SAN DIEGO (AP) -- Despite an early exit at the Australian Open because of an injured right ankle, John Isner is on the U.S. roster for its first-round matches against Wimbledon champion Andy Murray and Britain.
Isner, who is ranked 13th, quit after dropping the first two sets of his opening match at the Australian Open last week.
Joining him on the American roster announced Monday by U.S. captain Jim Courier are Sam Querrey and the doubles team of twins Bob and Mike Bryan.
The Davis Cup matches are Jan. 31 through Feb. 2 at a temporary court set up in left field at the San Diego Padres' baseball stadium.
