China's Wu Collapses While Leading ATP Washington Opener
China's Wu Yibing collapsed and was helped off the court on Monday after retiring from his opening match against Japan's Yosuke Watanuki at the ATP and WTA DC Open. 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 hardcourts, 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.
