Second seed Rafael Nadal won 17 games in succession as he coasted into the French Open quarterfinals on Monday with a 6-2, 6-0, 6-0 demolition of Argentina's Juan Monaco.
The defending champion, bidding to become the first man to capture seven Roland Garros singles titles, will tackle fellow Spaniard Nicolas Almagro for a place in the semifinals. Nadal will start his quarterfinal as comfortable favourite as he leads Almagro 7-0 in their series.
Later, Britain's Andy Murray reached the quarterfinals 1-6, 6-4, 6-1, 6-2 win over Richard Gasquet. The fourth seed will play sixth seed David Ferrer of Spain for a place in the semifinals.
Earlier, Ferrer was deafened, but not stirred as he silenced shrieking Spaniard Marcel Granollers with a 6-3, 6-2, 6-0 demolition job.
Ferrer is one of three players yet to drop a set at Roland Garros — and they all happen to be Spaniards.
Compatriot Almagro booked his place in the last eight with a 12-0 sets record at this year's tournament. He kept up the ruthless run with a 6-4, 6-4, 6-4 hammering of Serbian eighth seed Janko Tipsarevic.
Nadal, who celebrated his 26th birthday on Sunday while title rivals Novak Djokovic and Roger Federer were struggling into the last eight, took his career record in Paris to 49-1.
Monaco, the 13th seed, went into Monday's match with solid claycourt form under his belt having captured titles in Vina del Mar and Houston this year.
But he had lost all three previous clay meetings against Nadal, claiming just 10 games in the process, and the 28-year-old was swept aside again by the champion in just one hour and 46 minutes on Suzanne Lenglen court.
Meanwhile in the women's section, defending champion Na Li crashed out, losing her fourth round tie 3-6, 6-2, 6-0 to unseeded Yaroslava Shvedova of Kazakhstan.
After a confident start, Li had a spectacular meltdown in the second set and never recovered, notching 41 errors and ending up broken seven times. Maria Sharapova struggled into the quarterfinals, defeating Czech veteran Klara Zakopalova 6-4, 6-7(5), 6-2 in an error-scarred clash which featured 21 breaks of serve.
Sharapova finished with 53 unforced errors to her opponent's 48 and served up 12 double faults.
In matches carried over from Sunday, Juan Martin del Potro edged past Tomas Berdych in a battle of the big-hitting baseliners, to book his spot in the last eight, winning 7-6(6), 1-6, 6-3, 7-5.
Local favourite Jo-Wilfried Tsonga joined the Argentine with a 6-4, 7-6(6), 3-6, 3-6, 6-4 win against Swiss 18th seed Stanislas Wawrinka.
Both matches were suspended due to bad light on Sunday evening.
There was cheer for the Indian fans as Sania Mirza and Mahesh Bhupathi inched towards their second Grand Slam title together as they progressed to the mixed doubles semifinals after shocking second seeds Kveta Peschke and Mike Bryan 6-2, 6-3 in just under an hour.
