DUESSELDORF, Germany (AP) — The United States beat the Czech Republic 2-1 at the World Team Cup on Monday despite having to use another doubles team because of an undisclosed injury to top-ranked Bob and Mike Bryan.

The Bryan brothers were replaced by James Blake and Wayne Odesnik, who rallied past Tomas Berdych and Pavel Vizner 0-6, 7-5, 10-8. Blake and Odesnik had split their singles matches in the Red Group on Sunday, with Blake losing to Berdych and Odesnik beating Ivo Minar.

Andy Roddick also withdrew after the shoulder injury that forced his retirement in the Rome Masters semifinals flared again after several days of practice. The sixth-ranked American will miss the French Open but expects to begin his grass-court preparations at Queens in his traditional warmup for Wimbledon.

Eight teams are split into two groups. In a new format for 2008, each series consists of two singles and a doubles played over two days. That ensures each team competes every day during the round-robin period. The group winners play in Saturday's final.

Today and Wednesday, the United States will face Argentina and Sweden will play the Czech Republic in the Red Group. In the Blue Group, Germany will play Italy, and Russia takes on Spain.
