5: Murray won a major in his 5th final, the same as coach Ivan Lendl.

Plus killer fact to give Murray complete credit, h/t John Crace of the Guardian:
When [Federer, Nadal and Djokovic] won their first major they did so against opponents who had never won a major as well. Murray did so against a man who has won five grand slams and was the defending US Open champion.
