Düsseldorf - Mardy Fish claimed his first career singles win at the World Team Cup as he beat Andrey Golubev of Kazakhstan 6-4, 6-2 on Tuesday, sending the four-time champion US into a 1-0 lead.

In the Blue group, Florian Mayer handed Germany a 1-0 margin over Spain with his defeat of Marcel Granollers 4-6, 6-4, 6-2. The win leaves the hosts 4-0 so far this week after sweeping 2009 champion Serbia 3-0 to start the competition.
Rome quarter-finalist Mayer, who lost last week to Andy Murray, took a victory in two hours, 20 minutes on his first match point.
"It was all about the fight today," said Mayer, poised to break into the Top 20 from his new 21st ranking. "My legs were tired after Monday and I had too many easy mistakes.
"Two or three years ago I probably would have lost this match. But I've gained a lot of self-confidence recently, winning becomes a habit."
