U.S. Davis Cup Captain Jim Courier and world No. 20 player Jack Sock

Americans Jack Sock and Steve Johnson won their doubles match in three sets Saturday, sending the United States to the Davis Cup quarterfinals with a 3-0 victory over Switzerland. Sock and Johnson were the bronze medalists in men’s doubles at the Rio Olympics. The American duo beat Henri Laaksonen and Adrien Bossel 7-6 (3), 6-3, 7-6 (5). Switzerland was without the country’s two best players this weekend: 18-time Grand Slam champion Roger Federer and three-time major champ Stan Wawrinka, but that didn’t detract from the fact that the Americans were on fire.
The U.S. will travel to Australia for the April quarterfinals. Australia advanced with a 3-0 victory over the Czech Republic. The Americans are now 158-4 all-time in Davis Cup ties when taking a 2-0 lead. Sock also won a singles match on Friday. Reverse singles will be best-of-three Sunday.
Sock is scheduled to play Laaksonen and John Isner is slated to face Marco Chiudinelli in pairings of each country’s No. 1 and No. 2 players. Captains can substitute up to an hour before the match with the outcome already settled.
“We will be ready to play tomorrow for sure, even though this thing is decided,” U.S. captain Jim Courier said. “I think I can speak for all of us when I say we’re anxious to get down there and battle on. We really want to get out to the semifinals and see what we can do this year.”
