Predicted Winners in BOLD
[5] Caroline Wozniacki (DEN) vs Julia Goerges (GER) – An upset would surprise but not shock me in this match.
Danka Kovinic (MNE) vs. Kristina Mladenovic (FRA) – Home court edge
[4] Petra Kvitova (CZE) vs. Silvia Soler-Espinosa (ESP) – If Petra can play close to her best level, she is a huge factor in deciding this tournament.
[1] Serena Williams (USA) vs. Anna-Lena Friedsam (GER) – Serena has to be more careful on clay with a match like this, but she should win.
[18] Svetlana Kuznetsova (RUS) vs Francesca Schiavone (ITA) – Two former champions duel.
[27] Victoria Azarenka (BLR) vs Lucie Hradecka (CZE) – Vika’s athleticism should help her on clay, but to this point in her career clay has not been her friend.
[12] Karolina Pliskova (CZE) vs. Andreea Mitu (ROU)
[32] Zarina Diyas (KAZ) vs. Alison Van Uytvanck (BEL)
[17] Sara Errani (ITA) vs Carina Witthoeft (GER) – Errani has had a lot of good moments in Paris.
Sesil Karatantcheva (BUL) vs. Irina Falconi (USA) – This has not been a great event for US citizens.
[30] Irina-Camelia Begu (ROU) vs Ana Konjuh (CRO) –
[10] Andrea Petkovic (GER) vs. Lourdes Dominguez Lino (ESP)
[23] Timea Bacsinszky (SUI) vs. Tereza Smitkova (CZE) – Swiss power?
[16] Madison Keys (USA) vs Belinda Bencic (SUI) – See above
Heather Watson (GBR) vs. Sloane Stephens (USA) – This should be a lot of fun, but Stephens backhand down the line can be a great weapon especially on a surface that makes footing difficult.
Tsvetana Pironkova (BUL) vs. Denisa Allertova (CZE)

I was shocked, too, to see Wozniacki lose today.
By the way, I love the blog!
Thanks Chad! Some of these upsets were crazy.
