Over the weekend the defending champion Czech Republic moved into the final behind current Wimbledon holder Petra Kvitova, and in the final they will meet the hungry Serbian squad, powered by former No. 1s Ana Ivanovic and Jelena Jankovic, with the Serbs in their first-ever final.

Serbia will front two former No. 1s in Ana Ivanovic and Jelena Jankovic, while Russia counters with former world No. 2 Svetlana Kuznetsova, and Anastasia Pavlyuchenkova appearing in her fifth tie.

“I didn’t expect to play that well,” Dimitrov said. “I didn’t make enough first serves, though. Got a bit lucky at 4-4 in the third, and I was happy to close the match.”

Novak Djokovic is into one semifinal, will Roger Federer and Rafael Nadal clash in the other?

“I was pissed, yeah, in the first set especially losing 6-love is not fun,” Radwanska said. “Especially when you expect that you’re at this kind of level that you can beat anyone. But then I was seeing that she was playing just too good.”

Roger Federer blunted the power of big serving Milos Raonic to advance to today’s fourth round.
