PARIS -- Russian teenager Mirra Andreeva was already a tennis phenom at age 15.
At 19, she's a Grand Slam champion.
The eighth-ranked Andreeva ended the run of 114th-ranked Polish qualifier Maja Chwalinska with a 6-3, 6-2 victory in the French Open final Saturday.
Andreeva became the youngest player to win the women's singles title since Monica Seles, who was 18 when she landed her third straight French Open in 1992.
