World number eight Andy Roddick and 18th-ranked Sam Querrey will represent the United States in a first-round Davis Cup tie against Chile next month, captain Jim Courier said on Thursday.
Number 24 John Isner and the world's top-ranked doubles team of Bob and Mike Bryan will also make the trip for the March 4-6 claycourt event at the Estadio Nacional in Santiago.
The Americans hold a 4-0 record over Chile in Davis Cup competition.
"All of the US players are committed to the goal of winning the Davis Cup and our first step is to go to battle in Santiago," Courier, who was named US Davis Cup captain in October, said in a statement.
"We expect a tough weekend of matches with our Chilean counterparts and look forward to the challenge," he added.
The 28-year-old Roddick, with a 31-11 record in Davis Cup play, returns to the team for the first time since the first round in 2009.
