David Ferrer and Andy Murray, the top two seeded players in the Mexican Open, advanced to the second roundwhile American and third-seeded John Isner became the first major casualty of the tournament, losing 7-6 (4) 7-6 (5) to Croatia's Ivo Karlovic.
Ferrer, the favourite in Acapulco, had a convincing 6-2, 6-3 victory over Kazakh Mikhail Kukushkin while Murray overcame a sluggish start and claimed a 3-6, 6-1, 6-2 win over Pablo Andujar, from Spain.
Murray, who played for the first time ever in Latin America, lost his first three service games and fell into a 5-0 hole, but came back strongly to set up a match against Joao Sousa of Portugal.
In the round-of-16, Ferrer, who is trying to win on Mexican soil for the fourth time in his career, will play Spanish compatriot Feliciano Lopez.
Earlier, Karlovic served 15 aces to Isner fired eight in a match between two of the game's biggest servers.
"I'm very disappointed," a visibly upset Isner said after the match. "I wanted to do well in here, is a good surface for me, but I played against a guy who played well against me".
Sousa of Portugal came back to defeat Frenchman Adrian Mannarino 1-6, 6-2, 6-2.
South Africa's Kevin Anderson downed Stephane Robert of France 6-2, 7-6 (7) and will next play America's Sam Querrey. Seventh-seeded Ernests Gulbis had a 6-1, 6-1 victory over Taiwan's Yen-Hsun Lu.
