AMERICANS VS. NO. 1
This is just the third time that the U.S. Davis Cup team has faced the No. 1-ranked player in the world since the ATP rankings began in 1974. The U.S. Davis Cup team split its two prior meetings against the world's top-ranked player - a loss in the 2008 semifinals in Madrid (Spain's Rafael Nadal) and a victory in the 1992 semifinals in Minneapolis (Sweden's Stefan Edberg). Sam Querrey made his Davis Cup debut against then-world No. 1 Rafael Nadal in that semifinal meeting.
NOT EXACTLY A RIVALRY
This quarterfinal will mark just the second meeting between the U.S. and Serbia in Davis Cup competition. Serbia won the only meeting, 3-2, in the 2010 World Group first round in Belgrade by a Novak Djokovic-led team. Serbia is only one of three countries to have a winning record against the U.S. Davis Cup team. Serbia is playing in the World Group for its sixth consecutive year after making its World Group debut in 2008 with the help of Djokovic. Serbia won its first and only Davis Cup title in 2010.
IDAHO, WELCOME TO THE CLUB
Idaho is the 34th state to host a U.S. Davis Cup tie. The 16 states that haven't hosted are Alaska, Iowa, Kansas, Maine, Mississippi, Montana, Nebraska, New Hampshire, New Mexico, North Dakota, South Dakota, Utah, Vermont, Washington, West Virginia and Wyoming.
ONE ELITE CLUB OF ATHLETES
Since Davis Cup began in 1900, only 137 players have had the privilege of representing the U.S. in the international competition.
TWO TITANIC SURVIVORS
Norris Williams survived the icy waters of the 1912 ship disaster long enough to be rescued, barely escaping both his legs being amputated. Williams, who lost his father in the tragedy, made his Davis Cup debut 14 months later against Australasia in the 1913 World Group final.
Karl Behr also survived the famous sinking of the Titanic. He was a member of the team that lost to Australasia in the 1907 World Group first round.
COW DUNG - REALLY?
Host countries are allowed to select the surface that is used for Davis Cup events.
In Boise, the portable court is a thin mixture of hard rubber, paint, sand and water. It's officially listed as a hard court.
In 1963, India officially used a cow dung court in its battle with the U.S.
The tie took place Nov. 2-3 at the Cricket Club of India in Bombay. The U.S. won 5-0.
"We tried to get cow dung but they wouldn't let us get it in the building,'' U.S. captain Jim Courier joked about the court surface being used in Boise.
The U.S. returned to India in 1994 and played on grass.
No word on whether cows were grazing nearby.
THE LARGEST CROWD
The largest to watch a Davis Cup match in the United States was Dec. 1, 1990, when 18,156 fans watched Rick Leach and Jim Pugh defeat Australians Pat Cash and John Fitzgerald 6-4, 6-2, 3-6, 7-6 to clinch the 29th Davis Cup title for the U.S. at the Sun Coast Dome in St. Petersburg, Fla.
The three-day attendance record of 50,962 was set at the same event.
SUCKING THIN AIR
The Davis Cup is in Boise to take advantage of the Americans' powerful serves and the elevation of approximately 2,871 feet above sea level.
The highest elevation to host a U.S. Davis Cup team? Bogota, Colombia (8,626 feet) in 1974 and 2010. The U.S. also has played in Mexico City (7,240 feet) 14 times.
