Cameron Norrie sealed Great Britain's place in the Davis Cup Finals group stage as his victory over Colombia's Nicolas Mejia gave 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 a final winner-takes-all rubber against 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, after Norrie beat Barrientos on Friday to cancel out Evans' surprise opening loss to the 253rd-ranked Mejia.
