Katie Boulter reached the second round of the Wimbledon girls' doubles after beating Evgeniya Levashova and Seone Mendez with partner Ivana Jorovic.
Brit Boulter and Serb Jorovic, both 17, were runners up at the 2014 Australian Open and won convincingly, 6-3 6-1.
Elsewhere, Emily Arbuthnott and Holly Hutchinson won their all British first-round match against Emily Appleton and Eden Richardson, 6-3 6-4.
Freya Christie and Isabelle Wallace are also through after a walkover.
Boulter, through to the third round of the girls' singles, looked at ease on court with Jorovic, playing with a smile on her face throughout the match.
And the relaxed attitude saw the pair pull away from their opponents in the second set, winning the final game to love for safe passage.
British pair Anna Brogan and Harriet Dart were on course to join them in the next round after winning their first set against American Usue Maitane Arconada and Hungarian Fanny Stollars, 6-4.
However, they could not keep up that form, losing the next 6-1 and a nervy third 6-4, with match point coming when Brogan failed to connect properly to defend a smash shortly after they had scuppered a chance to break back.
Maia Lumsden and Gabriella Taylor, both through to the singles third round, lost to Jaqueline Adina Cristian and Elena Gabriela Ruse, while Jodie Anna Burrage and Anastasia Mikheeva are also out.
In the boys' event, Jamie Malik and Rhett Purcell were beaten in three sets after a combative and admirable display against seventh seeds Petros Chrysochos and Nino Serdarusic, 6-4 3-6 6-3.
Julian Cash and Alexander Sendegeya also lost in three sets against third seeds Orlando Luz and Marcelo Zormann.
They had kept pace with the Brazilians until they were broken in the sixth game of the third set, and their opponents never looked back.
Jay Clarke and Marcus Walters and Joel Cannell and Max Stewart also fell at the first hurdle.
