open titles.

The sisters are also two-time Olympic gold medallists in doubles and will play for some more doubles gold here at the All England Club in a few weeks as the tennis for the London Olympic Games will be staged on these hallowed lawns.

Serena will play for a fifth Wimbledon singles championship here on Saturday.

Saturday's winning doubles team will split $400,000.
