Novak Djokovic continuted his smooth progression towards a maiden French Open title with a 6-4, 6-4, 6-4 dismissal of Australian prodigy Thanasi Kokkinakis to reach the fourth round on Saturday.
The world number one from Serbia showed no ill effects from a groin problem he faced during his previous match, ending the tennis lesson on his first match point when teenager Kokkinakis returned a first serve wide.
Kokkinakis had moments of brilliance on court Philippe Chatrier, sometimes bothering Djokovic with his booming forehand, but he never got into his opponent's serve.
Djokovic, who did not face a single break point, will next face either local favourite Richard Gasquet, the 20th seed, or South African 15th seed Kevin Anderson.
Kvitova eases into last 16
Czech fourth seed Petra Kvitova cantered into the last 16 of the French Open with a 6-3, 6-2 win against Romanian Irina-Camelia Begu.
The double Wimbledon champion, a semi-finalist on the Roland Garros clay in 2012, had too much power for the 30th seed, who could not muster a break point on court Philippe Chatrier.
Kvitova made only nine unforced errors in a polished performance, winning the last seven points.
She faces either American 16th seed Madison Keys or Swiss 23rd seed Timea Bacsinszky for a place in the quarter-finals.
Murray tames Kyrgios
Andy Murray tamed Australian wildchild Nick Kyrgios to reach the last 16, winning an entertaining tussle 6-4, 6-2, 6-3 on Court Suzanne Lenglen.
Murray, the third seed, was ultimately too solid for the 20-year-old Kyrgios who played some scintillating shots but fired too many errors to really trouble the Scot.
Kyrgios produced arguably the shot of the tournament in the first set, a winning lob played between his legs as he threatened to make an impression.
But when he wasted a break point midway through the second set with a basic forehand error his challenge faded.
Murray claimed victory with a stunning backhand winner to take his winning streak on clay to 13 and will play either Belgian David Goffin or Frenchman Jeremy Chardy in the fourth round.
Nadal crushes Kuznetsov to reach last 16 in style
Rafa Nadal's attempt to win the French Open for a 10th time picked up pace with a 6-1, 6-3, 6-2 third round demolition of unseeded Russian Andrey Kuznetsov at Roland Garros on Saturday.
The Spanish defending champion, seeded a lowly sixth this year after a run of patchy form, showed the quality that has made him the dominant force on clay for a decade, brushing aside his opponent with relative ease.
He moves into the second week with an unblemished record and seems to be finding his best form in time for a likely quarter-final blockbuster with world number one Novak Djokovic -- the man he has beaten in two of the last three finals.
Before that can become a reality he will have to beat American Jack Sock in the last 16.
"Things are going better," Nadal said on court. "Against (Nicolas) Almagro (in the last round) I played a good match and again today I played well and had positive feelings.
"Fourth round is very good news for me."
Apart from a dropped service game the first set was perfect for Nadal as he overpowered the lightweight Russian.
Kuznetsov did not hold serve until he was 3-0 down in the second set and although he began to make more of a match of it he was outclassed as Nadal improved his record at Roland Garros to 69-1.
