Andy Murray breezed into the third round of the men's singles at the Olympic tennis at Wimbledon on Tuesday.
The world number four will also go for gold in the mixed doubles alongside Laura Robson.
Murray had no trouble at all brushing aside Finland's Jarkko Nieminen 6-2 6-4 under the roof on Centre Court but Robson and Heather Watson both lost in the second round of the women's singles.
Robson's brave fight against Maria Sharapova ended in a 7-6 (7/5) 6-3 loss while Watson went down 6-3 6-2 to 14th seed Maria Kirilenko.
Nieminen had been the man Murray scraped past when his back troubles were at their worst at the French Open but there were no such dramas today and he will play Marcos Baghdatis in the last 16 in a rematch of their late-night Wimbledon epic.
Murray said: "I played well today. He didn't start the match that well. Then he definitely played better in the second set. I had the momentum for most of the match. I served well, especially in the second set, I didn't give him many opportunities."
The British team had kept their mixed doubles nominations a secret in the build-up to today's draw but it was Murray and Robson who received a wild card and they will face Czech pair Radek Stepanek and Lucie Hradecka in the first round tomorrow.
Murray insisted he always planned to enter the mixed despite the added workload - he could play eight matches in five days if he gets to the medal matches in both events.
He said: "Like I'm sure a lot of the athletes are saying, it's a once-in-a-lifetime opportunity to try to win a medal at your home Games. I wanted to give myself the best chance at that.
"It's going to be a challenge but if we play well then we've got a chance of winning matches."
Murray and Robson teamed up at the Hopman Cup in Australia in 2010 and 2011, reaching the final the first year, while Murray's only other previous experience of mixed doubles at this level came in his first two appearances at Wimbledon in 2005 and 2006.
The world number four could have played with any of the four British women involved in the Olympic tournament, and the decision to play with Robson was particularly tough on British number one Watson, who recently won a WTA Tour doubles title.
Murray added: "It was a hard decision. But I listened to what the coaches on the team had to say. The decision was made because that's what we felt was the best one to try to win a medal.
"Heather Watson has played some very good doubles this year and is our number one player as well. So it's obviously tough for her. But tough decisions have to be made sometimes."
Robson is looking forward to linking up again with Murray, and she revealed she proposed the two of them should play together when they saw each other at Indian Wells earlier in the season.
The 18-year-old said: "It should be really fun playing with Andy. We haven't played since Hopman Cup last year.
"Most of these teams have been teaming up almost every tournament they can in the last two years to prepare for this so it's definitely going to be tough. But I think we're both pretty good doubles players so who knows?"
Robson certainly took the fight to third seed Sharapova today and led 5-4 in the tie-break, but the Russian played at a very high level and in the end was just too good.
The scoreline was the same as when the pair met in the second round of Wimbledon last season and, although Robson felt she played much better, her primary emotion was frustration that she had not taken her opportunities.
She said: "Right now it's much more disappointment. I definitely had chances. I'm pretty sure it's the same score as last time I played her but today I felt it was much closer on her service games every time. I think she played a lot better than last time."
Watson, whose title came in Stanford earlier this month with New Zealand's Marina Erakovic, was disappointed she had been overlooked for a mixed doubles spot.
She said: "I thought I might have deserved a spot in the mixed because of my ranking, because of how well I've been doing, especially winning a title. I'm upset I didn't get picked but there's not much I can do."
Watson has been in great form, reaching the third round at Wimbledon and becoming the British number one, but Wimbledon quarter-finalist Kirilenko was too solid.
Watson said through tears: "Maria played really well, she doesn't give anything away. She definitely made me play that extra ball and I wasn't aggressive enough.
"It hurts that I've lost. The support was amazing and I feel like I've let everybody down. It was tough, I gave it everything. It's been amazing and I think the reason I'm upset is I wanted it to carry on."
