Maria rolls into final

Defending champion Maria Sharapova moved to within one victory of her third straight Stuttgart title after a 6-1, 6-2 win over Italy's Sara Errani in Saturday's semifinal.
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.
"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."
Sharapova, 27, 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.
The Russian picked up where she left off in Friday's 6-4, 6-3 quarterfinal win over world-number three 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.
The statuesque Russian, who has never won a tournament three times running, will face the winner of the all-Serbian semifinal between former number ones Ana Ivanovic and Jelena Jankovic in Sunday's final.
