Coco Gauff was left in tears after she became the biggest Wimbledon casualty so far on Tuesday night - crashing out to World No 42 Dayana Yastremska.

The American, who rocked up in London having just claimed the French Open title, was looking to continue her good form but struggled on Day Two as she was well beaten 7-6, 6-1 by her Ukrainian opponent. Gauff's match was scheduled to be played on Centre Court, but was moved late in the day.

Matches on Centre Court dragged on and it meant Gauff could be switched to Court One to play earlier. The switch wasn't part of the script but Gauff, who first made her name at Wimbledon as a teenager, refused to blame the logistics for her loss.

She had been prepping for a late night as she was due to follow Novak Djokovic, but despite being overcome by emotion the American insisted the court switch had no influence on the result.

The World No 2 said: "Obviously, I was preparing to play a little bit later. I found out at about 6:35pm that we would not be on before 7:30pm. At that point I hadn't really eaten yet. I was trying to hold off because I thought maybe we were going on after Novak [Djokovic on Centre Court].

"I don't think it really affected the match today, to be honest. I've played with quick turnarounds and things like that. Yeah, I figured we would be moved at some point, but we don't know. But I definitely don't think the court change affected the way the match went."

Gauff made a number of errors with her double fault count particularly high and she admitted that she will take a different approach next time she comes to Wimbledon. "I just feel like the surface, I maybe could have used more matches," she said.

"If you go deep in Roland Garros, you're debating: 'do I rush and play that week, or do I take time and play the week before?' It's a tricky thing. It's like finding the puzzle. I don't like to play the week before. It's a quick turnaround, so I think just trying to learn whether it's better to train more and maybe play Bad Homburg or Eastbourne. If that time comes around again I'll approach it differently."

Gauff also admitted: "I have faith that if I can make these adjustments, I can do well here. I really do want to do well here. I'm not someone who wants to write myself off grass this early in my career, but I definitely need to make changes if I want to be successful here."

The women's draw has seen several top ten players fall before the second round. Earlier on Tuesday Gauff's fellow American and third seed Jessica Pegula was beaten. China's Zheng Qinwen was also a major casualty.
