Teenager Coco Gauff was knocked out of the Luxembourg Open in the first round - just days after winning her maiden WTA title.

American world number 71 Gauff, 15, was beaten 6-4 6-0 by Russian eighth seed Anna Blinkova in just 59 minutes.

Gauff became the youngest player to win a WTA title in 15 years in beating former French Open champion Jelena Ostapenko in the Linz Open final.

Gauff and compatriot Caty McNally are in the women's doubles quarter-finals.

"I'm very happy with my performance," said world number 66 Blinkova, who will play Germany's Tatjana Maria in the second round.

"I didn't make a lot of mistakes and I had the right tactics. I was calm and I did my job well today.

"I was very focused. I know she's a great player and I knew she was coming off a WTA tournament win, so I was well prepared."
