Andy Murray suffered a scare in the opening round in Mexico as he overcame a first set deficit to defeat Pablo Andujar.
Andujar gave Murray a run for his money after winning the first set, but was unable to hold off the Scot, who eventually won 3-6, 6-1, 6-2.
Murray still looked half asleep, as his opponent raced into a 5-0 lead in the first set, losing his serve on two occasions. the Brit conceded the first set to the Andujar.
The Spaniard also caused problems for world number one Rafael Nadal in the Rio Open last week, taking his compatriot to three sets.
After a lacklustre first set, Murray was irresistible in the second set. He came out of the blocks, as his more aggressive side was on display. Restricted to only one game, Adujar was unable to hold back the onslaught.
Murray closed the set at 6-1, and had very little difficulty winning the third and subsequently, the match. The Brit was pleased with his efforts.
"I had a difficult start, it was 10 minutes in the match and I was down 5-0, but I started to play more aggressively to get the win and hopefully I can have a good week here", Murray said.
"The first set was extremely challenging, he was dictating the points, but later on he was getting tired and put the pressure on him".
Also through to the second round of the competition was top seed David Ferrer who had no trouble overcoming Mikhail Kukushkin, winning in straight sets.
Yesterday's shock result saw number 3 seed John Isner crash out of the competition in a straight sets defeat to Ivo Karlovic. The towering Croat took the American to two tie-breaks winning 7-6 (7-4), 7-6 (7-5).
