Novak Djokovic barely broke sweat on his way to a 70th win at the French Open against Ricardas Berankis on Thursday.
The world No 1 polished off a 6-1 6-2 6-2 victory in just an hour and 23 minutes and has dropped only 10 games in his two matches so far.
The Serbian, who next faces lucky loser Daniel Elahi Galan, said: "Grand Slams are obviously the biggest tournaments in our sport. Historically, they count the most. So, of course, winning that many matches in each slam is a great achievement, and of course it makes me proud, makes me happy.
"Over the two weeks it takes a lot of energy and effort to invest into winning a Grand Slam. It's kind of a confirmation for me that I have been able to play my best tennis throughout my career in the biggest tournaments."
The opening set was done and dusted in just 22 minutes as Djokovic won the last 10 points while the second set was only marginally more competitive.
Berankis, ranked 66th, needed courtside treatment on his back before the start of the third set but got back to his feet to endure more punishment from the clinical Serb.
Djokovic, bidding for his second French Open crown and 18th Grand Slam title, has dropped 10 games in two rounds so far and took the opportunity to practice his drop shot on numerous occasions. He finished things off after 83 minutes with his 10th ace.
He has now tied Roger Federer for match wins at Roland Garros and trails only Rafael Nadal.
Spain's Roberto Carballes Baena reached the third round at a Grand Slam tournament for the first time by beating ninth-seeded Denis Shapovalov 7-5 6-7 (5-7) 6-3 3-6 8-6 in a match that lasted five hours.
Shapovalov has not been impressed with the organisation of the tournament in general and hit out at the supposedly-secure player bubble as well as the scheduling.
He said: "Honestly I think they're not doing a good job. There's really no bubble, especially in the second hotel, I heard. Scheduling is absolutely awful. After a five-hour match I have to play doubles now. It's just complete trash scheduling."
World No 101 Carballes Baena will next play 18th-seeded Grigor Dimitrov, who was a 6-4 7-6 (7-5) 6-1 winner against Andrej Martin.
Fifth seed Stefanos Tsitsipas had to recover from two sets down to win in the first round but was much more impressive against Pablo Cuevas, winning 6-1 6-4 6-2 with an exuberant performance.
Karen Khachanov did not allow a Twitter spat with Nick Kyrgios to derail him as he ground out a 6-1 6-7 (4) 7-6 (7) 7-6 (2) victory over Jiri Vesely.
Khachanov weighed in after Kyrgios strongly criticised Mats Wilander for claiming Andy Murray should not be taking wild cards and received a verbal serve from the Australian.
Khachanov said: "I don't have any problem with Nick. I always said that I respect him. I don't know why he acts sometimes the way he acts. I wanted to be more polite just to explain also my opinion. But maybe just I want to let it go and that's it."
