Mirra Andreeva has risen to a career-best No. 9 in the rankings.

(CNN) - She has capped one of the most stunning maiden years in tennis with her first WTA title, but at the age of 15, Cori "Coco" Gauff is only getting started. Gauff finished 2018 ranked just inside the world's top 700, but she soared into the top 100 at No. After Ostapenko held, Gauff played a passive service game and was broken to love. "You have a bright future, and I am really glad to share the court with you," Ostapenko told Gauff at the trophy ceremony. "It's been an unbelievable week and definitely one of the biggest accomplishments of my career so far," said Gauff.

Coco Gauff performed well at Wimbledon in 2019, and continues to advance at the 2019 U.S. Open. (CNN) - A tournament that began in defeat for Coco Gauff ended with the popular teen claiming her first tennis title. Gauff lost in the qualifying rounds but still made the tournament's main draw after another player pulled out with an injury. Back then Gauff went through qualifying rounds before upsetting one of her idols, Venus Williams. Just like in New York and London, the fans took to Gauff in Linz, and she acknowledged them afterward.
