Italy's world number two Jannik Sinner beat Holger Rune 6-4 6-7(6) 6-3 in the quarter-finals of the Monte Carlo Masters on Friday after his Danish opponent saved two match points.
Rune beat Sinner in the semi-finals last year but this time it was the second seed who prevailed as he reached a fifth semi-final in as many tournaments this year.
Rune had played two matches on Thursday, first finishing his rain-affected clash with Sumit Nagal before a 3-1/2 hour thriller with Grigor Dimitrov where he saved two match points, with both games going the distance.
He looked far from fatigued as faced the Australian Open champion in bright sunshine but the 20-year-old also took on the crowd, who jeered and whistled at him while he also argued with the chair umpire over a line call.
Sinner took the first set and looked destined to seal a straight-sets victory at 6-4 in the second set tiebreak, but Rune saved two match points once again -- one with a superb cross-court forehand winner -- before levelling the tie.
The final set went with serve until 4-3 when Sinner converted the decisive break point after Rune made a costly double-fault and the Italian held his nerve to serve out the contest.
In the day's opening quarter-final, 12th seed Stefanos Tsitsipas beat Karen Khachanov 6-4 6-2 in a rematch of last year's Australian Open semi-final as the Greek looks to return to form after a mixed record in 2024.
Tsitsipas arrived at the tournament with a 11-6 win-loss record this year but has fond memories of the Monte Carlo Masters where he won the title in 2021 and 2022.
Bolstered by a strong first serve, Tsitsipas put Khachanov to the sword by converting four break points to end his run and improve his head-to-head record against the Russian to 8-1.
