Roland Garros finalist Coco Gauff will make her Top 10 debut on the Hologic WTA Tour next week. The 18-year-old American will become the youngest player to make her Top 10 debut since 17-year-old Nicole Vaidisova in 2006 when the rankings update on Monday, Sept.12.

Gauff will be the youngest American to make her Top 10 debut since Serena Williams on April 5, 1999, at 17 years, 191 days old. Gauff is currently in her third Grand Slam quarterfinal at the US Open.

US Open quarterfinal power rankings

Gauff reached a previous career-high of No.11 after Wimbledon, and she currently sits at No.12. This year, she has made the quarterfinals or better at seven events (including five of her past seven) and has compiled a 34-16 record. She currently sits at No.6 on the Race to the WTA Finals Leaderboard. 

Since turning 18 in March, Gauff has flourished. Ranked No.16 ahead of the clay season, Gauff made back-to-back Round of 16s at the WTA 1000s in Madrid and Rome before making her way into the Roland Garros final. In Paris, Gauff did not lose a set until falling to World No.1 Iga Swiatek in the championship.

Even with growing accolades, Gauff takes nothing for granted

Gauff showed no signs of slowing down after the French Open. She immediately advanced to the semifinals on the grass in Berlin and the third round at Wimbledon.

On the North American hard courts, she was a quarterfinalist in both San Jose and Toronto and was only halted by an ankle injury that forced her to retire in the first round of Cincinnati. In New York, she has yet to drop a set at the US Open in four matches.
