NEW YORK: Coco Gauff and Karolina Muchova were all over the court in that 40-ball rally, the longest exchange of their US Open semifinal. The penultimate point of the match. The American gave it spin and the Czech responded with slices. There was stellar use of power and poise, real estate and electric sprints. The crowd gasped and the women in the middle breathed heavily. Gauff finally stepped in and knocked off a forehand winner that gave her a sixth and final match point.
