Figure skating:

As he has done since his last loss at the Pyeonchang Olympics, Nathan Chen was nearly perfect and rather playful in winning the short program Saturday at the U.S. Figure Skating Championships. Seeking a fifth straight national title, something no man has done since Dick Button from 1946-52 with seven, Chen put out the most difficult routine that any man anywhere attempts. He hit a quadruple lutz, triple axel and an excellent quad flip-triple toe loop combination in scoring 113.92 points.
