USA finally got their first win at the 2012 World Team Cup in Dusseldorf with victory over Japan.
Unable to qualify out of the red group into the championship round, USA's miserable tournament continued when Andy Roddick lost 7-5 7-6(4) to Go Soeda.
However, Ryan Harrison registered the American team's first win when he beat Tatsuma Ito 6-2 7-6(5), and then paired up with James Blake to win their doubles rubber against Ito and Bumpei Sato 4-6 6-0 10-3.
Japan have now lost all three of their ties at the Rochusclub.
Czech Republic and 2011 runners-up Argentina are the only two teams who can top the red group, and their tie kicked off with a 6-1 6-7(2) 6-3 win for Tomas Berdych over Carlos Berlocq.
Defending champions Germany lost their first rubber against Serbia in the blue group as Viktor Troicki defeated German Florian Mayer 7-6(8) 6-3. The winner of that tie will top the group.
Croatia and Russia are playing for pride in their blue-group tie, which began with Croat Ivan Dodig beating Russian Igor Kunitsyn 7-6(0) 6-4.
