The four highest-ranked Americans will lead Team USA against Australia in their upcoming Davis Cup quarterfinal which takes place April 7-9 from Brisbane. Jack Sock, John Isner, Steve Johnson and Sam Querrey will make up the USA team.

The Australians, whose captain is Lleyton Hewitt, will be led by Nick Kyrgios as each country looks to advance to the semifinal round. Joining Krygios in singles will be Jordan Thompson while Hewitt will lean on Sam Groth and John Peers for doubles. A notable player missing from the team is Bernard Tomic who is recovering from a back injury that forced him to pull out of this week's Miami Open.

“All the boys are really excited,” Hewitt said. “It should be a great tie against a very strong American side. Nick’s obviously our No1 player and we’ll be relying on him heavily to get us through the tie. He has beaten a lot of quality players since our first-round tie against the Czech Republic, and I feel the court in Brisbane is really going to suit him. He couldn’t be in better form and I really feel that he’s in the right frame to go out there and get the job done.”
