Sue Barker introduces continued live Davis Cup coverage of Great Britain's World Group first-round Davis Cup tie against the USA, with the focus on the traditional second day doubles match.

Great Britain memorably beat the USA in this round last year, booking a place in the quarter-finals for their first time in 28 years. Andy Murray was rested for the doubles by coach Leon Smith with GB leading 2-0 after the opening day. Instead, it was left to the US's world number one doubles pairing of Bob and Mike Bryan to take centre stage. They defeated Colin Fleming and Dominic Inglot in four sets to reduce the States' arrears to 2-1 and set up a tense finale.

Commentary comes from Andrew Castle, John Lloyd and Jonathan Overend on what could be a vital match ahead of the final day. Show less
