Britons Naomi Broady, Neal Skupski and Jamie Murray are into the Wimbledon mixed doubles quarter-finals.
Broady and Skupski combined to beat Romanian Florin Mergea and Ukrainian Elina Svitolina 4-6 6-3 6-4.
Murray, whose brother Andy was knocked out of the men's singles on Wednesday, partnered Australian Casey Dellacqua to beat sixth seeds Horia Tecau and Sania Mirza 7-5 6-3 on Centre Court.
The Brits are in separate halves of the draw and could meet in the final.
First Broady and Skupski will face 16th seeds Aisam Qureshi and Vera Dushevina in the last eight, with fifth seeds Daniel Nestor and Kristina Mladenovic awaiting in the semi-finals.
Tenth seeds Murray and Dellacqua play 14th seeds Max Mirnyi and Hao-Ching Chan in the quarter-finals with the winner playing 15th seeds Samantha Stosur and Nenad Zimonjic in the last four.
"A lot of people stayed round to watch and it was a nice atmosphere," Murray told BBC Sport after his doubles win.
"A lot of people seemed to be behind us and there were some entertaining rallies.
"We're into the quarter-finals now and we've got a tough match tomorrow.
"I think today was probably the best match we've played together and we'll be a tough team to beat in this tournament."
Skupski and Broady, meanwhile, had been broken in the seventh game of the first set when Broady hit a volley too long off her serve and their opponents duly saw out the set.
The British pair clawed their way back into the match, breaking in the second game of the second set when a Broady lob was not dealt with properly by Mergea and surviving a break point in the fifth game before levelling it.
After breaking in the fifth game of the deciding set they scuppered 10 match points before Svitolina hit the net on their 11th for a win.
The penultimate game lasted over 10 minutes, and included nine deuces and eight match points as Mergea somehow managed to hold on to his serve, before Skupski served excellently to finally see out the match; relief etched on the Brits' faces.
