When she was just a teenager, France's Kristina Mladenovic was labeled a future star. She was one of France’s brightest hopes for a Grand Slam champion after two-time major winner Amelie Mauresmo.
At 15, Mladenovic pushed 14th-seeded Patty Schnyder to three sets at the 2009 Australian Open. She then won the junior French Open title a few months later, propelling her to the top spot in the junior rankings.
On the pro tour, Mladenovic has had plenty of success—on the doubles court. She's reached as high as No. 2, holds 16 titles, and won last year’s French Open with compatriot Caroline Garcia.
