Andy Murray is into the third round of the Sony Open in Miami despite an early wobble against the world number 67.
After losing the first set 6-3 to Australian Matthew Ebden, he dominated the next two for the loss of just one game, securing victory as the clock approached midnight at Crandon Park.
In his first match since an unexpected split with coach Ivan Lendl earlier in the week, Murray got the contest off to an unsteady start when Ebden broke him at the first opportunity and then held serve to quickly jump in front 3-0 on his way to easily taking the opening set.
After storming through the second set, Murray was broken at the start of the third and flew into a towel tossing rage as he berated himself.
The chastising had the desired result as the sixth seed immediately broke back to get on level terms and raced through the next five games to clinch a convincing victory.
“You do what you do to win a match,” said Murray. “It's not always about how you play or how calm you are on the court, it's about winning the tennis match. That's what matters.
"I won the next six games after that so maybe it nothing to do with it, maybe it helped. I just got on with it and won the match."
The Wimbledon champion was one of a parade of grand slam winners who made it through the second round, including world number two Novak Djokovic and Roger Federer.
He will next face Spaniard Feliciano Lopez, against whom he has a 9-0 record
After a year's absence, fifth seeded Federer celebrated his return to the Miami hard courts with a clinical 6-4 7-6 (4) win over towering Ivo Karlovic while Djokovic launched his bid for a fourth Miami title in impressive fashion, dispatching Frenchman Jeremy Chardy 6-4 6-3.
In other action, fourth seeded Spaniard David Ferrer and ninth seeded Frenchman Richard Gasquet both had straight sets passages to the next round.
Venus Williams registered a straight sets win and Li Na advanced in a walkover.
