I found one really cool set of photos of sisters Venus and Serena Williams practicing before their epic match at the US Open. The photos are chronologically ordered and each one is commented. In this post I'm showing you just some of them.

I find it especially nice that the tennis stars were both accompanied by their partners –  Venus by her fiancé, golfer Hank Kuehne, and Serena by her often-denied boyfriend, rapper Common. Read more »

Serena Williams won the 17th meeting with her sister Venus, an epic match with a final result 7-6 (8-6) 7-6 (9-7), and moved into the semifinals of the US Open where she’ll face Dinara Safina.

Serena, the fourth seed, suffered an early break of serve, but when serving for the set at 5-3 and 40-15 Venus handed the momentum to Serena. Having already seen two set points go begging in the first set, seventh-seeded Venus wasted a further eight in the second set tie-break.

Serena, who now has 9-8 record against Venus (6-5 in Grand Slams) is looking for her 12th Grand Slam final.

Serena Williams beat Severine Bremond 6-2 6-2 in the fourth round of the US Open and set up a quarterfinal clash with sister Venus. Although happy to advance, the sisters are disappointed that they need to face each other so early into the tournament.

"It sucks," said Serena.

"It sucks that it can't be the final. At least the semis. It's so soon. It's just disappointing to be so soon."

Serena and Venus Williams dominated the US Open for four years – Serena won the title in 1999 and 2002 and her older sister in 2000 and 2001. They are now the only Grand Slam champions left in the draw, plus, they haven’t dropped a set yet in the tournament. (source: Reuters, photo via news.com.au)

Venus Williams reached the quarterfinals of the US Open for the ninth time as she defeated Agnieszka Radwanska in straight sets 6-1 6-3.

The seventh-seeded Williams quickly won the first set, and staved off a mini-fightback by the Polish ninth seed in the second.

Seventh seed Venus Williams moved into the fourth round of the US Open with an imposing 6-2 6-1 victory over No.27 seed Alona Bondarenko of Ukraine.

Williams, the 2000 and 2001 champion, served three aces in the first game and never looked back. The victory came in just 56 minutes. Williams broke Bondarenko twice in both sets, while she herself faced no break points.

In the fourth round Williams will face ninth seed Agnieszka Radwanska of Poland who advanced with a 6-0 6-3 victory over Slovakia's Dominika Cibulkova.

Venus and Agnieszka have played only once so far, in 2006 in Luxembourg, when the Pole won 6-3 6-0. (photo: Getty Images)
