Nadal, not expected to flinch against a player in his first-ever Grand Slam tournament, did not with just three unforced errors in a nearly flawless first set.
"I think I played really well the first set," Nadal said. "Then the second set … I stopped a little bit. I played with less intensity. Playing with less intensity equals more mistakes, and that's what happened.
"It was important that the serve was there during the whole match. And, in my opinion, the third set I finished the match playing well again, good forehands down the line. That's the way to keep improving."
As for Murray, playing against the 267th-ranked player in the world, he seemed to string out the third set for the challenge of coming back, trailing 5-1 in the final set before taking the final six games, including the last 23 points in a row.
"It was a good way to finish the match," said Murray after only his fourth match following back surgery in September. "I feel much better than I did two weeks ago and hopefully I'll feel better and better. It's all a process for me. I've never dealt with this before."
