Novak Djokovic cruised into the Western & Southern Open semi-finals, while defending champion Daniil Medvedev fell on Wednesday.

Djokovic, the world number one, continued his impressive run in New York, where the ATP 1000 event is being held instead of Cincinnati due to the coronavirus pandemic.

The Serbian may have been expecting to have Medvedev awaiting him in the last four, but the Russian exited.

Meanwhile, Stefanos Tsitsipas is also into the semi-finals.

DJOKOVIC RACES THROUGH

Djokovic needed just 62 minutes to breeze past Jan-Lennard Struff 6-3 6-1 to reach a record-equalling eighth Western & Southern Open semi.

The 17-time grand slam champion, who is yet to drop a set at the tournament, improved to 21-0 this year.

Djokovic tied Jimmy Connors, Stefan Edberg, Roger Federer and Bill Talbert's semi-final totals at the ATP 1000 tournament.

BAUTISTA AGUT BEATS MEDVEDEV

Defending champion and last year's US Open runner-up, Medvedev departed in the quarter-finals.

Medvedev, the third seed, was beaten by eighth seed Roberto Bautista Agut 1-6 6-4 6-3.

Bautista Agut has lost eight of his 11 meetings with Djokovic, but won two of their three clashes last year.

TSITSIPAS THROUGH AS RAONIC SAVES MP

Tsitsipas was only on court for 38 minutes before Reilly Opelka retired due to a right knee injury.

Opelka led 6-5 against the fourth seed before retiring due to the injury.

Tsitsipas will face Milos Raonic, who saved a match point before overcoming Filip Krajinovic 4-6 7-6 (7-2) 7-5.

Raonic saved a match point in the 10th game of the third set, winning 11 of the final 13 points to advance.
