Her convincing 6-2, 6-4 victory left her stunned.

Tennis Channel announcer Ted Robinson proclaimed, A star is born, according to the Post. The tournaments Twitter account dubbed her Teen Queen.

Anisimova is ranked 51st in the world and Halep is No. 3 . So, yep, thats an upset. Yet Anisimova has yet to lose a set in Paris, Tennis.com reported.

She was born in New Jersey and moved to Miami at age 3, according to her WTA bio . Her dad Konstantin, who emigrated from Russia in 1998, has been her coach.
