A spot in the next round is at stake on Thursday, when Katie Boulter goes up against Katie Volynets in the Cincinnati first round. Katie Boulter is searching for form, having lost 5 in a row (4 of the last 10). Katie Volynets is 6-4 across recent matches.
Boulter's 67.6% behind the first serve (against 56.9% for Volynets) means break chances should be scarce in one direction. A tiebreak or two would surprise nobody, with Boulter fractionally more likely to land the big points.
