Although the 35-year-old tennis star, who is expecting her first child with fiancé Alexis Ohanian, has yet to officially reveal the gender of her baby on her own, sister Venus Williams seemingly made a slip-up during her post-match interview with Eurosport after winning the second round of the French Open on Wednesday.
Venus continued that she and her two other sisters, Isha and Lyndrea Price, are all trying to get Serena to name the baby in their honor.
Serena was in the stands at the French Open Wednesday to cheer on her sister. Clay can be a grind for Williams, though, and she would do well to be wary of No. 50 Wang, who qualified in both Madrid and Rome and who has beaten France's Caroline Garcia and Russia's Elena Vesnina on clay already this spring.
As for Williams's return, in case you're wondering how sharp she will be next January, remember that she won her 23rd Grand Slam at the 2017 Australian Open, when she was pregnant. And it's not something which should be my excuse, but, you know, I got mad.
"I'm happy with the game, of course", Kvitova said, "but I mean, it wasn't really about the game today".
"I came here to win the matches", Kvitova said. Once I started I fell in love with the concept of fueling your body in the best way possible.
When asked what her duties would be as an aunt to Serena's baby, she said, "I don't know yet, that's the problem". "I don't know how well I'm going to do, because I don't know what to do".
It is the biggest first round shock at Roland Garros since Serena Williams lost to Virginie Razzano in a thrilling three-setter five years ago.
Kerber, who has battled poor form since ascending to the top of the world rankings last September, went down 6-2, 6-2 to Russia's Ekaterina Makarova in one hour and 22 minutes.
"I thought it was 4-3".
Frenchwoman Oceane Dodin won her opener against Italy's Camila Giorgi 6-2 6-3, Lesia Tsurenko of Ukraine beat compatriot Kateryna Kozlova 6-4 6-0, Aliaksandra Sasnovich of Belarus overcame Swiss Viktorija Golubic 4-6 7-5 6-3 and Latvian Jelena Ostapenko beat American Louisa Chirico 4-6 6-3 6-2.
Her staggering longevity is illustrated by the fact that her potential second round opponent is compatriot Amanda Anisimova who, at just 15, is the youngest main draw competitor since 2005.
