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 by 6-3, 6-2 in the French Open final on 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.“You’re so young and talented. It’s so annoying,” Chwalinska told Andreeva during the awards ceremony.Chwalinska was attempting to become the first qualifier to capture the Roland Garros title.When Andreeva executed a backhand cross-court winner on her first match point, she released her racket and dropped down onto the clay on her knees to celebrate as she covered her face with her hands.During the trophy presentation, Andreeva took the unusual step of thanking herself “for believing in myself, always giving my 100%, even when it’s tough, trying every day to be better as a person and as a player, believing that I can do this, fighting so many demons inside of me.“Only I know how tough it was for me,” Andreeva added. “How nervous I was throughout these two weeks.”Andreeva also thanked her psychologist, who she said was watching from Florida: “Everything that you’ve told me I’ve been trying to use these two weeks and I would say that it worked not bad. So thank you so much.”Andreeva was born Siberia and moved to Sochi and eventually France to develop her tennis career.She drew a loud applause from the crowd on Court Philippe-Chatrier when she spoke a few words of French during the trophy presentation.“Thanks for your support today and over these past two marvelous weeks here in Paris,” Andreeva said. “It was very important for me.”Alexander Zverev plays Flavio Cobolli in the men’s final on …
