Mirra Andreeva, 19, claims her first Grand Slam title at the French Open, defeating Maja Chwalinska in straight sets.

On triple match point, she broke with a backhand winner and then fell to the court on her knees.

Russian teenager Mirra Andreeva was already a tennis phenom at age 15. At 19 she’s the French Open champion.

The 19-year-old Andreeva, who defeated Poland’s Maja Chwalińska, will take home $3.2 million in prize money for her feat.
