Agnieszka Radwanska
Poland's Agnieszka Radwanska reached the Wimbledon quarterfinals, but there she ran into an on-form Serena Williams. And that was the end of Agnieszka's run.
Radwanska is No. 11 in the WTA rankings and has three tournament titles since the start of 2007. One of those was a win over Elena Dementieva in the finals at the Instanbul Cup.
