Britain's Andy Murray battled past David Ferrer in a gruelling final to win his second Miami title and regain the world number two ranking.
The Scot, 25, saved a match point on his way to winning 2-6 6-4 7-6 (7-1) for his ninth Masters title.
Murray recovered from losing the first five games and survived a Hawk-Eye call at match point down in the final set.
The victory brought a 26th career title and ensured he will pass Roger Federer in the new world rankings on Monday.
It was also Murray's first win at the elite Masters level since be beat Ferrer in Shanghai at the end of 2011, although he has since won Olympic gold in London and his first Grand Slam title at the US Open.
Sunday's final was played in brutal humidity, which contributed to an unusually high 15 breaks of serve and left both men visibly struggling in the latter stages.
"It was such a tough match," said Murray. "It could have gone either way, both of us were struggling physically at the end.
"It's so tough against him. He has a great attitude, he's a great fighter. I am sure we will have more tough matches in the future."
