Andy Murray admitted Great Britain's Davis Cup win over the United States in his native Glasgow had been a "very emotional" experience after he sealed victory with a straight-sets win over John Isner.
Murray overcame some difficult moments in the first set to secure a 7-6 (7/4) 6-3 7-6 (7/4) triumph at the Emirates Arena and line up a World Group quarter-final home tie against France.
The 27-year-old had set Britain on the way by taking two sets inside 46 minutes against Donald Young on Friday afternoon but the drama was only just beginning.
Murray then watched team-mate James Ward come from two sets down to win an epic tussle with world number 20 Isner before his brother Jamie and Dom Ingol came back from a similar position against Mike and Bob Bryan, the best doubles team of all time, only to fall just short in another marathon tie.
And Murray was proud to have been part of an effort that repeated Britain's win in San Diego at the same stage last year.
The former Wimbledon champion said: "The effort and attitude of everyone in the team was excellent. I feel we deserved to win because of that.
"Everyone fought extremely hard especially when we were behind in the matches, no-one gave up and everyone played every point extremely hard.
"It's a big win. It means a lot to everyone.
"There's a great synergy in the team and that builds the emotion and togetherness. It gives you that extra incentive to perform and fight for every single point.
"I was very emotional the whole weekend. I know the team extremely well, the players and the staff.
"I was proud of them as team-mates and also as friends and my brother of the way they performed and thought in this arena and under that much pressure. All of them did incredibly well. I was proud to be part of their team."
Murray admitted he had felt the pressure a bit too much at the start of the final day's play.
He fought off three break points after two double faults to tie the score at 4-4 and then saved three set points in his next service game, producing aces at crucial moments.
Big-serving Isner hit 12 aces before the tie-break but some excellent backhand slices gave Murray the advantage and a brilliant lob saw him break in the second set.
Murray stayed out of trouble in the third and his mental strength was again on show as he wrapped up the victory.
"I felt a little bit more pressure today to try to close it out and also the way John approached the match made it difficult," he said.
