Novak Djokovic thrashed Taylor Fritz while Carlos Alcaraz fought back from a set down as the top-ranked pair reached the semi-finals of the Cincinnati Open.
Djokovic took just 61 minutes to beat American Fritz 6-0 6-4 and will play Alexander Zverev next.
World number one Alcaraz won 4-6 6-3 6-4 against Max Purcell to set up a semi-final tie with Poland's Hubert Hurkacz.
The pair are on course to meet for a rematch of last month's Wimbledon final, which Alcaraz won.
Second seed Djokovic is playing in his first tournament on American soil since 2021 after missing last year's US Open and other tournaments because of his Covid vaccination status.
