United States opens Davis Cup group play by sweeping Chile - ESPN

ZHUHAI, China -- Less than two weeks after his shocking second-round exit at the US Open, Carlos Alcaraz was staring at another upset when a set down in his opening group-stage match for Spain in the Davis Cup Finals on Wednesday.

This time, Alcaraz turned things around -- though he needed some help from his opponent.

The No. 3-ranked Alcaraz clinched victory for Spain against the Czech Republic in Group B on Wednesday when Tomas Machac retired injured with the score at 6-7 (3), 6-1 in Valencia. It gave Spain an unassailable 2-0 lead, with Roberto Bautista Agut having already defeated Jiri Lehecka 7-6 (1), 6-4.

It was Alcaraz's first match since losing in straight sets to Botic van de Zandschulp -- who was ranked 74th -- at Flushing Meadows.

Spain joined the United States, defending champion Italy and Britain in gaining victories on Wednesday.

Brandon Nakashima beat Alejandro Tabilo 7-6 (5), 2-6, 7-6 (3) after Reilly Opelka defeated Cristian Garin 6-3, 4-6, 7-6 (3) to give the Americans a winning 2-0 lead over Chile in Group C in Zhuhai, China.

Those two singles matches lasted in excess of five hours and the U.S. brought in Austin Krajicek and Rajeev Ram for the doubles, which they won 4-6, 6-4, 7-6 (3) against Tomas Barrios Vera and Matias Soto to seal a 3-0 sweep.

The U.S., which has a leading 32 Davis Cup titles but none since 2007, is bidding to reach the quarterfinals for the second time since the Davis Cup Finals were introduced in 2019. In the qualifiers this year, the Americans defeated Ukraine 4-0 on neutral ground in Vilnius, Lithuania.

Italy didn't need top-ranked Jannik Sinner, the newly crowned US Open champion, to beat Brazil in Group A in Bologna.

Matteo Berrettini beat Joao Fonseca 6-1, 7-6 (5) before Matteo Arnaldi gave Italy an unassailable 2-0 lead by beating Thiago Monteiro 7-5, 6-7 (4), 7-6 (5).

Britain also established a 2-0 advantage over Finland in Manchester, England, in Group D thanks to wins by Dan Evans and Billy Harris.

Evans beat Eero Vasa 7-6 (3), 6-2 and Harris, the guy who once lived out of a van while playing tennis tournaments around Europe, defeated Otto Virtanen 6-4, 7-6 (4).

It finished 2-1 for Britain, though, after Virtanen teamed up with Harri Heliovaara to beat Evans and Neal Skupski 7-6 (4) 7-5 in the doubles.

The four groups are playing in four cities this week to qualify for the Final 8 knockout stage to be held in Malaga, Spain, in November. The top two countries in each four-team group will advance.

In opening play on Tuesday, Belgium beat the Netherlands 2-1, Australia defeated France 2-1, Germany -- playing without No. 2-ranked Alexander Zverev -- beat Slovakia 3-0 and Canada defeated Argentina 2-1.
