The quarterfinals of the women's singles of the Rogers Cup will take place in Montreal on Friday.

The last eight will feature the likes of Serena Williams, Caroline Wozniacki, Victoria Azarenka and Venus Williams.

There were several shock results in round three as no fewer than three top seeds were sent packing from the tournament. Amongst the top seeds, Maria Sharapova crashed out after being defeated by Carla Suarez Navarro of Spain.

"I couldn't find my rhythm," said the top seed, reported the Montreal Gazette.

Meanwhile, 2014 Wimbledon winner and second seed Petra Kvitova suffered a shock defeat at the hands of Ekaterina Makarova.

"I felt a little bit like being in England. It was difficult for me in my first tournament since winning Wimbledon," the newspaper quoted her as saying.

Jelena Jankovic was the other big name to exit the Rogers Cup in round three.

Serena and Wozniacki kick off the action in the quarters. It's very hard to pick a favourite here, although the Dane has been in fantastic form. It took her no more than 56 minutes to knock Shelby Rogers out on Thursday as she won 6-1, 6-0.

Serena, on the other hand, had a tough encounter against Lucie Safarova. Both players were refusing to give an inch in the first set. In the second set though, Williams was more the dominant force. In the end, she won 7-5 6-4.

"I think I served great .Yeah, I really needed to serve well today because she was just hitting unreturnable serves for me. So I was excited with my serve," said the top seed.

A battle between two top seeds is always exciting and this match promises to be no different.

Next up is Venus against Carla Suarez Navarro. Venus, who is incidentally unseeded, won a three setter against Angelique Kerber.

Navarro, meanwhile, would be cock-a-hoop after her victory over Sharapova. The Spaniard was in super form as Sharapova barely had an answer for her. In the end, Navarro won 6-2, 4-6, 6-2 and she credited her coach for the win.

"I spoke to my coach and he told me to keep it simple and I was able to do that," said Navarro.

Venus, with several Grand Slam wins to her name, and Navarro, hoping to make a mark once more, will go at each other hard.

Another closely fought encounter is on the cards as Coco Vandeweghe of America and Russia's Ekaterina Makarova go up against each other. Makarova knocked Petra Kvitova out of the tournament, while Vandeweghe knocked Jankovic out. Both appear very confident and are raring to go although the Russian is a slight favourite.

The last quarterfinal of the day shall feature Azarenka and Agnieszka Radwanska. The Pole overcame Sabine Lisicki, while Azarenka came up trumps against Heather Watson. Making an impact before the US Open is something that both ladies desire as they look to progress further in the tournament.
