Britain's Kyle Edmund and Jonny O'Mara will face each other in the third round of the boys' singles after impressive straight-sets victories in round two.
Fifth seed Edmund beat Yoshihito Nishioka 6-3 6-1, while O'Mara upset 11th seed Pedro Cachin 7-6 (7-3) 6-2.
However, there was disappointment for Luke Bambridge and Billy Harris, who both went out of the competition.
And home hopefuls Katie Boulter, Harriet Dart and Lana Rush were all beaten in the girls' singles.
Edmund dominated from the start of his match although Nishioka failed to take any of the four break points he earned in the first set.
He was not given any chances in the second set as Edmund, from Beverley, took it in just 21 minutes.
Scotland's O'Mara played a good tie-break to take the lead over Cachin after a tight first set but broke twice in the second to settle the match.
Bambridge lost 6-4 6-4 to seventh seed and French Open junior champion Christian Garin after being unable to deal with the Chilean's serve. The 18-year-old Nottingham player failed to earn a break point in the entire match and was broken himself in the first game of each set.
Garin was quicker around the court and while the scoreline was close in each set, Bambridge made too many errors.
The 18-year-old is now set to leave the junior circuit and turn his attention to the main tour and told BBC East Midlands Today: "I'm really looking forward to it and I feel like my game could really progress in the men's game."
Harris, believed to be the first Isle of Man player to win a singles match at the All England Club with his first round victory on Monday, lost 6-1 7-6 (7-4) to Italian ninth seed Filippo Baldi.
The only game he won in the first set was the fourth but he played much better in the second, forcing a tie-break before bowing out.
Boulter, from Leicester, levelled her match at a set apiece against sixth seed Elise Mertens from Belgium, but was then broken to love at the start of the decider and ended up losing 6-3 3-6 6-1.
Dart, who lives in London, but trains in Nottingham, also bowed out, losing 6-1 7-6 (7-4) to Croatian second seed Ana Konjuh
Wimbledon's Rush, who had been a break up in the first set of her match against Karin Kennel, eventually went down 7-6 (7-2) 7-5 to the Swiss 11th seed.
