Not taking any chances, United States Davis Cup captain Patrick McEnroe made a switch to the veteran Mardy Fish to replace young Ryan Harrison on day two of the U.S. Davis Cup World Group Playoff with Colombia.

And it worked. Teaming with John Isner, the duo beat Robert Farah and Carlos Salamanca of Colombia, 6-4, 6-4, 6-7 (5), 6-3, on Saturday to give the United States a 2-1 lead in the Davis Cup World Group playoff in Bogotá.

“I just went out and gave my best,” said Farah to reporters in Bogota. “Unfortunately, it was not good enough. They (Fish and Isner) played just too good today. I always knew that Mardy Fish is a great doubles player, but I was surprised just how hard John Isner served. I mean there was some balls that I could not even see. Except for losing, I really enjoyed the experience. The environment was just magical.”

McEnroe took a big risk by leaving the Bryan Brothers off the Davis Cup team. The World No. 1 Doubles team did not make the trip because of the high altitude of Bogota, which is at about 8700 feet.

“The altitude had a lot to do with it (absence of Bryans),” McEnroe said to reporters. “I felt that we might need a couple of extra singles players. Fortunately, Mardy gives us choices as a great singles and doubles player.”

With the win today, the United States needs one win in reverse singles tomorrow to avoid relegation and stay in the World Group.

Fish will go again for the U.S. facing Santiago Giraldo. In the second match, Sam Querrey — or Isner, if the United States captain, Patrick McEnroe, makes a change — will face Alejandro Falla.

Asked if he would be tired Sunday, Fish replied: “Not at all. This is what we train for. That’s why we got here early.”

If Fish wins his match Sunday, it would be the first time an American won three times in a Davis Cup contest since Pete Sampras in 1995.
