Almagro was up 5-4 and 30-15, but Nadal took the next three points, including a pair of 118 mph service winners.
They went to a tiebreaker, where Nadal pulled ahead 5-1, before dropping three points in a row. But Nadal answered with a cross-court backhand that forced an error and a service winner on set point that brought a yell of "Come On!"
This is what counts for drama in a Nadal match so far. Ferrer's goal on Friday is to create a little more uncertainty.
"It will be tough against him," Ferrer said, "because he's the best player on clay in history."
