American Marconi Wireless News - Djokovic into Monte Carlo quarters as Medvedev rages in defeat

World number one Djokovic made a poor start and endured a second-set wobble before coming through 7-5, 6-3 against the 24th-ranked Musetti, the man who beat him at the same stage 12 months ago.

Djokovic goes on to play Alex de Minaur, the 11th seed from Australia, in the last eight.

The Serbian top seed dropped serve in the opening game against Musetti before working his way back to level at 4-4, and then snatched the set on a double fault by his opponent.

Djokovic broke twice early in the second set either side of losing his own serve to surge 4-1 ahead. Musetti clawed back to within a game but Djokovic broke again for 5-3 before closing out the win.

Djokovic has struggled to find his best form in recent times in Monte Carlo. He has not won the tournament since the last of his two titles in 2015, failing to advance beyond the quarter-finals in seven subsequent appearances.

Medvedev launched into another angry tirade against the officiating as he was beaten 6-3, 7-5 by Karen Khachanov.

Medvedev was hit with a point penalty to start the final game after berating chair umpire Carlos Bernardes and then became embroiled in a heated discussion with the tournament supervisor.

The world number four had already been warned after hurling his racquet when he double-faulted to lose his service game and leave Khachanov a game away from victory.

Medvedev, who took issue with two line calls in his second-round win on Wednesday, felt aggrieved a Khachanov forehand was not called out during a rally that resulted in the latter earning two break points at 5-5.

The arrival of the physio to treat a finger bleed at the ensuing changeover tipped Medvedev over the edge, with the Russian yelling "did I ask for the physio!" at the umpire.

- 'Open your eyes' -

He then demanded of the supervisor "who will take responsibility?" for the decisions.

Television replays appeared to show the shot in question from Khachanov had landed wide of the court.

"It's second day in a row. Guys, open your eyes. Do something. It's out," raged Medvedev.

"The mark is out. They don't know how to referee anymore. Who will take action?

"Yesterday the ball is out, it's called in. Who will take action. This ball is out there. Who will take responsibility? It's not my responsibility to referee the matches.

"It's this guy in the glasses (the line judge). He doesn't need glasses because he doesn't see anything. He should not be a referee."

Khachanov and Medvedev traded breaks in the first four games of the match before the former landed the crucial blow at 4-3 en route to taking the opening set.

The second set followed serve and Khachanov saved a set point down 5-4 before Medvedev imploded in the next game, losing both his serve and temper, and eventually the match.

Khachanov's reward is a quarter-final Friday against Stefanos Tsitsipas, who saw off fifth seed Alexander Zverev 7-5, 7-6 (7/3).

De Minaur moved into the last eight with a 6-3, 6-4 victory against fellow Australian Alexei Popyrin.

Grigor Dimitrov, last month's Miami Open runner-up, continued his good form with a 6-4, 6-3 win over Miomir Kecmanovic in a second-round match that was suspended on Wednesday because of rain.

Seventh seed Holger Rune, the 2023 finalist, shrugged off Indian qualifier Sumit Nagal 6-3, 3-6, 6-2.

World number two Jannik Sinner, who owns a 23-1 record this season, takes on Jan-Lennard Struff.
