While she credited Agnieszka Radwanska with playing amazing tennis in the Pole’s three-set upset of her in the Australian Open quarterfinals, two-time defending champion Victoria Azarenka said she more or less had a brain freeze.

“[I need to] think a little bit more on the court,” she said. “Just try to figure out during play, not just kind of be in the clouds and watch the opponent play amazing. Just have to do something, something different, even if it's something that I don't like to do.”
