James Ward has been named to make his first Davis Cup appearance for Britain against Lithuania in Vilnius next weekend.
The four-man team for the Europe/Africa Zone Group II tie was confirmed by captain John Lloyd on Tuesday, with the two singles spots handed to Ward and Dan Evans.
British number one Andy Murray chose not to compete in the match, meaning Lloyd's options were Ward, Evans and Jamie Baker, who will travel to Lithuania as a reserve.
Despite being the highest ranked of the threesome at 252 in the world, Ward has had an uneven start to the season, qualifying for the ATP World Tour event in Chennai but losing his last three matches.
Evans featured in Britain's last tie against Poland but was defeated in straight sets in both his rubbers, contributing to Britain's relegation.
Doubles duo Ken Skupski and Colin Fleming, known as Flemski, complete the team as expected.
The pair impressed on the ATP Tour circuit last year but have lost in the first round of their last three events.
Fellow doubles specialist Ross Hutchins has been named as a reserve, despite advancing to two main tour finals already this season and reclaiming the British number one doubles ranking on Monday.
If Britain defeat Lithuania in the tie, which gets underway on March 5, their chances of promotion would be lifted.
However, Lithuanian number one Richard Berankis, ranked 198th in the world, has shown impressive form this year, while none of the British team have a Davis Cup victory to their name.
