Djokovic sees off Karatsev to ease into last 16 in Rome

Novak Djokovic's love affair with Rome continued as the five-time champion picked up his 60th victory at the Italian Open with a 6-3, 6-2 success over Aslan Karatsev on Tuesday.

The Serb has never lost before the quarter-finals at the tournament and is now just three victories shy of joining the 1,000 match-wins club.

"He probably has the biggest calf we have in tennis. Very strong guy, just solid from the baseline," Djokovic said of the 35th-ranked Karatsev.

"You never know with him. If he's feeling the ball, he can be very dangerous because he stays so close to the line, puts pressure on his opponents."

Karatsev committed 36 unforced errors during the match and Djokovic made sure to capitalise on those mistakes.

"He was missing a lot of points today though, gave me a couple of breaks there in the first and second.

"I'll take this win for sure. It's a straight-sets win against a quality opponent and I'm looking forward to the next challenge," continued the Serb.

Djokovic, who is in his record-extending 369th week as the world number one, must reach at least the semi-finals in Rome to hold onto his top ranking, and avoid being overtaken by Daniil Medvedev.

In the last 16, Djokovic will face compatriot Laslo Djere or three-time major champion Stan Wawrinka.

Djokovic started with a break of serve en route to a 2-0 lead but Karatsev erased his deficit in no time to draw level.

The top seed upped the pressure to break again in the eighth game and closed out the set in style, showing off his volleying skills in front of a buoyant Rome crowd.

Djokovic raced to a 4-0 advantage in the second set and sealed the 90-minute victory on his first opportunity, to improve to 2-1 in his head-to-head against Karatsev.
