Linz (Austria), October 10: Coco Gauff reached her first WTA Tour quarter-final when Kateryna Kozlova retired in the final set of their Linz Open contest on Wednesday and could face top seed Kiki Bertens in the last eight.
Gauff, a lucky loser following Maria Sakkari's withdrawal, was leading 4-6 6-4 2-0 when her Ukrainian opponent was unable to continue due to a leg injury.
The 15-year-old American won four of the next five games from a break down at 3-2 in the second set with great fighting spirit and is set to move into the top 100 after her passage in the quarter-finals was secured.
Gauff is the youngest player to move into the last eight of a WTA event since Sesil Karatancheva back in 2005.
The teenage prodigy said: "It's been a goal of mine. In January of this year, I sent a message to my friend saying I wanted to finish Top 100, and at the time I was ranked, like, 800, so it was a far-fetched goal, but I'm glad that I was able to accomplish it.
"My other goal was to get in the main draw of two grand slams, and that happened, so I'm glad that I accomplished everything that I wanted this year."
