Rafael Nadal once again showed he is the man to beat at the French Open after putting down a brief rebellion from Argentine Leonardo Mayer to win 6-2, 7-5, 6-2 and reach the fourth round despite a sore back on Saturday.

Mayer went for his shots in a tense second set and broke the world No. 1 back for 4-4, only for the Spaniard to regain control in commanding fashion.

"It is for me a very emotional thing when I am on (court Philippe) Chatrier, a lot of memories come to my mind," said Nadal, who made only 10 unforced errors with just two coming in a masterful opening set.
