Santiago: The United States doesn't have home-court advantage against Chile but it's favoured even on Santiago's clay courts this weekend.
The Americans feature world No. 8 Andy Roddick, No. 32 John Isner and the top-ranked doubles team of Bob and Mike Bryan. They also have Jim Courier, a four-time Grand Slam champion, making his debut as captain.
None of the three Chileans playing this weekend are ranked in the top 150 in the world. Fernando Gonzalez, Chile's most accomplished player and a former top-10 star, was out of action with a hip injury.
