ROME -- Rafael Nadal stormed back from a surprisingly poor opening set to edge Andy Murray 1-6, 6-3, 7-5 Thursday and secure a spot in the Italian Open semifinals.
Murray jumped out to a 5-0 lead and won the first set in just 37 minutes with a dominant display, as the Wimbledon champion unleashed a series of winners from just about everywhere on the court.
But Nadal broke early in the second set and took control with a late break in the third to stay on course for his eighth title in Rome.
Still, it was the third consecutive match in which Nadal was pushed to three sets, leaving his clay-court form in question entering Roland Garros, which starts in nine days.
And despite losing in the end, it was a positive performance for Murray, who is still trying to regain his top form following minor back surgery in September.
Nadal's semifinal opponent will be Grigor Dimitrov, while Novak Djokovic and Milos Raonic will meet in the other half of the draw.
Djokovic is back on track after a right wrist injury sidelined him last week. And Serena Williams is cruising again, too, after being slowed by a left thigh problem.
The second-ranked Djokovic overcame a stiff challenge from David Ferrer before grinding out a 7-5, 4-6, 6-3 win and the top-ranked Williams then rolled past Zhang Shuai of China 6-1, 6-3 to stay on course in her title defense.
Williams' semifinal opponent will be 2008 French Open champion Ana Ivanovic, who beat 13th-seeded Carla Suarez Navarro 6-4, 3-6, 6-4.
The other semifinal will pit local hope Sara Errani of Italy vs. 2007 and 2008 Rome champion Jelena Jankovic.
Errani took advantage of a supportive crowd to beat second-seeded Li Na 6-3, 4-6, 6-2 and reach the semifinals for the second consecutive year, while Jankovic eliminated third-seeded Agnieszka Radwanska 6-4, 6-4.
Dimitrov celebrated his 23rd birthday with a win when 36-year-old Tommy Haas retired after losing the first set 6-2 due to a right shoulder injury -- spoiling a matchup between the youngest and oldest players in the top 20.
The big-serving Raonic held off Jeremy Chardy of France 6-3, 5-7, 6-2 on an overcast day with intermittent rain at the Foro Italico.
Djokovic double-faulted on his first match point but then won a 38-shot rally before eventually closing it out in just over 2½ hours.
"It was definitely the most physical match I've had on clay this year," Djokovic said, adding that his wrist is reacting well. "I'm playing with no pain. As long as it stays like this I'll be happy."
The 10th-seeded Errani is attempting to become the first Italian to win the tournament since Raffaella Reggi took the title 29 years ago in Taranto.
The last Italian man to win was Adriano Panatta back in 1976.
Li had won all six previous meetings with Errani but she was unusually inconsistent this time, committing 52 unforced errors to Errani's 21, and appeared rattled by a close call from the chair umpire early in the third set.
Errani celebrated by waving her arms to incite the crowd.
"I did well not to get carried away by the euphoria," Errani said. "It's difficult to describe how it felt at the end. The fans were incredible."
