JACKSONVILLE, Fla. - The United States was in trouble when Sam Querrey began his Davis Cup match against Thiago Alves on Sunday. A few booming serves later, the Americans were in the quarterfinals.

Querrey beat Alves 4-6, 6-3, 6-4, 7-6 (3) to give the U.S. a dramatic 3-2 victory over Brazil, stepping up after teammate John Isner lost to Thomaz Bellucci to send the countries to the deciding fifth match.

"I fought through the tough points and got breaks in the second, third and fourth sets," Querrey said. "I was just happy to get through it."

Canada is in the Davis Cup quarterfinals for the first time. It defeated a five-time champion Spanish team missing Rafael Nadal, David Ferrer and Nicolas Almagro because of injuries and fatigue. The U.S. will host Serbia in the next round in Boise, Idaho, April 5-7. The other three matchups are France-Argentina, Canada-Italy and Czech Republic-Kazakhstan.
