The duo overcame Roberto Bautista Agut and Albert Ramos-Vinolas respectively
Rafael Nadal produced another dominant display to race into his 11th French Open quarter-final – LIVE on talkSPORT 2.
The title favourite maintained his record of never having lost to another Spaniard at Roland Garros with a 6-1 6-2 6-2 victory over 17th seed Roberto Bautista Agut.
Nadal, who lost just one game in beating Nikoloz Basilashvili in round three, has dropped only 20 games in the tournament so far.
That is one more than his best-ever record over four rounds, set here in 2012.
Nadal, who celebrated his 31st birthday on Saturday, has looked supremely confident with his forehand this tournament and it was the same again.
He hit 31 winners in the match compared to just 12 for Bautista Agut and clinched victory after an hour and 50 minutes.
Novak Djokovic, meanwhile, avoided more French Open drama with a straight-sets win over Albert Ramos-Vinolas to reach the last eight.
After fighting back from two sets to one down to beat Diego Schwartzman in the third round, the defending champion was no doubt hoping for an easier evening.
Things did not begin promisingly, but after twice fighting back from a break down in the opening set he pulled away to win 7-6 (7/5) 6-1 6-3.
This was Djokovic’s first match at the tournament without Andre Agassi, whose stay was only ever intended to be a short one.
