Top seed Victoria Azarenka scored her most impressive win over Agnieszka Radwanska in 12 career meetings, dismantling the fifth-ranked Pole 6-0, 6-2 in the BNP Paribas Open quarter-finals Wednesday.

"I just had very good motivation because I knew she's a very good player," said the 22 year old, who improved to a 9-3 record against Radwanska. "I have to play a very good match and show excellent tennis to beat her, so that's what I was mainly focus on. I hope I was a good example of woman's tennis.

"I think I was executing my shots brilliantly, and I was going for whatever was coming at me, so I really had a clear mind and clear game plan of what I had to do."

Radwanska narrowly avoided the double bagel, breaking Azarenka at 5-0 in the second set, but the Belarusian clinched the 68-minute victory at the second time of asking to match Serena Williams’s 21-0 start in 2003. Four of her wins this season have come against Radwanska.

"My strategy is always try to be better every day," said Azarenka, the only player on the WTA tour to win mulitple titles in 2012. "It doesn't matter how good it's gonna be. It's just to try to be better and give everything you can on that particular day. Doesn't matter if it's practice, match, fitness, whatever it is. That kind of gives me mental advantage for myself to be to know that no matter what, I did my best and I tried my best. I'm just trying to enjoy every moment I play and trying to be better every day."

Azarenka moves through to the semi-finals for the second time in Indian Wells, and will face No. 18 seed Angelique Kerber. Kerber secured her first win in four meetings with Na Li, defeating the reigning French Open champion 6-4, 6-2. Kerber capitalized on five of her nine break point opportunities to seal the victory in 84 minutes.

"I felt very good out there and I started very well, but she was also playing tough," said Kerber. "I just tried to move very good and hit the balls deep in the court and also play aggressive tennis, focusing on me. I'm happy that I'm in the semis now."

The German will contest her fourth semi-final of the season, and seventh overall in her last 12 tournament appearances. Kerber captured her first WTA title at the Paris Indoors event, notching her first Top 10 wins against Maria Sharapova and Marion Bartoli en route to lifting the trophy.
