Meanwhile Stefanos Tsitsipas managed to pip world no 1 Daniil Medvedev to the post, making for what's sure to be a nail-biting battle of wills between the Croation and Greek players in the men's singles.
Meanwhile in the women's singles Petra Kvitova, the Czech player who has won at Wimbledon twice, beat out the USA's Madison Keys, and will now take on France's Caroline Garcia, who won against Aryna Sabalenka.
The finals, which will start at 2pm, will bring the thrilling action in Ohio to a close, after it has seen shock results including Emma Raducanu's victory over Serena Williams.
Raducanu held on beyond that match but was eventually beaten by American Jessica Pegula, with Norrie therefore becoming the Brit to last in the competition the longest.
The US Open is coming up soon and the events in Cincinnati have already given us a good flavour of what to expect at Flushing Meadows when the final major tournament of the year rolls around.
