Leylah Fernandez and Denis Shapovalov are moving on.
The Canadians both won one-sided matches on Wednesday at the US Open.
Fernandez cruised into the third round with a 6-4, 6-1 victory over Thailand's Mananchaya Sawangkaew on Wednesday in New York.
Meanwhile, Shapovalov beat Luca Van Assche of France 6-0, 6-4, 7-6 (7) in a second-round men's match.
Fernandez, seeded 31st, fired two aces with just three double faults while being gifted eight points on double faults from Sawangkaew.
She also converted on six of eight break-point opportunities en route to victory.
Fernandez will next face No. 3 Jessica Pegula, who defeated unseeded Sofia Kenin 6-3, 6-1 in an all-American match on Wednesday.
Pegula is 3-1 against Fernandez, including a hard-court win earlier this year in the third round of the Miami Open.
Shapovalov, from Richmond Hill, Ont., blew a 5-1 lead in the third set and had to fight off a set point in the tiebreak to seal his match.
He next faces No. 8 seed Ben Shelton. The American won the National Bank Open presented by Rogers for the second year in a row last month in Montreal.
Shelton is 4-0 for his career against Shapovalov, including a semifinal win in a third-set tiebreak on an indoor hard-court in Dallas earlier this year.
These are the best showings for Fernandez and Shapovalov at a Grand Slam since both reached the third round at last year's US Open.
Felix Auger-Aliassime returns to the court for his second-round match Thursday against Russia's Karen Khachanov, when Fernandez and Ottawa's Gabriela Dabrowski begin play in women's doubles.
