18:15 CET - First up, in 45 minutes, is an all-American clash between Pegula and Anisimova, and you'd have to say that the former is the favourite.
That's largely because of the H2H record, which Pegula leads 5-0, not including exhibitions. What's more, two of those wins have come in 2026, four have come on hard courts, and one has come at this very tournament, all the way back in 2020.
That being said, Anisimova was able to challenge her compatriot at the Australian Open and in Dubai earlier this year, even if she did lose, and she's played some of her best tennis in a long time this week.
17:00 CET - Good afternoon and welcome to our coverage of today's tennis at the Cincinnati Open, as the quarter-finals get underway in Ohio!
The opening match of the day is an all-American affair, as third seed and former finalist Jessica Pegula takes on world number 10 Amanda Anisimova, who has won each of her last four WTA 1000 quarter-finals.
Following that clash, men's seventh seed Flavio Cobolli faces home favourite Tommy Paul, with the American heading into the contest on the back of a three-match winning streak against top-10 players.
Later on, the headline quarter-final of the day sees Iga Swiatek continue her title defence against second seed Elena Rybakina, who is just two wins away from becoming world number one for the first time in her career.
Closing out the day, talented Frenchman Arthur Fils takes on surprise package Thiago Agustin Tirante, who has already seen off the likes of Novak Djokovic and Jakub Mensik en route to the last eight.
