Flavio Cobolli vs Arthur Fils — SF — Cincinnati Open

Three winners against 22 is what the seventh seed came up with, and the ranking sheet was the only thing calling this an upset: the betting market had installed Fils as a 70 percent favorite. Cobolli was broken three times in the opener and won 7 of his 35 first-serve return points. The first set went on consecutive breaks, the last of them in game 9 for 6-3, and a single break in game 1 settled the rest. Fils had taken both prior meetings on record, both on clay; this first hard-court edition ran 67 minutes and sends him to the Cincinnati final with a shot at the title.
