20:00 CET - Good evening and welcome back to our Tennis Tracker ahead of both finals in Cincinnati.
First up, at 22:30 CET, is Arthur Fils against Frances Tiafoe.
Both have won four ATP titles in the past, but this would be the biggest of their careers. The American, Tiafoe, has been here before on this court, where he lost to Jannik Sinner in straight sets two years ago.
It is new ground for the Frenchman, who has never played in a Masters final.
They have met just once before, making this an intriguing spectacle, with Fils beating Tiafoe in Miami last year over three sets.
Later on in the WTA 1000 event, it's an all-American affair where Jessica Pegula faces Coco Gauff.
We are expecting tension in this one, with no clear favourite and one that could go the distance.
Pegula leads the head-to-head 5-4, including going 4-1 on hard courts.
For what it is worth, Gauff won their latest encounter in the quarter-finals of Wimbledon a few months ago, but only after rallying from a set down.
