With her own kind of perpetual motion, Danielle Collins transitioned swiftly from an Australian Open loss to the world's top-ranked player to announcing this would be her last season on the professional tennis tour. While Iga Swiatek was still doing an post-match, on-court TV interview, the 30-year-old American entered a small interview room. The 2022 Australian Open runner-up had just lost five straight games to surrender a 4-1 third-set lead against Swiatek, eventually going down 6-4, 3-6, 6-4 in a 3-hour, 14-minute match on Rod Laver Arena.
