Of course, Jelena Jankovic does not like to play against tennis players such as Agnieszka Radwanska. She does not like when her opponents play below her speed. I think it will be difficult for the Serbian. In my opinion, Radwanska is in good shape, she showed some good tennis in the match against Dominika Cibulkova. There was a struggle, but the Pole managed to win, looking decent.
Judging from the first matches, Jankovic is in good condition, too. She beat Vandeweghe very easily, letting the opponent win just one game. But Radwanska won’t give out so many gifts to Jankovic, of course. There will be a lot of long games. Actually, I always liked Jankovic. But she rarely plays well now. She played against Radwanska at this tournament in 2014 and Agnieszka won in three sets. I’m almost sure the Polish player will win again, possibly in two sets. But there will be fight in them. That’s why I assume the match will see over 20.5 games.
