Great Britain lead their Davis Cup Finals qualifier after Dan Evans and Neal Skupski beat Colombia's Sebastian Cabal and Robert Farah in Bogota.
Evans, contesting his first doubles match in the competition, and Skupski defeated the former world number one pairing 6-4 6-4 to put GB 2-1 up.
It means British number one Cameron Norrie will have the chance to win the tie when he plays Nicolas Mejia.
Ten-time winners GB are bidding to reach September's group stage.
Norrie ensured the visitors ended the opening day on level terms by defeating Nicolas Barrientos in straight sets, after Evans had lost to the 253rd-ranked Mejia.
