Montreal - The Spanish world number two has now notched the most wins in the elite series
Rafael Nadal stepped closer to a record 35th Masters 1000 title on Thursday, dispatching Argentina's Guido Pella 6-3, 6-4 on Thursday to power into the ATP Montreal quarterfinals.
The Spanish world number two has now notched the most wins in the elite series, with his 379th Masters victory surpassing Roger Federer by one.
Nadal, an 18-time Grand Slam singles champion, could add another Masters footnote to his epic resume if he successfully defends his Canadian crown for the all-time trophy mark.
He ended the evening with an ace out wide on his fourth match point, moving into his ninth Canadian quarterfinal.
Nadal will play Friday for a semifinal berth against Italy's Fabio Fognini after the seventh seed beat France's Adrian Mannarino 6-2, 7-5.
Dominic Thiem reached the last eight by defeating Croatia's Marin Cilic 7-6 (9/7), 6-4, the Austrian's second victory in two days after waiting five years to break his duck in Canada.
Second seed Thiem, who ousted home hope Denis Shapovalov on Wednesday, faced two break points in the final game against the 2014 US Open champion before securing the triumph on a third match point.
The world number four booked a last-eight clash Friday against eighth seed Daniil Medvedev, who eased past unseeded Christian Garin of Chile 6-3, 6-3.
Third seed Alexander Zverev took some quick revenge by beating Nikoloz Basilashvili 7-5, 5-7, 7-6 (7/5) only 12 days after the German lost to the Georgian in Hamburg.
Zvereva set up a last-eight clash with Karen Khachanov.
The Russian sixth seed earned his spot by ousting Canadian Felix Auger-Aliassime on the youngster's 19th birthday - he shares one with Roger Federer, now 38.
Khachanov administered a 6-7 (7/9), 7-5, 6-3 victory then apologized to the crowd after taking out the last Canadian, but said he thought he got a raw deal from Canadian partisans.
Also advancing to a last-eight meeting were France's Gael Monfils, who beat Poland's Hubert Hurkacz 6-4, 6-0, and Spanish 10th seed Roberto Bautista Agut, who dispatched Frenchman Richard Gasquet 7-5, 7-5.
