In the end it was Moya who better adapted to the windy conditions in Miami, snapping Nadal's 22-match win streak over his fellow Spaniards, and cutting loose with increased aggressiveness after getting rolled in the first set.
"The fact that we know each other very well is better for the one who has a lower ranking," Moya told reporters. "In this case, it's me."
Nadal for his part was bothered by an ankle injury sustained last week at Indian Wells.
"For sure I didn't play 100 percent," Nadal told reporters. "But he played very good, too...My physical condition is not my best now, especially after I turned my ankle. I have some problems when I play big points, when I go strong to one side. But that's not a special excuse."
