Andy Murray praises Great Britain's Davis Cup spirit

Captain Andy Murray has praised Great Britain's "team spirit" following his side's Davis Cup victory over the USA on San Diego clay.

Team GB progressed to the quarter-finals of the event when Murray beat Sam Querrey in four sets on Sunday.

Despite losing the doubles on Saturday, Britain had began the deciding day 2-1 ahead in the best-of-five contest because Querrey had lost a five-set epic to world number 175 James Ward on Friday after Murray had overcome Donald Young 6-1 6-2 6-3.

"We have a really good team spirit," Murray told BBC Sport. "I've known a lot of the guys for a long time.

"There's pressure because you have responsibility for your team-mates but at the same time they've put me in a great position and have won important ties themselves.

"Sam came out playing extremely aggressive, he was very aggressive on my serve. I changed tactics at the beginning of the third set and I was able to dictate a lot of points after that."

Leon Smith's side will now travel to Italy in April, with the winners to play either Switzerland or Kazakhstan in the semi-finals.
