ROME - Canadian Milos Raonic advanced to his first semifinal of the season Friday after a 6-3, 5-7, 6-2 quarter-final win over Jeremy Chardy of France at the Italian Open.
Raonic, from Thornhill, Ont., will next play second-ranked Novak Djokovic of Serbia, who is back on track after a right wrist injury sidelined him last week.
Raonic led by a set and a break at 6-3, 4-3 before losing his serve for the first time in the tournament. Chardy broke again at 6-5 to force a third set on an overcast day at the Foro Italico.
Djokovic, who sat out last week's Madrid Open, overcame a stiff challenge from David Ferrer before grinding out a 7-5, 4-6, 6-3 win. Djokovic double-faulted on his first match point but then won a 38-shot rally before eventually closing it out in just over 2 1/2 hours.
Djokovic is aiming for third Rome title, having won the clay-court event in 2008 and 2011.
Also reaching the last four was Grigor Dimitrov, who 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.
Dimitrov's semifinal opponent will be either seven-time Rome champion Rafael Nadal or Wimbledon title-holder Andy Murray, who were playing later in the last key warm-up event before the French Open starts in nine days.
"It's definitely one of the most memorable days of my life," Dimitrov said upon reaching his first Masters series semifinal. "I'm just a happy birthday boy today."
In women's play, Sara 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.
Errani will next meet either 2007 and 2008 Rome champion Jelena Jankovic or third-seeded Agnieszka Radwanska.
In the other half of the draw, 2008 French Open champion Ana Ivanovic beat 13th-seeded Carla Suarez Navarro 6-4, 3-6, 6-4 and will face either top-ranked Serena Williams or Zhang Shuai of China.
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 was unusually inconsistent, 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."
