Bianca Andreescu is heading to the third round of the Italian Open, while fellow Canadian Leylah Fernandez is out of the clay-court tournament after a loss on Wednesday.
Andreescu, from Mississauga, Ont., beat Spain's Nuria Parrizas-Diaz 6-3, 7-6 (4) in the second round.
Later, Fernandez, from Laval, Que., lost 4-6, 6-3, 7-6 (2) to Daria Kasatkina of Russia.
It is Andreescu's third tournament back after being away from the WTA Tour for six months.
It marks the second tournament in a row in which the 2019 U.S. Open champion has reached the third round.
Against Parrizas-Diaz, Andreescu converted on all four of her break points and saved nine of 12 against her.
Andreescu will face Croatia's Petra Martic in the round of 16.
Canadian men Denis Shapovalov and Felix Auger-Aliassime play third-round matches on Thursday.
Shapovalov faces Rafael Nadal of Spain in a rematch of a memorable encounter from last year's Italian Open when the latter player fought off two match points to win.
Auger-Aliassime battles Marcos Giron of the United States.
