Kasatkina celebrates 21st birthday with special cake
It's time to pop the bubbly—Daria Kasatkina has turned 21.
The crafty Russian has enjoyed a strong 2018 so far with runs to the final in both Dubai and Indian Wells, so she deserves a hearty celebration.
Kasatkina celebrated the milestone birthday with a tennis-themed cake in Madrid, where she's into the round of 16 after wins over Wang Qiang and Sorana Cirstea.
The world No. 15 had a slow start in Madrid, but found her game in her second match against Cirstea.
Kasatkina will aim to bring her best against Garbine Muguruza on Wednesday.
