Clara Tauson and Sloane Stephens meet in the first round at US Open on Monday. Clara Tauson has won 4 of the last 10. Sloane Stephens is searching for form, having lost 2 in a row (3 of the last 10).

Hold strength tells the story — 67.4% versus 60.8% on first-serve points in Tauson's favor. Little separates them; Tauson gets the nod on the finest of margins.
