Arthur Fils vs Frances Tiafoe — F — Cincinnati Open

Fifteen unforced errors in the second set, with Tiafoe breaking for 2-0, then 5-1, then 6-1, had the trophy drifting away from Arthur Fils. The reset came at once: a break in game 2 of the decider for 2-0, another in game 4 for 4-0, 11 aces against a single double fault for the match while the American put three doubles into that closing set alone. It is Fils's first title at Masters level, where semifinals at Miami and Madrid had been his ceiling this season. Tiafoe saved two match points; the Cincinnati Open final still took only 1 hour 28 minutes.
