Murray captured his 26th career tour title, and second of the year having taken the Brisbane crown, after a grueling two hours and 45 minutes.
"Both of us fought hard," Murray said. "Both of us were struggling physically at the end. I was lucky to come through."
It was the second Miami title for Murray, who won the title in 2009 but lost last year's final to Novak Djokovic.
