Maria thru' to semis

Defending champion Maria Sharapova had another tough battle on Friday as she booked her place in the semifinals of the Stuttgart WTA tournament with a 7-5, 4-6, 6-4 quarterfinal win against former world number one Ana Ivanovic.
The 26-year-old Sharapova, who is using the claycourt tournament to help prepare for the defence of her French Open title at the end of May, was again taken to three sets as Ivanovic rallied in the second set.
Having needed three hours to beat Lucie Safarova in Thursday's second round, the statuesque Russian has now played more than five hours of tennis inside 24 hours after needing two hours, 16 minutes to beat Ivanovic.
"It's good to face different styles of playing from different opponents," said Sharapova.
"Ana is a bit more aggressive, while Lucie had a bit more variety in her game yesterday.
"I am happy to get through, but I had to push myself.
"It was a tough battle, it was hard to get my body going again after the last game, but it was good to get another three sets under the belt."
After Sharapova took the first set, claycourt specialist Ivanovic rallied in the second with plenty of aggressive shots on her forehand and is on her way back up the rankings, but lacks consistency.
Sharapova broke Ivanovic twice in the third, in a sequence of three breaks, before her aggressive game finally wore down the 25-year-old Serb, who reached the world number one ranking just after winning the 2008 French Open title.
