Andy Murray gained a straight-sets victory against Alejandro Falla at the Miami Masters on Friday.
Murray bounced back from his Indian Wells disappointment with a comfortable win over Falla in the second round of the Sony Ericsson Open in Florida.
The world number four, who had a first-round bye, forced five breaks of serve against the left-handed Colombian and eased to a 6-2 6-3 win in one hour and 16 minutes.
A victory at this event was long overdue for Murray after he suffered straight-sets losses at the first hurdle against Mardy Fish in 2010 and the unheralded Alex Bogomolov Jr last year.
And his mindset coming into the tournament would not have been helped by his surprise second-round defeat by Guillermo Garcia-Lopez at Indian Wells on March 11.
However, the presence of coach Ivan Lendl this week has boosted the Scot following his Indian Wells exit, and the 24-year-old was quickly into his stride against the world number 71.
After holding his opening service game Murray forced an instant break of serve to take a 2-0 lead.
Although Falla hit back in the next, getting back on serve with a break of his own, his respite was brief as Murray broke again to move ahead 4-2 before a third break wrapped up the opening set.
Murray continued to look in good touch at the start of the second set, moving a break up early on to establish a 3-0 lead. However, as before Falla found a way to get back on level terms as he broke the Scot for a second time to trail 3-4.
Again, though, Murray's response was swift and decisive, breaking to love in the next to leave himself serving for the match, which duly did to set up a third-round clash against either Canadian 26th-seed Milos Raonic or French qualifier Arnaud Clement.
Elsewhere in Friday's early second-round matches there was a hard-fought 7-5 7-5 win for sixth-seeded Frenchman Jo-Wilfried Tsonga against Xavier Malisse of Belgium, while the ninth-seeded Janko Tipsarevic of Serbia saw off Argentina's David Nalbandian 7-5 6-3.
Gilles Simon, the 13th seed from France, defeated Spain's Roberto Bautista-Agut 6-4 6-2, 18th-seeded Alexandr Dolgopolov of Ukraine beat Croatia's Antonio Veic 6-4 7-5, while 22nd-seeded Austrian Jurgen Melzer was a winner in three sets against Holland's Robin Haase, 7-6 (7/2) 3-6 6-4.
There were surprises in the women's second round as Spanish wild card Garbine Muguruza Blanco ousted ninth-seeded Vera Zvonareva 6-4 6-3, while the Russian's fellow seeds Angelique Kerber, Monica Niculescu and Kaia Kanepi also bowed out at the hands of Zheng Jie, Aleksandra Wozniak and Silvia Soler-Espinosa respectively.
There were no such troubles for the 15th-seeded Ana Ivanovic of Serbia, who won 6-4 7-5 against
Vania King of the United States, while Slovakian 16th seed Dominika Cibulkova was a 7-5 6-1 victor against Anna Tatishvili of Georgia.
