The Murray brothers and an Argentine duo moved Britain and the South American country to within one victory of the Davis Cup final on Saturday.
Before a raucous crowd in Glasgow, Andy Murray and his brother Jamie led Britain to a five-set victory against Lleyton Hewitt and Sam Groth of Australia on Saturday to take a 2-1 lead in their semifinal.
The Scottish brothers enjoyed vociferous home support in Glasgow but had to come from a set down to win 4-6, 6-3, 6-4, 6-7 (6), 6-4, having wasted a set point in the fourth set.
"To come back from the disappointment of that fourth set, we kept fighting hard and we stuck together, like brothers should," Andy Murray said.
