There's a lot going on in the third round of Wimbledon, in terms of who plays whom.
They meet again: Carla Suarez Navarro defeated defending champion Venus Williams in the second round of the Australian Open, and now they meet again in the third round of Wimbledon. That was a hard court and this is grass, which--for Venus Williams--changes the dynamics dramatically.
Excuse me, you're on the wrong side of the net: Daniela Hantuchova has to play her doubles partner, Ai Sugiyama, in the third round. Probably not fun for either of them.
How many Russians does it take to change an outcome? There are seven in the 3rd round, and two of them--Regina Kulikova and Elena Dementieva--play each other.
I didn't catch your name: Four of the third round pairings feature players who are playing each other for the first time: Dinara Safina vs. Kirsten Flipkens, Sabine Lisicki vs. Svetlana Kuznetsova, Melanie Oudin vs. Jelena Jankovic, Roberta Vinci vs. Serena Williams.
