United States and Spain seal spots in Davis Cup final eight

Mackenzie McDonald beat Lukas Klein 6-4, 6-3 in the day's opening singles before Brandon Nakashima beat Jozef Kovalik also in straight sets to give the Americans an unassailable 2-0 lead.

It was the second group win for Bob Bryan's team who are missing a host of top singles players including US Open runner-up Taylor Fritz. They also beat Chile 3-0.

Victory for the US also meant Germany qualified for the final eight which will be held in Malaga in November.

Germany and the US play in the final group game on Saturday with top spot at stake.

Spain also booked their final eight spot as they beat France in Group B in Valencia following their hard-fought victory against the Czech Republic on Wednesday.

Roberto Bautista Agut came from a set down to beat Arthur Fils 2-6 7-5 6-3 before world number three Carlos Alcaraz dismantled Ugo Humbert 6-3 6-3 with one match still to play.

"I was pleased with the level I played from the beginning till the last ball. I was really focused," Alcaraz said.

"It was a high level of tennis. I was really, really intense. Probably one of the best matches I've played this year."

Nervy ending for Italy
