Joining Isner, who moved up to ninth in the world rankings with his win in Miami, are two-time Olympic medalist Jack Sock, Olympic bronze medalist Steve Johnson, 2012 Olympian Ryan Harrison and 2008 Olympian Sam Querrey. Sock and Johnson won a bronze medal in men’s doubles at the Olympic Games Rio 2016.

Three of the U.S. players are ranked among the top 20 in the world.

On Belgium’s squad are Ruben Bemelmans, Joris De Loore, Sander Gille and Joran Vliegen.

The quarterfinal features a best-of-five format, although matches will be played Sunday even if one team sweeps the first three matches on Friday and Saturday.
