WHITE PLAINS, N.Y. -- Jack Sock, Sam Querrey, John Isner, Ryan Harrison and Steve Johnson have been picked for the U.S. Davis Cup team that will face Belgium in the quarterfinals next month in Nashville, Tennessee.
The U.S. Tennis Association announced captain Jim Courier's roster Wednesday. Belgium's team hasn't been made public yet.
Sock is the highest-ranked American man at No. 11 this week, with Querrey 14th and Isner 17th.
The matches will be played on a hard court at Belmont University from April 6-8.
The winner will face Croatia or Kazakhstan in the semifinals Sept. 14-16. The U.S. hasn't been to the Davis Cup's final four since 2012.
The United States holds a 4-0 record against Belgium in the Davis Cup, but the countries last played each other in 2005.
