Andy Murray and Laura Robson have guaranteed Great Britain a second tennis medal after reaching the mixed doubles final at the expense of Germany's Christopher Kas and Sabine Lisicki.
After reaching the men's singles final after defeating Novak Djokovic on Friday, Murray teamed up with Robson for the mixed doubles first in the quarter final against Lleyton Hewitt and Samantha Stosur and then against Kas and Lisicki in the last four.
The British pair beat both pairs via a champions tiebreak, and will face either Victoria Azarenka and Max Mirnyi or Lisa Raymond and Mike Bryan in the final, after Murray takes on Roger Federer in the singles final.
"It's just different, playing doubles it's a different sort of pressure we played really well when it mattered at the end of the super tiebreaks, there's nerves there," Murray said.
"We played really good stuff at the end, we deserved to win that match and I'm really glad we did because had it gone the other way it would have been a really disappointing end to the day. I've enjoyed the whole tournament, and tomorrow is pretty much the perfect end to the tournament for me and I'll try and win both.
"I told her to take her time, and when we won the point to go up 8-6 I said some words she's probably not heard before! It was an emotional end to the match, but she served great and gave the chance to take control of the net, which is what we needed to do," Murray said.
"It's been different to what I normally do, but I've enjoyed the whole event and tomorrow is pretty much the perfect end to the tournament for me, and I'll try to win both."
"It's been incredible, just to playing singles I was pretty happy with that, and before that I thought I was just playing doubles and now I'm playing in all three and we're guaranteed a medal and I couldn't ask for anything else," Robson added.
"For once my serve went in when it mattered and I went for it. We played really well at the end of the tiebreak at the end of both matches. I've been watching everything, just before we went on I watched the guys win rowing and that was really good and hopefully we'll be able to add to that tomorrow."
Having become the first British male to reach a final at Wimbledon for 74 years earlier this month, Murray will now play in his second and third in quick succession, while Robson, 18, will become the youngster player to win an Olympic medal in 20 years.
