Nadal won the first nine games of the match and when Berdych finally got on the board in the 10th, the Czech player held his left arm up in mock celebration. Berdych came back strongly in the third set and had a set point in the 12th game before Nadal dominated the tiebreaker.
The last time the players met here in 2015 Berdych beat the Spaniard in straight sets to end a 17-match losing streak against Nadal.
It is the 11th time that Nadal has reached the quarterfinals here. He will next play 21-year-old American Frances Tiafoe.
