Jamie Murray will reach No. 1 in the doubles rankings next week, becoming the first British player to top the ATP rankings.
Despite falling in the first round of Miami, Murray became guaranteed to move in front of Marcelo Melo when the world No. 1 was defeated in the second round.
Murray, who had been on the cusp of No. 1 the previous week, said on social media that his defeat the night before left him wondering if he would ever get there.
"Today, driving in the car, my phone started to go crazy," he said.
