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.

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.

Meanwhile, 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.

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.

Earlier, Andy Murray tamed Australia's Nick Kyrgios to also 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.

Men's results:

6-Rafa Nadal (Spain) beat Andrey Kuznetsov (Russia) 6-1 6-3 6-2

Jack Sock (U.S.) beat Borna Coric (Croatia) 6-2 6-1 6-4

Jeremy Chardy (France) beat 17-David Goffin (Belgium) 6-3 6-4 6-2

1-Novak Djokovic (Serbia) beat Thanasi Kokkinakis (Australia) 6-4 6-4 6-4

9-Marin Cilic (Croatia) beat 23-Leonardo Mayer (Argentina) 6-3 6-2 6-4

3-Andy Murray (Britain) beat 29-Nick Kyrgios (Australia) 6-4 6-2 6-3

Kvitova's easy progress

In the women's draw, Czech fourth-seed Petra Kvitova cantered into the last-16 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.
