World No. 1 Novak Djokovic claimed his 50th match win of the season Thursday in Montreal as he reached the Coupe Rogers quarter-finals with a 6-2, 6-1 victory over Jack Sock.
The Serbian, who has lost just three matches this season, dispatched the No. 35-ranked Sock in 54 minutes to set a quarter-final clash with either Ernests Gulbis or Donald Young.
In his first meeting with the 22-year-old Sock, Djokovic was ruthless, relinquishing just 10 points on serve and breaking the American four times from six opportunities. Sock was bidding to reach his first ATP World Tour Masters 1000 quarter-final.
“I never played him before so it took me some time to really figure out what his patterns were of the serves, his game in general,” Djokovic said of Sock. “I did watch him many times before, but it’s different when you’re standing on the court trying to read the rotation, especially of his forehand because he’s got a very quick wrist, very quick motion, good forehand.
“I think turning point was the 3‑2 game when I made a break. After that I just felt in control of the match.”
