Top seed Novak Djokovic coasted through to the fourth round of the French Open on Saturday after a straight-set victory over Salvatore Caruso. The Serbian pulled off a convincing win of 6-3 6-3 6-2 against the Italian in just two hours and four minutes to end his run at Roland Garros. "The conditions were very hot today, different to the days before and so tough physically," Djokovic said after the game, under a blazing sun on the Philippe Chatrier court. "I'm feeling motivated, I'm feeling at home." Djokovic, 32, will meet with either borna Coric or Jan-Lennard Struff in the round-of-16. "I have been playing really well this year, and, you know, reaching a second week of a slam is a success," Djokovic told a post-match news conference. But now the real deal starts. So it's going to get only tougher from here." The Serbian is yet to drop a set in the tournament and has rarely had such an easy run into the fourth round at Roland Garros. He will face either Germany's Jan-Lennard Struff or 13th seed Borna Coric of Croatia next. Djokovic is bidding to become the first man in the Open era to win each of the Grand Slams twice. His triumph in this year's Australian Open took him to 15 major singles titles, third only behind Roger Federer (20) and Rafael Nadal (17). "I am grateful to be part of the era with them, because I think they made me the player I am today," Djokovic said. "The success that I had, especially in the Grand Slams, was also due to the kind of a need to improve and to get better to win against these guys. "It seems like it's going to be hard for anyone to kind of do something the same that the three of us did or even better, but you never know what happens."
