Novak Djokovic reached his sixth Paris Masters final with a 7-6 (5), 6-4 win Saturday against Grigor Dimitrov, beating him for the ninth time in their 10 career matches.
The top-ranked Serb remains on course for a fifth title at Bercy Arena and a 55th career showdown against old rival Rafael Nadal. The second-ranked Spaniard was playing his semifinal later Saturday against hard-hitting Canadian Denis Shapovalov.
Djokovic and Dimitrov won more than 80% of first serve points in a tight opening set where neither faced a break point.
But when it mattered, Dimitrov cracked in the tiebreaker.
With Dimitrov 5-4 up and controlling the exchanges, a 32-stroke rally ended when he advanced to the net and tried an extravagant forehand volley to the left. He could have played an easier shot with a controlled backhand to the vacant right side of the court.
The ball landed out and Djokovic punched the air, roaring in relief.
Then, on set point, a 35-stroke rally ended when Dimitrov chopped a backhand long.
Djokovic broke him in the fifth game of the second set, the unseeded Bulgarian mis-hitting a forehand and sending it long.
Serving for the match, Djokovic held to love and clinched victory when Dimitrov sent a return wide at full stretch.
Djokovic won his first title here 10 years ago and then three straight from 2013-15. He lost his only final, last year, to Karen Khachanov.
Djokovic is bidding to finish the year as No. 1 for the sixth time.
