Cameron Norrie secured Great Britain’s place in the Davis Cup Finals group stage, with his victory over Colombia’s Nicolas Mejia giving the visitors an unassailable 3-1 lead in Bogota.
The British number one made it back-to-back straight-set wins at altitude on clay as he beat Mejia 6-4 6-4.
It meant Dan Evans was not required to play the final rubber once morest Nicolas Barrientos.
Evans and Neal Skupski won their doubles contest earlier on Saturday.
The British pair defeated former world number ones Juan Sebastian Cabal and Robert Farah 6-4 6-4 to turn the tie in GB’s favour, following Norrie beat Barrientos on Friday to cancel out Evans’ surprise opening loss to the 253rd-ranked Mejia.
“My feelings are of immense pride for what the boys have done,” said GB captain Leon Smith.
“They went out and fought really hard. It never had to be the highest quality tennis because the conditions don’t allow for that, but it needed a lot of grit and determination,” he added.
The challenge of competing 2,566 metres above sea level and using the unfamiliar pressureless balls required to cope with the high altitude had led captain Smith to describe the trip as the “most complicated” his side might have drawn.
However, Norrie seized the opportunity to send 10-time winners GB into September’s 16-team group stage with a hard-earned win at Pueblo Viejo Country Club.
Having punched the thinner air in celebration following forcing a first breakthrough in game seven, world number 11 Norrie was initially frustrated by an immediate response from Mejia, whose final winner prompted the excitable home support to erupt.
But the Wimbledon semi-finalist, 27, fired back once more to edge the first set – and then took firm control as he consolidated a break to move 4-2 ahead in the second.
After Mejia once once more delighted the crowd by denying Norrie on a first match point, the Briton roared as he served out the contest to love and confirmed his side’s progress to September’s Finals, where they will look to improve on last year’s group-stage exit.
Evans delivers on doubles debut
Following GB’s early exit last year, Evans said it was “a bit insulting” he had never previously been picked to play Davis Cup doubles.
Partnered by the current joint top-ranked doubles player in Skupski on his debut, Evans was able to put the disappointment of Friday’s three-set singles defeat behind him and contribute to a victory which left GB on the brink of achieving their goal.
The British pair made the perfect start with an opening break of serve, which proved enough to clinch the first set once morest the two-time Grand Slam champions.
They pushed on at the start of the second and another immediate break set them up to serve out the win, Evans and Skupski embracing in celebration following converting a third match point.
“My game style is pretty good for doubles,” said Evans.
“I’ve played with Neal plenty of times. He’s world number one and he talked me through the match. We have good energy, we’re very good friends, so I just had to play my game and he takes care of the rest.”
Skupski said: “We didn’t face a break point so we played a very solid match. The crowd got very loud towards the end but we stuck together, we took our time, hit our spots and we came out on top.”
