Rafael Nadal returns to Spain Davis Cup team, John Isner out for USA

Rafael Nadal will return to Spain's Davis Cup team after a two-year absence for the lower-tier series against Denmark.

It will be the world No 8's second Davis Cup appearance in the last four years as Spain look to secure the win that would keep them in Group One and avoid a relegation play-off against Sweden.

Also called up by coach Conchita Martinez on Tuesday were world No 7 David Ferrer, Roberto Bautista Agut, Fernando Verdasco and David Marrero.

The last time Nadal played in the Davis Cup was against Ukraine in the 2013 World Group play-off in Madrid while Ferrer hasn't played in the Davis Cup in three years.

"We have a spectacular team," Martinez said. "It's always dangerous to play away from Spain, where the conditions will obviously favour the home team."

Denmark picked a hard court for the tie on 18-20 September to try to take away the advantage of the Spaniards, who traditionally play well on clay.

Elsewhere, Davis Cup debutants Jack Sock and Steve Johnson are included in the USA team travelling to Tashkent for their World Group play-off against Uzbekistan.

The pair will be joined by Sam Querrey and Donald Young but the nation's highest-ranked player John Isner has opted not to play as he says he need to rest after the US Open.

There are more debutants in the Germany team as Alexander Zverev and Dustin Brown have been included for the trip to the Caribbean to face Dominican Republic.

The Czech Republic will be without top-ranked player Tomas Berdych for their play-off against India.

The 29-year-old is focusing on the ATP Tour this year so Jiri Vesely, Lukas Rosol, Radek Stepanek and Adam Pavlasek make up the Czech team for the outdoor hardcourt clash in New Delhi.

World No 15 David Goffin will lead Belgium as they bid for a first Davis Cup final since 1904.

Ruben Bemelmans, Steve Darcis and Kimmer Koppejans make up the Belgian team to face Argentina in Brussels.
