Same name, same game? Not if you're Daria Gavrilova and Daria Kasatkina, two of the most impressive young risers of the 2016 season.
Each have earned career-high rankings this year despite a fire and ice on-court contrast. Gavrilova's boundless energy and big cuts at the ball have earned her wins over Petra Kvitova and Simona Halep. Kasatkina's steadier rise and smoother swings helped her begin the season by beating Venus Williams and Timea Bacsinszky.
Off the court, the pair are completely in-sync, finishing each others sentences and joking about everything from their first meeting on the singles court at last year's US Open to their decision to play doubles this summer.
