A two-hour rain delay at the U.S. Open didn't throw Canada's Aleksandra Wozniak off her game.
Wozniak reached the second round of the Grand Slam tournament with a 6-0, 6-3 win over Romania's Alexandra Cadantu on Monday.
The 48th-ranked Wozniak, a quarter-finalist last week in a Dallas tune-up event, needed little more than an hour to advance after losing four of her last five opening matches at Flushing Meadows.
The native of Blainville, Que., made it to the third round in 2009.
"Overall, it was the first solid match for me here," Wozniak said. "The first set went fast and then there was a long bathroom break for her.
"She started putting more balls in during the second set. I'm glad I stayed on top of her and won this one. It was nice that it went so fast after the long rain delay. It was so crowded in the locker-room, the lounge, the cafeteria."
Wozniak will next play good friend Lucie Safarova, who beat American Melanie Oudin 6-4, 6-0.
Wozniak swept the first set with ease in less than half an hour against Cadantu, who suffered a 6-0, 6-0 first-round loss to Maria Sharapova at the French Open this year.
The second set was more competitive, with Wozniak recovering from an early breakdown before winning the match on a third match point.
Wozniak fired ten aces and broke Cadantu's serve on five of seven occasions in the victory.
"I'm looking forward to the second round, I'm really focused," Wozniak said. "Last week in Dallas was really hot and humid, and it was pretty hot here, you really sweat a lot on the court.
"But I got used to it last week, everything feels good so far."
Milos Raonic of Thornhill, Ont., will start his men's campaign against Colombian Santiago Giraldo on Tuesday, while doubles ace Daniel Nestor of Toronto and partner Max Mirnyi of Belarus will open against Americans Steve Johnson and Jack Sock.
