Birmingham, Alabama - James Blake crumbled under serving pressure as Stan Wawrinka handed Switzerland the 1-0 lead over the heavily favoured US on Friday in their Davis Cup World Group first round.
The 16th-ranked Swiss fought back in three hours to secure a 3-6, 6-4, 6-3, 7-6 (7-3) win against Blake, whose game has been off the boil for six months.
"I feel bad about letting the team down," said Blake. "But the team has picked me up many times before. After I beat myself up for a few more hours, I'll be ready to play on Sunday."
