Andy Murray reached the doubles final at Queen’s as the Briton’s dream return to tennis continued five months after career-saving hip surgery.
He and Feliciano Lopez beat third seeds John Peers and Henri Kontinen 7-5 6-7 (5-7) 10-7.
It was a third match of the day for Lopez, who reached the singles final before heading straight out to resume their suspended doubles quarter-final.
They play Britain’s Joe Salisbury and American Rajeev Ram in Sunday’s final.
After completing a 6-4 7-6 (7-3) win over Britons Dan Evans and Ken Skupski in a quarter-final that had been suspended on Friday for bad light, they stayed on court to play the semi-final.
“I’m very happy to be in the final,” Murray said.
“It was a good match. It was an unbelievable effort from Feliciano. He’s played a lot of tennis in the last couple of games. He’s not young any more!”
Lopez, 37, takes on 34-year-old Gilles Simon in Sunday’s singles final (13:30 BST) before returning to the court for the doubles final with Murray.

More Murray magic
In his three matches at his first tournament since having his hip resurfaced in January, Murray has looked sharp.
Gone is the limp and the grimace that accompanied his obvious discomfort at times pre-surgery.
Instead a relaxed and smiling Murray has returned – and while it is clear he is enjoying simply being back on court, it is also clear that his competitive desire is as great as ever.
A fist pump and roar greeted the ace that sealed the opening set, while in the sixth game of the second set, where he and Lopez were 15-40 down at 1-4, he unleashed a fantastic forehand return that was key to them eventually holding serve.
They broke in the following game and took it into a tie-break, where they were just edged out.
With questions over when fatigue might creep in for Lopez – and when a lack of match fitness might begin to show for Murray against two doubles specialists – they drew enough strength to push themselves over the finishing line, sealing victory when the Spaniard’s serve was not returned.
Murray, who has won the singles title at Queen’s five times, will now have the chance to add the doubles crown – five months after a tearful news conference in Australia where he was revealing his retirement plans.
Murray, whose last doubles title was eight years ago in Tokyo alongside brother Jamie, is playing at Eastbourne next week, where he is swapping Lopez for Brazilian partner Marcelo Melo.
The former world number one and three-time Grand Slam singles champion is then scheduled to partner France’s Pierre-Hugues Herbert in the doubles at Wimbledon next month.
But the Scot’s mixed doubles partner is yet to be decided for his return to Grand Slam tennis at the All England Club.
Salisbury & Ram upset Bryan brothers
While all the attention has been on Murray’s return, compatriot Joe Salisbury has flown under the radar and into the final.
The 27-year-old and American Ram claimed a shock 7-6 (7-4) 7-6 (10-8) victory against fourth-seeded American brothers Bob and Mike Bryan in their semi-final.
Bob Bryan, who has won 16 men’s doubles Grand Slams, returned to tennis at the beginning of this year after having the same hip surgery as Murray in 2018.
Salisbury has three doubles titles to his name, winning the most recent one with Ram in Dubai in March.
The pair also reached the Brisbane International final in January.
They are doubles specialists but since Murray and Lopez knocked out top seeds Robert Farah and Juan Sebastien Cabal in the opening round here, that is unlikely to bother the Scot and the Spaniard.

There were understandable signs of fatigue in Lopez after his three-set singles semi-final win, but with Murray alongside – bursting with energy and intent – he was able to rouse himself to win a third match of the day.
It was a chilly evening and Lopez had eaten very little for several hours. The pair lost their way at times in the second set, but were not to be denied in the match tie-break.
What a week this has been for Murray, who on Sunday has the chance to win his first doubles title for eight years.
And what a week for Lopez: a 37-year-old wildcard, with a chance on Sunday to do the double.
