Great Britain's Maia Lumsden, Gabriella Taylor and Isabelle Wallace are all through to the girls' singles second round at Wimbledon.
Scotland's Lumsden, 16, beat American second seed Catherine Cartan Bellis 6-7 (4-7) 6-3 6-4 out on court 19.
Taylor, 16, from Southampton, who reached round three of qualifying for the women's event, defeated Canadian Katherine Sebov 7-5 6-1.
Lumsden's fellow Scot Wallace beat Austria's Julia Grabher 6-1 6-2.
Wallace, from Inverness, looked at ease on court number four, using her powerful serve to help take command of the match.
However, there were first-round losses for Glasgow's Anna Brogan, Essex's Joel Cannell, Brighton's Julian Cash, Liverpool's Alexander Sendegeya, Bristol's Katie Swan and Buckinghamshire's Holly Hutchinson.
Hutchinson, 16, came agonisingly close to defeating Seone Mendez of Australia, after coming from a set down to 6-5 up in the third.
But, after missing a chance on match point against her serve, she was broken in the next game before Mendez claimed victory, 6-3 2-6 8-6.
Cannell, meanwhile, was first out on court 19 but was on the back foot quickly after being broken in the first game by Jan Zielinski of Poland, who duly saw out a tightly fought set 7-5 before winning the second 6-4.
Taylor's match against Sebov was as equally matched at first, with both players struggling to hold their serve early on.
The Briton, who trains in Spain and beat former world number 29 Sofia Arvidsson in women's qualifying, then took control of the match with some stunning shots from the baseline.
And in the second she took advantage of a demoralised Sebov to move into the girls' second round.
