Grigor Dimitrov survived a scare against Albert Montanes to move into the third round at the Miami Masters, beating the Spaniard 6-1 (5)6-7 6-3.
It looked like it would be a comfortable evening's work for the 15th seed, as he wrapped up the opening set 6-1.
However, the world number 59 appeared to find his feet in the second, giving little away on his serve to force Dimitrov to a tie-breaker, which he won to level the match.
However, the 33-year-old was unable to keep up with his opponent in the decider, as he never looked like recovering from an early break.
Dimitrov plays the winner of the match between Kei Nishikori and Marinko Matosevic in the third round.
