Jamie Murray and Dom Inglot came from behind to win their Davis Cup doubles match and put Great Britain 2-1 up in their tie against Uzbekistan.
The pair recovered from losing the first set to beat Denis Istomin and Sanjar Fayziev 4-6 7-6 (10-8) 6-2 6-3.
It means Britain need victory in one of Sunday's two singles rubbers to win the best-of-five-match tie in Glasgow.
Victory would ensure GB are seeded in the revamped Davis Cup when it starts in February.
Leon Smith's team started the day level with their visitors after victory for Dan Evans and defeat for Cameron Norrie in Friday's singles matches - both of which went to five sets.
Uzbekistan's Istomin, who spent more than four hours on court in his defeat by Evans, showed no signs of fatigue as he and Fayziev pushed Britain's doubles specialists hard.
But after losing the second set in a tie-break having had set point, their belief faltered and that allowed the home team to dominate the rest of the match, claiming victory when Fayziev netted a forehand.
"We were fighting hard in the first couple of sets but couldn't quite find a break," Murray said. "We were so close to being two sets to love down, then we relaxed a bit and played really well in the last two sets."
The tie resumes at 12:00 BST on Sunday when Norrie takes on Istomin before Evans faces Jurabek Karimov.
Tide turns on tie-break
Murray arrived at the tie just a week after winning the US Open mixed doubles title and he and Wimbledon doubles semi-finalist Inglot were favourites to beat an Uzbek pair ranked 448 and 472 in doubles.
But the Uzbeks, who must win the tie to guarantee a place in the qualifying round for next year's new-look Davis Cup, were fired up and broke in the third game to send them on their way to taking the first set.
Neither side could find a breakthrough in the second until Istomin netted in the tie-break to give the British pair the second set. The Uzbeks had held set point at 8-7 before the Britons won the next three points.
Murray and Inglot broke in the third game of the third set thanks to a lovely sliced backhand from the Scot that delighted the packed Emirates Arena.
It had taken them almost two hours to secure their first break of the match - but then they did not look back, finding a rhythm that had been absent until that point.
Another break followed on Fayziev's serve in the seventh game and Murray served out the set.
The fourth set mirrored the third with the Britons clinical on their serves as the errors mounted for the Uzbeks, with the crowd erupting when Fayziev handed the hosts victory with his forehand error.
"It got a little bit dicey but we kept it together," Inglot said. "After we got that second set we were able to settle a little bit and the crowd really got involved and helped us out, so thank you so much."

The first two sets of this match did nothing for the anxiety of British fans, which had heightened considerably after Cameron Norrie's defeat on Friday evening.
Murray and Inglot returned very poorly, and Istomin and Fayziev - who rarely plays far from home, and is ranked outside the world's top 400 in both singles and doubles - had a set point for a two sets to love lead.
But the British pair raised their game in time, and won comfortably in the end. The victory puts the team in a strong position going into Sunday's reverse singles.
Istomin will start favourite to level the tie in the opening match, but Evans should have too much for his opponent in a potential final rubber.
