U.S. captain Jim Courier's roster was announced Tuesday.
It will be Lleyton Hewitt's first Davis Cup competition as Australia's captain. His players for the March 4-6 matches on an outdoor grass court in Kooyong, Australia, will be Bernard Tomic, Nick Kyrgios, Sam Groth and John Peers.
The U.S. and Australia have met 45 times in Davis Cup play, with the Americans holding a 25-20 edge.
The winner of this first-round matchup will face Belgium or Croatia in the quarterfinals in July.
