And Radwanska takes the first set! Kerber went up an early break. She's definitely trying to be the aggressor here. I think it caught Radwanska off guard a bit. Of course, Radwanska quickly adjusted and Kerber got visibly nervous and started making a few errors. Radwanska takes it 6-3. I think Kerber was up 3-1 and lost 5 straight games, but I may be wrong.
