Sue Barker presents live coverage from the Emirates Arena in Glasgow as Great Britain's first-round Davis Cup World Group tie against the USA reaches its conclusion with the reverse singles matches.

Great Britain are looking to secure back-to-back Davis Cup wins against the USA following their surprise victory in San Diego last year. That win was Britain's first since the days of Fred Perry in 1935. Another triumph would secure a second successive appearance in the quarter-finals for Leon Smith's side. Defeat would leave them facing a play-off to stay in elite World Group.
