Wimbledon 2012: Serena vs Kvitova Live Online Stream

When the quarterfinals of the women's singles at 2012 Wimbledon starts for the day, all eyes will be focused on the most promising encounter - the Serena Williams vs Petra Kvitova encounter at Centre Court. It is the second match in the main show court and features the last two winners at Wimbledon. The 6th-seeded Serena is the champion in 2009 and 2010, and in two other earlier occasions. Kvitova won her first major last year defeating Maria Sharapova in the final. Watch Serena vs Kvitova in Wimbledon 2012 women's singles quarterfinal live online here.

Serena and Kvitova are two of the three remaining Grand Slam champions left in the draw. The other major champion is this year's Australian Open champ, world no. 2 Victoria Azarenka who will be going against the only unseeded player left in Austria's Tamira Paszek. Azarenka and the world no. 3, Poland's Agnieszka Radwanska, are in the running for the world no. 1 ranking after top-ranked Maria Sharapova lost a straight set shocker to German Sabine Lisicki. Azarenka is in Serena and Kvitova's half of the draw which means that there will be a first time Grand Slam finalist, and a 50% chance of having a first time Grand Slam winner, in this year's Wimbledon.

The day's most important - and fascinating - contest will be that between Williams and Kvitova and the sadness is that one will depart the scene. It is a tough one to call. Serena, four times a champion and twice the runner-up at Wimbledon, has the experience, the background and, at 30, definitely the incentive to hoist the Venus Rosewater Dish one more time, while Kvitova, the hard-hitting left-hander from the quiet Czech town of Fulnek, will understandably want to repeat last year's performance.

Serena has the edge when it comes to previous clashes, having won both. She conceded just three games to Kvitova in the second round of the 2010 Australian Open and then pulled off a much closer victory 7-6, 6-2 in the 2010 Wimbledon semi-finals. But as the sport's Serena-watchers have observed since she fought back from a serious illness and injury lay-off, a degree of uncertainty has crept into that once iron-clad game of hers. Will the errors outweigh the winners? Will the Kvitova howitzer forehand be too much? A great match is in prospect.

Serena Williams' passage to the quarterfinals has certainly not been plain sailing, and with defending champion Petra Kvitova standing in her way next, the journey is unlikely to get any smoother. In her third and fourth round matches, against Zheng Jie and Yaroslava Shvedova, Williams had to summon upon all her reserves of physical and mental energy, scraping by both in three grueling sets.

Kvitova had a scare of her own on Monday; coming from a set and a break down to defeat an inspired Francesca Schiavone. This was in stark contrast to the first three rounds, in which the Czech had barely broken sweat and looked to be approaching the devastating form that took her to last year's title. As one of the few players on tour capable of trading on equal terms with Williams, an on-form Kvitova will believe the match is on her racquet. What makes the encounter all the more intriguing is that Williams is undoubtedly thinking the exact same thing.

The winner for sure will be tennis fans who are excited about this match-up. But, who will show up for the day? Will it be the Serena who won thirteen Grand Slams, or the Kvitova who played fearless tennis in her first major final last year?
