Tuesday, June 29, featured all of the ladies quarterfinal matches of the 2010 Wimbledon. Besides that, all other matches were doubles, mixed doubles, and juniors.

The headline of the day was when Tsvetana Pironkova of Bulgaria defeated second seed Venus Williams 6-2 6-3 on Court 1. This was the biggest upset of the tournament on the ladies draw. Venus’ shots landed everywhere but inside the court, as she had a total of 29 unforced errors, compared to Pirnokova’s 6. Pirnokova definitely had the confidence to win today’s match because she upset Venus Williams before at the first round of the 2006 Australian Open. Additionally, Pironkova became the first Bulgarian to reach the semifinals of a grand slam. Meanwhile, Serena Williams comfortably won her quarterfinal match on Centre Court against Li Na 7-5 6-3. The hope of seeing a Williams sister holding the championship trophy is still alive.

Another slight upset of the day was by #21 seed Vera Zvonareva, who defeated #8 seed Kim Clijsters 3-6 6-4 6-2. Clijsters played aggressively, as reflected by her 33 winners and 36 unforced errors. In the middle of the second set, the errors really hurt Clijsters as she let Zvonareva get back into the match. After the match, Clijsters said she was very disappointed and not too thrilled with her own level of play towards the end.

The most competitive quarterfinal match of the day was between Petra Kvitova and Kaia Kanepi. Most tennis fans are unfamiliar with these two unseeded players, who have never advanced past the second round of Wimbledon. The young Czech Kvitova won the nearly three hour battle 4-6 7-6(8) 8-6.
