Ruthless Sharapova into final
Maria Sharapova remains on course for a hat-trick of Stuttgart titles after dismantling Italy's Sara Errani in ruthless fashion 6-1 6-2.
Sharapova, who won the title in 2012 and 2013, needed just under an hour to see off clay-court specialist Errani in what was a repeat of the 2012 French Open final which the Russian also won.
The 27-year-old Russian raced into a 3-0 lead winning eight of the first 10 points and took the first set in just 27 minutes with some powerful ground strokes.
Sharapova picked up where she left off in Friday's 6-4 6-3 quarter-final win over world No 3 Agnieszka Radwanska and converted six of her eight break points against Errani.
The 26-year-old Italian was never allowed to find her rhythm as Sharapova dominated the second set.
"It's my first tournament on clay and at the start of the week, I set the goal of improving from match to match," said Sharapova. "It went well for me again today.
"I know how good Sara is on the surface and I was extra ready to perform against her.
"She has a lot of experience and really knows how to play, so I had to take care of things on my side of the net."
The Russian, who has never won a tournament three times running, will face former French Open champion Ana Ivanovic in the final.
Ninth seed Ivanovic came through in the battle of the former number ones, seeing off her Serbian compatriot Jelena Jankovic 6-3 7-5.
