The eight-times champion Rafael Nadal produced yet another rock solid performance to beat Argentine Leonardo Mayer 6-2 7-5 6-2 and reach the fourth round of the French Tennis Open.
The world No.1, who is undefeated at Roland Garros since his only loss in 2009, extended his record to 62-1 on the Paris clay having not dropped a set at this year's event.
The Spaniard made only five unforced errors in the first two sets - 10 in total - even though he was broken in the second as world No.65 Mayer showed his claycourt skills.
Nadal ended the contest with a service winner to set up a meeting with unheralded Serbian Dujan Lajovic, who beat American Jack Sock 6-4 7-5 6-3 and also has yet to drop a set.
Meanwhile just one of the top five women's seeds remains at the tournament after fifth seed Petra Kvitova was knocked out by 2009 champion Svetlana Kuznetsova.
