The fourth-ranked Radwanska made quick work of the former No. 1 from Serbia in the first set, breaking her four times amid windy conditions. Ivanovic didn't help her own cause, committing 21 unforced errors and only getting 63 percent of her first serves in.
The second set was closer, with both players holding serve until Ivanovic broke with a forehand winner to go up 6-5 only to see the Pole break back to force the tiebreak.
Ivanovic was 2-0 in the tiebreak but couldn't hold her momentum. Radwanska put it away with a lob that Ivanovic hit into the net.
