Serbian Novak Djokovic secured his place in the third round of the French Open with a hard-fought 7-6 (7-1) 6-4 6-4 win over Spanish qualifier Jaume Munar.
Djokovic, seeded 20th at Roland Garros, had to overcome a stern test by the 21-year-old despite the straight sets victory.
The former world no 1 blew a 5-2 lead in the first set but came through a tie-break, and his superiority eventually told in the next two sets.
12-time major winner Djokovic has struggled to rediscover his best form since completing a career Grand Slam in 2016 as he’s battled with a series of niggling injuries.
Munar, ranked 155th in the world, fought back in the first set but the more experienced Djokovic kept his composure to emphatically close out the tie-break 7-1.
Djokovic was a little scrappy in the second set, but came back to life in an entertaining final set to see off a spirited effort from Munar after two hours and 18 minutes.
He will face 13th seed Roberto Bautista Agut in the third round after the Spaniard’s 6-4 7-5 6-3 win over Colombia’s Santiago Giraldo.
