Ashleigh Barty and Daria Gavrilova have lived up to their Wimbledon seedings to give Australia a flying start to the women's singles in London.
Barty overcame first-round butterflies to finally break her main-draw duck at The All England Club with a 7-5 6-3 win over Swiss Stefanie Voegele.
Gavrilova was equally impressive in seeing off American lucky loser Caroline Dolehide 6-2 6-3 in little more than an hour.
Barty had taken care of Voegele comfortably in straight sets en route to the title in Nottingham only two weeks ago.
But the world No.93 threatened to make life difficult for Barty as the errors flowed from the Australian No.1's end.
Barty dropped her opening service game of the match on a double-fault, hit straight back to level at 1-1 only to falter again in the seventh game and fall 5-3 behind.
The 17th seed held her nerve, though, to reel off eight consecutive games to snatch the set and then race to a 4-0 lead in the second.
It was all over after 77 minutes as Barty rammed down her seventh ace to book a second-round meeting with either former finalist Eugenie Bouchard, who qualified this year, or British wildcard Gabriella Taylor.
Seeded 26th, Gavrilova had been slated to play good friend Zarina Diyas, only for the Kazakh to withdraw injured on match eve after failing to recover from an on-court tumble during a match last week against Samantha Stosur in Birmingham.
Gavrilova had conceded it would have been "tricky" facing Diyas and looked to enjoy the change of opponent.
She broke the teenaged world No.109 in the opening game of the match and then again in the fifth game to storm through the first set.
There was no let-up in the second set, with Gavrilova putting away 19-year-old Dolehide in 67 minutes to book a second-round date with either Stosur or China's Peng Shuai, who were also in action on Tuesday.
