Alexander Zverev will face Holger Rune in the semi-finals of the Paris Masters after beating Stefanos Tsitsipas in straight sets.
German world number three Zverev defeated Greek 10th seed Tsitsipas 7-5 6-4 on Friday.

Semi-final opponent Rune overcame Australian ninth seed Alex de Minaur 6-4 4-6 7-5.
Zverev, 27, is chasing his seventh career Masters 1,000 title and second of the season following his triumph in Rome.
He next faces a former Paris champion in Danish 21-year-old Rune, who won the tournament in 2022 by beating Djokovic in the final.
