PARIS- Briefly, and only briefly, Rafael Nadal was in a difficult spot in the French Open quarterfinals.
For the first time in this year's tournament, the eight-time champion dropped a set.
And this had to be on Nadal's mind: His opponent, David Ferrer, could present real problems. Not only is Ferrer ranked No. 5, and not only was he the runner-up at Roland Garros a year ago - to Nadal, of course - but he also beat Nadal on red clay the last time they played each other.

So how did Nadal handle this test? Perfectly. From late in the second set, he won 10 games in a row, and 13 of 14 the rest of the way, to come back and beat Ferrer 4-6, 6-4, 6-0, 6-1, setting up a semifinal Friday against Wimbledon champion Andy Murray.
"At the beginning," Nadal acknowledged, "David was playing with a higher intensity than me."
But once Nadal made a key adjustment - deciding to dispense with his surprisingly off-target backhand as much as possible and instead do whatever he could to use his topspin-heavy forehand - he took over.
After committing 28 unforced errors across the windy first two sets, Nadal had zero in the third, and only three in the last.
"When I was able to hit with my forehand," Nadal said, "I felt that I was in control."
Ferrer, for his part, said that in the latter stages, "I lost my concentration, my focus."
It was Nadal's 33rd consecutive win at the French Open and improved his record in the event to 64-1. His only loss at the tournament came to Robin Soderling in the fourth round in 2009.
The Spaniard, who turned 28 on Tuesday, is not used to facing much in the way of hardship at Roland Garros. So Nadal took what he was able to do against Ferrer as a good sign.
"At the end of the day, I am rather happy to have been able to turn the situation around," said Nadal, who wasn't thrilled to be put on Court Suzanne Lenglen, the second-largest arena, for the second time this year. "I managed to pull through, even though it was complicated."
The route Murray took during his 6-4, 6-1, 4-6, 1-6, 6-0 victory over No. 23 Gael Monfils of France was far more circuitous, finishing right on the cusp of dusk after 9:30 p.m. In front of a crowd loudly pulling for Monfils at Court Philippe Chatrier, Murray was terrific at the outset, mediocre in the middle, then closed on a high.
After a brief discussion with a tournament official over whether there was enough sun to play the fifth set - the Roland Garros courts have no artificial lights - Murray made the whole thing moot. He raced through that set in 21 minutes, winning 24 of 31 points, as Monfils appeared to stop trying.
"Everything happened very fast," Monfils said.
Said Murray: "It was so dark at the end. Thankfully for me, he played a poor fifth set once I got ahead."
Murray will be playing in the French Open semifinals for the second time; he lost to Nadal in 2011. In all, Nadal owns a 14-5 edge in their head-to-head matches.
"I need to recover very well," Murray said, "and try to be especially calm for that one."
The other men's semifinal will be No. 2 Novak Djokovic against No. 18 Ernests Gulbis.
Earlier, No. 4 Simona Halep of Romania and No. 28 Andrea Petkovic of Germany both moved into the semifinals of a Grand Slam tournament for the first time. Thursday's other women's semifinal will be 2012 champion Maria Sharapova against 18th-seeded Eugenie Bouchard of Canada.
Halep beat 2009 champion Svetlana Kuznetsova 6-2, 6-2, and Petkovic defeated 2012 runner-up Sara Errani by that very same score.
A year ago, Halep arrived at Roland Garros ranked 57th. But over the past 13 months, she's won seven titles. Petkovic, meanwhile, is enjoying a resurgence.
She made it to the top 10 in 2011, when she was the only woman to reach three major quarterfinals (although she went 0-3). In late 2012, she hurt her right knee, and her ranking plummeted to 177th last year. But she's worked her way back, and after eliminating Errani, the gregarious Petkovic kissed her racket - something she said she'd never done before.
"I don't know what happened to me. I was just overwhelmed by emotion," Petkovic said. "I had no boy to kiss, so I kissed my racket, right?"
