Rafael Nadal won his 300th match on clay in style with a 6-1 6-3 thrashing of Italy's Andreas Seppi moving him into the quarter-finals of the Monte Carlo Masters.
Eight-time Monte Carlo champion Nadal became just the 11th man to reach the 300-win mark on clay, taking his superb record in the principality to 50-2.
Fellow Spaniard Carlos Moya, who ended his career with 337 wins on clay, was the last man to reach the 300 mark on the surface.
The world No 1 will now face compatriot and sixth seed David Ferrer in the last eight after he put away Bulgaria's Grigor Dimitrov 6-4 6-2.
"I did what I had to in order to get where I am," said Nadal. "But playing David (Ferrer) is never easy. If you are not at the top of your game you will lose. I'm just glad to be in a quarter-final."
Nadal dropped serve to love in the second set and struggled on serve throughout the match - he says it was due to a bizarre problem with his shorts which affected his second serve, as he could not keep a spare in his pockets.
"The ball comes out of the bottom of them and gets in the way," Nadal told Teledeporte of his unusual wardrobe malfunction. "We'll try to sort it out for the next tournaments but here it won't be possible.
"When you have been doing something the same way for so many years, when there is a change you have to think about it and it makes things a bit more difficult.
"But it's better to do it that way than have the ball popping out of the bottom of your shorts which is quite uncomfortable."
Roger Federer also showed his class on the dirt as he came from a break down in the first set to beat Czech Lukas Rosol 6-4 6-1 for an ATP-leading 26th win of the season, and he will go up against Jo-Wilfried Tsonga in the next round.
Novak Djokovic is the defending champion after ending Nadal's eight-year reign, and he dropped just a single game in his 6-0 6-1 demolition job on Pablo Carreno Busta.
Third seed Stanislas Wawrinka booked his place in the last eight without hitting a ball, as the Australian Open champion's third-round opponent Nicolas Almagro withdrew through injury.
"I woke up this morning with a severe pain in my left foot that prevented me from even walking normally," said Almagro.
"After consulting with the doctor for a long time this morning, we decided together that it was better for me not to play today."
