China’s Wu Yibing collapses while leading ATP Washington opener, has to retire at 4-1 up in first set
- Wu wobbles before falling over back of chair as he tries to take a seat during first set against Japan’s Yosuke Watanuki

China’s Wu Yibing sparked concerns over his health after collapsing on Monday during his opening match against Japan’s Yosuke Watanuki at the ATP and WTA DC Open.
Wu had to be helped from court and eventually retired through injury just five games into the match.
It was the second notable health incident in a match within a month for Wu, who needed a medical timeout after falling ill at the end of the first set in his opening-match Wimbledon loss to American Frances Tiafoe.
On the Washington hard courts, Wu was leading 4-1 in the first set when he made a wobbly step, went to take a seat and collapsed forward over the back of a folding chair.
Wu was helped to his feet and eased down onto the court with an umbrella quickly brought over to provide shade. He was later helped to walk off the court.
