The final was preceded by a minute's applause to the former world heavyweight champion, who died on Friday night at the age of 74 after a long battle with Parkinson's disease and Murray said: "It was a sad day yesterday.
"I watched and read a lot about him. Even over the last day or so, I went on the BBC Sport web page and the first 11 stories were all on him.
"He was clearly just an amazing man. I don't meet loads of famous people, but he's one famous person I would have loved to meet. I'm sad about that, as well."

Britain's newest boxing world champion Tony Bellew told Sky Sports News: "He stood up for his beliefs, he went against the regime at the time, he did all this and didn't care about the fame, didn't care about the money, and that's why he will go down in history.
"I've read books, watched documentaries, and they said Muhammad Ali's got the most famous face in the world. The second most famous face in the world was Elvis."
Distance runner Mo Farah performed a shadow-boxing tribute before and after his 3,000 metres victory at the Birmingham Diamond League meeting.
He said of Ali: "He was a big hero of mine and I send all my condolences to his family and friends."
Ali's final British opponent hailed the "charisma, style and panache" of the man who gave him his greatest night in boxing.
Halifax-born Richard Dunn was living in Bradford when the opportunity of a lifetime presented itself: a night in the ring with Ali at Munich's Olympiahalle.
The pair fought a gripping five-round battle on May 24, 1976 but t here was to be no great upset, Ali knocking down the Yorkshireman twice in the fifth and windmilling his right arm in forewarning of another mighty punch before referee Herbert Tomser stopped the fight.
It was to prove Ali's last fight in Europe and his death brought back memories for Dunn of that Monday night showdown with 'The Greatest'.
"It goes on forever, that night," Dunn said. "I think it was the best sporting moment of my life.
"Even getting there and walking down to the ring and waiting for him to come in was phenomenal.
"The fight went pretty well I thought. Obviously it was a wrong decision to stop it! He was the best man on the night and that was it, I had no arguments with it."
Dunn, president for the last five years of the Scarborough branch of Parkinson's UK - a role he took in honour of his famous conqueror - knows why Ali transcended sport to have such a wide appeal.
"He had charisma, style, panache. He had everything and he knew how to work a crowd, he knew exactly what to do," the 71-year-old told Press Association Sport.
"I'll never forget him. I considered him a friend."
The world will say a final farewell to Ali on Friday, when his funeral procession takes place in Louisville, his home city.
Former US president Bill Clinton and comedian Billy Crystal will deliver eulogies at a service which will be open to the public.
