Andy Murray completed a fine start to the new season by winning the Brisbane International title.
The world number three successfully defended the title he won last year, edging past promising Bulgarian Grigor Dimitrov 7-6 6-4.
Having beaten the 21-year-old the only other time they had met in Bangkok in 2011, Murray could have been forgiven for being confident but he did not have it all his own way against an opponent ranked 48 in the world.
First-time finalist Dimitrov got off to a storming start, winning 11 of the first 12 points and breaking Murray in game two to go 3-0 up.
But Murray broke back as Dimitrov served for the set at 5-3, then forced a tie-break which he took to love.
Dimitrov blasted a forehand winner down the line to hold serve for 2-2 as the second set went with serve.
A deciding set looked possible when the Bulgarian broke to lead 4-3 but Murray took the next two games to go 5-4 ahead.
With the set back on serve Murray broke once more to retain the title.
"It's his first final. Everyone will agree he played some extremely exciting tennis, it was a very tough match," Murray said.
"He's just changed coaches, started with a new team, so congratulations to them I'm sure they're going to do great things together."
