Marketa Vondrousova upsets world number four Jessica Pegula at Wimbledon

The American looked poised to progress to the maiden grand slam singles semi-final of her career having overturned a one-set deficit to lead 3-1 in the decider.

But, due to forecasted rain, the contest was halted for around 23 minutes to allow the roof on Court One to be closed and 2019 French Open finalist Vondrousova returned to win five of the next six games to progress 6-4 2-6 6-4.

The Czech world number 42, who is enjoying her best run at the All England Club, will take on either world number one Iga Swiatek or Elina Svitolina for a place in the final.

"I don't know what happened," she said. "It's an amazing feeling, I cannot believe it."

Asked how much closing the roof helped her, she replied: "A lot actually. I never played on court number one under the roof. It's amazing.

"I just wanted to stay as long as I could and I fought until the end. She was pushing me to the edge so I am just so proud of my game."
