Brit Jamie Murray is into both the US Open mixed doubles final and the men's doubles semi-final, after securing two victories in one day.
Murray partnered fellow Brit Neal Skupski in the quarter-finals of the men's doubles against American pair Jackson Withrow and Jack Sock.
Murray, who won the title in 2016 with Bruno Soares, and Skupski dropped the first set but came back to win 4-6 6-1 7-6 (4).
The US Open is only Murray and Skupski's second Grand Slam outing as a doubles pairing, having exited Wimbledon in the first round in July.
They will face top-ranked Colombians Sebastian Cabal and Robert Farah, the Wimbledon champions, in the last four.
Cabal and Farah beat another Briton, Luke Bambridge, along with Japan's Ben McLachlan, 6-4 6-4.
Murray then teamed up with American Bethanie Mattek-Sands, with whom he won the mixed doubles title last year, and they beat Samantha Stosur and Rajeev Ram 6-3 6-1 to reach the final.
Murray said: "We were on fire. We didn't give them a chance, I'm really happy to be in the final again."
