Milos Raonic scored his best ranking win beating Andy Murray in the Barcelona semifinals.

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.

“I lost against her the last few times, but today was a very tight match too, and I think I was better for just a couple of points each set,” Radwanska said. “Maria is a really good player — a top player, second in the world right now. So I had pretty much nothing to lose. I was focusing on my serve, and I’m very happy I didn’t lose my serve — I think it was actually the biggest key in this match.”

Wildcard Venus Williams also saw her run come to an end at her first event of 2012, worked over by No. 5 seed Aggie Radwanska 6-4, 6-1, who will next face Bartoli.

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

“It doesn’t feel like it’s too far out of my grasp,” Raonic said. “It’s like somebody dangling a piece of cake in front of my face and then taking it away at the last second. I’ll definitely be back.”
