Samantha Stosur survived a challenge from Russian Elena Vesnina on Monday to progress to the second round of the US Open tennis championships in New York.
The Australian won 3-6 7-6 (7-2) 6-1 at Flushing Meadows.
Stosur trailed by a set and a service break, but recovered to book a second-round meeting with fellow Aussie Anastasia Rodionova, who defeated Serb Bojana Jovanovski 7-5 6-4.
In the men's draw, Carsten Ball also progressed with a 6-7 (4-7) 6-3 6-3 6-2 win over Canadian qualifier Milos Raonic.
But teenager Sally Peers was the surprise packet for Australia on the opening day.
The 19-year-old backed up her three qualifying wins with a 6-0 6-1 first-round thrashing of Canadian Aleksandra Wozniak.
"To win one round of qualifying, I was stoked with. To win two was amazing and then to qualify and play in a slam was just a dream," Peers said.
"I played a pretty flawless match."
"Now to have won a round, I can't describe it. It's just been really fun taking everything in."
Peers's mother Elizabeth played in the 1981 US Open women's singles, as well as and Wimbledon a handful of Australian Opens.
"She sort of knows what I'm going through so it's great and I can talk to her about it too," Peers said.
"I'm following in her footsteps and she's always been really supportive, as both my parents and my whole family have been."
"I spoke to them at like 4.30am. They were asleep and they just woke to check the result. They find it really hard following live scores (on the internet)."
Peers will meet defending champion Kim Clijsters in a dream matchup on Wednesday.
"Kim Clijsters is one of my idols. I have a picture with her signed. To play against her is just going to be amazing," Peers said.
"To play on centre court would also be cool. I've just got to take the whole situation into account and just enjoy playing against her and enjoy the experience."
"Obviously she's at the top of the game at the moment and has been for some time since she's come back, so it really puts the benchmark to where the level is and it can really teach me a lot."
Sophie Ferguson was the only Australian woman to lose on Monday, the wildcard was defeated 6-4 6-0 by Italian Maria Elena Camerin on her Open debut.
