On Thursday, climate activists with Extinction Rebellion delayed a semifinal match by 50 minutes between Coco Gauff and Karolína Muchová. Three activists stood up in the crowd and called for an end to fossil fuels. One protester glued their bare feet to the ground. Nineteen-year-old Gauff eventually won the match, sending her to the finals. “I can’t really get upset at it,” Gauff said of the protest at a press conference afterward.
