Coco Gauff and Cristina Bucsa meet in the round of 32 at US Open on Saturday. Coco Gauff is rolling — 7 straight wins, 9 of 10 in recent play. Cristina Bucsa has won 3 of the last 10.

Gauff's 65.8% behind the first serve (against 58.8% for Bucsa) means break chances should be scarce in one direction. Anything other than a Gauff win would rank among the bigger surprises of the week.
