Andy Roddick led the United States into the Davis Cup quarter-finals on Sunday as five nations clinched their places with a rubber to spare in their first-round ties.

Spain, France, Germany and Sweden, who like the U.S. have all won the trophy at least once in the last 14 years, also booked their places in the last eight.

Roddick came from one set down to beat the Czech Republic's Tomas Berdych 4-6 6-3 6-2 7-6 to give the U.S. an unassailable 3-1 lead in their tie in Ostrava.

The world number four beat Ivo Minar and Berdych claimed victory over James Blake in Friday's singles while the Bryan brothers Bob and Mike won Saturday's doubles.

All eight ties were still alive going into the final day, the first time that has happened since the world group was introduced in 1981.

The Americans meet Spain, who overcame Switzerland 3-2, in the quarter-finals in April.

Fernando Verdasco put Spain through for the first time in three years by beating Swiss rookie Stephane Bohli 6-3 6-3 6-2 in Geneva.

By April the Spanish should have world number two Rafael Nadal back on the team following his late pullout with a thigh muscle strain shortly before the start of Friday's opening rubber.

Tommy Haas sealed Germany's place in the quarter-finals when his crushing 6-2 7-6 6-4 victory over Croatia's Ivan Ljubicic gave the three-times champions a 3-1 winning lead.

Germany, who won the last of their Davis Cups in 1993, will go on to face either Belgium or Australia in the last eight.

Robin Soderling outlasted Max Mirnyi 6-7 7-5 6-7 7-6 6-3 to clinch victory for Sweden against Belarus.

Soderling's epic victory after four hours of high-octane tennis sent the Swedes into a quarter-final against the winners of the tie between Austria and last year's runners-up Argentina.

Richard Gasquet beat Andrei Pavel 6-3 6-2 7-5 to give France victory over Romania and send the French into a quarter-final against either holders Russia or Chile.
