One showed up to play--the other showed up. Angelique Kerber looked as good as she has ever looked today. She undoubtedly knew that Agnieszka Radwanska was ripe for the picking, but why can't Kerber bring this kind of confidence to her matches, anyway? She's capable of more than defense, and considering how good her defense it, that makes her pretty capable.
At any rate, the German star is now 1-1 in Istanbul, so she stays in the mix. She never even saw a break point today, but she broke Radwanska four times, and defeated her 6-2, 6-2. Here she is giving Aga a bit of her own "Radwanska":
Serena Williams is now 3-0 and gets a day off tomorrow. Williams defeated Petra Kvitova in straight sets, and without having to work too hard. The world number 1 was just too good.
Finally, in the only three-setter played so far at the Championships, Li Na defeated Jelena Jankovic 6-3, 2-6, 6-3.
Tomorrow, Li takes on Victoria Azarenka, who appears to be carrying as much fatigue as Radwanska, but that doesn't make it a walk in the park for Li, who can "go off" at a moment's notice (and Azarenka can "switch on" at a moment's notice, too). Jankovic will play Errani, who is currently 0-2 at the event, which makes her a bit dangerous. Kerber will play Kvitova. I'll miss all of it, but will try to catch some of the replays.
