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 headed for 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 was very happy with the way I battled through (the match)," Querrey said. "I fought through the tough points and got breaks in the second, third and fourth sets. I was just happy to get through it."
It was the first time since 2000 that a U.S. team needed to win the fifth match to advance, and the 25-year-old Querrey started fast, breaking Alves in the second game. But Alves, ranked No. 141, responded with breaks of his own in the third and ninth games to take the opening set.
Querrey responded with a consistent array of cross-court winners to control play the rest of the way.
While Isner, the highest-ranked singles player in the tie at No. 16, bemoaned his play, Querrey expressed satisfaction with a straight-set win over Bellucci on Friday and the four-setter against Alves on Sunday.
U.S. team captain Jim Courier had special praise for the 20th-ranked Querrey.
"Sam faced some adversity at the end and played a great tiebreaker to get past not closing it out on serve," Courier said. "Those are learning moments for a player, things you can draw on later on in your career. Today is a good day for Sam and our team in a lot of ways."
Querrey was especially effective with his serve. He finished with 26 aces, compared to one for Alves, often clocking 120 mph or faster. When Alves was able to return a serve, it often was with little pace, enabling Querrey to eventually hit winners.
"I fight for all the match, all the match," the 30-year-old Alves said. "My ranking is 145, something like this. I play two guys under 20 in the world. I think I play great tennis here."
Isner got off to a fast start in the first match of the day, then went on to a 2-6, 6-4, 6-7 (7), 6-4, 6-3 loss to the 25th-ranked Bellucci.
The left-handed Brazilian overcame Isner's powerful serve with a strong display of groundstrokes that kept the 6-foot-9 American off balance. He played his best tennis in the second part of the match, breaking Isner in the 10th game of the fourth set and then the eighth game of the fifth set.
A dejected Isner said he needed to improve both his mental frame and his play on the court.
"This hurts a lot. I could have won this match," he said. "I just couldn't quite win the big points. It's almost like I wanted it too badly."
At Pattaya, Thailand, second-seeded Maria Kirilenko of Russia won the Pattaya Open on Sunday by coming from a set down to beat Sabine Lisicki.
Kirilenko dominated a third-set tiebreaker to defeat the fifth-seeded German 5-7, 6-1, 7-6 (1). It was the 15th-ranked Kirilenko's sixth WTA title — and her first since 2008.
