Coco Gauff took a tumble from the top on Monday, losing in the opening round of Wimbledon to Sofia Kenin. 

Kenin won 6-4, 4-6, 6-2 on the first day of the tournament, serving Gauff her first ever opening-round defeat at Wimbledon in the upset victory.

The 24-year-old struggled to find words after the highlight-filled win.

“I’m just super,” Kenin began her on-court interview before catching herself. “Oh, my God. I can’t even, like, talk. I’m super happy. Coco played a tough match. I knew I needed to play my best in order to win.”

Gauff, 19, entered the tournament ranked No. 7 in the world while fellow American Kenin, 24, was seeded 128th after three straight first-round defeats at major tournaments.

Kenin, the 2020 Australian Open champion, improved to 4-0 in the first-round at Wimbledon after falling to Gauff earlier this year at the Auckland Open.

Gauff beat Kenin 6-4, 6-4 in Auckland enroute to earning the title when she took down Rebeka Masarova in straight sets in the final. 

Kenin has yet to make it to the third round of Wimbledon and will battle China’s Wang Xinyu on Wednesday for a spot. 

The time of Wednesday’s second-round match has yet to be determined.
