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.
That victory made him only the third active player to reach 20 ATP Masters 1,000 semi-finals, joining Novak Djokovic (78) and Rafael Nadal (76).
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.
On meeting Zverev for a place in the 2024 final, world number 13 Rune said: “He is one of the best players this year, so I will have to be very well prepared and physically recover and build on the level from this match.”
Bulgarian eighth seed Grigor Dimitrov plays Russian Karen Khachanov after Frenchman Ugo Humbert takes on Australian Jordan Thompson in the remaining quarter-finals later on Friday.
