Switzerland suffered a schock defeat against the USA in the first round of the Davis Cup played on clay in Fribourg, Switzerland, losing 5-0.
In the first match, Mardy Fish beat Stanislas Wawrinka in a five set thriller 6-2 4-6 4-6 6-1 9-7.
The big surprise of the day came afterwards as John Isner schocked former world no.1 and 16 time Grand Slam champion Roger Federer, beating him 4-6 6-3 7-6 (4) 6-2.
It wasn´t Federer´s day. On the other hand, Isner played a superb match and secured a second and a very crucial point for the US. Federer won the first set in 30 min but Isner came back to level the match at 1 set all. His big serve and solid groundstrokes did a bit of damage on Roger´s game. The turning point in the match came in the third set, as Isner kept his cool and sealed it with a 7-4 tiebreak win.
Federer had a good chance on his hands in the fourth set, but he couldn´t convert three breakpoints on Isner´s serve. That gave the American a big boost and he stormed to a 6-2 set and match win.
The Swiss had to win the doubles to give them a chance to turn the match around and qualify for the next round.
But it wasn´t meant to be as Mike Bryan and Ryan Harrison dismissed Roger Federer and Stanislas Wawrinka 4-6 6-3 6-3 6-3.
Fish and Bryan, playing only for a second time together, were trailing the 2008 Olympic doubles champions for a set and a half. But some unforced errors from Wawrinka on his serve gave them a chance for a comeback. After taking the second set, they were never going to let this one go. With a four set victory, the Americans booked their place in the next round, where they will either meet Canada or France.
The last two matches were only a formality, Ryan Harrison winning in two tiebreaks against Michael Lammer 7-6 (0) 7-6 (4) and John Isner outpowering Marco Chiudinelli 6-3 6-4.
