Semi-Final - Great Britain v Argentina: Day 3

Sue Barker introduces live coverage of the final day's singles matches in the Davis Cup semi-final between Great Britain and Argentina in Glasgow.

The British team are vying to reach back-to-back finals, having won the competition for the first time in 79 years in 2015. Argentina await their first title but have been runners-up three times in the last ten years and have reached 11 semi-finals out of the last 15. The winners of the tie will face either Croatia or France in the final in November.
