Sunday's US Open first round pits Leylah Fernandez against Shuai Zhang on hard. Leylah Fernandez is searching for form, having lost 2 in a row (4 of the last 10). Shuai Zhang has dropped 2 straight and sits at 3-7 over the last ten.
Fernandez's 64.8% behind the first serve (against 59.7% for Zhang) means break chances should be scarce in one direction. Little separates them; Fernandez gets the nod on the finest of margins.
