Harriet Dart and Dan Evans were the first two Britons to reach the third round at this year's Wimbledon with contrasting victories.
Dart, 22, battled to a 7-6 (7-4) 3-6 6-1 win over Brazilian Beatriz Haddad Maia to set up an encounter with world number one Ashleigh Barty.
Evans, meanwhile, impressed in a dominant display to oust 18th seed Nikoloz Basilashvili 6-3 6-2 7-6 (7-2).
But British number two Cameron Norrie lost 6-4 6-4 6-0 to Kei Nishikori.
British number one Johanna Konta faces Czech Katerina Siniakova later on Thursday, while wildcard Jay Clarke takes on 20-time Grand Slam champion Roger Federer.
Dart holds nerve to advance
World number 121 Dart knew she would be pushed all the way by Haddad Maia, who had stunned 2017 champion Garbine Muguruza in the first round.
But the Briton made the perfect start, breaking the Brazilian in the first game and holding on until she was two points from taking the first set at 5-4 on Haddad Maia's serve.
But she let the chance slip with a long forehand and wide backhand and was then broken in the next game before finding her range again with a backhand down the line that took the set into a tie-break, which was handed to her by a forehand mistake from the Brazilian qualifier.
Dart, who had never won back-to-back tour-level matches, found herself an early break down in the second and from then on frustration crept in, with the Briton bashing the grass and her shoes with her racquet and muttering to herself stony-faced as it ran away from her.
But she regrouped to break for 2-1 in the third and had time to gather her thoughts when Haddad Maia called on the physio for treatment on her leg.
She won the next four games in a row, with the Brazilian moving awkwardly, and sealed victory on her second match point when Haddad Maia netted a forehand after two hours and 25 minutes.
"I think mentally I'm improving all the time," Dart said. "I think I'm a very fiery type of competitor. I think that definitely shows. I'm such a fighter. I think sometimes my emotions might get the better of me as you probably saw from parts of the match today.
"I think it's really important that I regrouped and I was able to come out on top.
"I'm just so happy to win and so relieved all at the same time."
Evans makes it look easy
Evans has enjoyed a successful grass-court season in the run-up to Wimbledon, winning titles at Surbiton and Nottingham, and has played with confidence here.
The world number 61 has yet to drop a set and was never in danger of doing so against Georgia's Basilashvili, who is at a career-high ranking of 16.
The Georgian was let down by 48 unforced errors, which allowed Evans to make his victory look even easier.
The Briton squandered two match points on Basilashvili's serve at 5-2 and and one in both of the next two games before finally taking the match at the fifth time of asking with an unreturned serve in the tie-break.
The victory put an emotional Evans the furthest he has been in a Grand Slam tournament since returning in April 2018 from a one-year ban after testing positive for cocaine.
"I was pretty nervous it means so much to get through," Evans, who was close to tears, told BBC television. "I just want to win big matches at Grand Slams, that's what I really enjoy."
