- Ana Ivanovic overcame illness and nerves as she outlasted French Open champ Maria Sharapova 6-2, 5-7, 7-5 on Saturday to reach the final of the WTA Tour's Cincinnati event.
The former world number one will face off for the title when she plays Serena Williams on Sunday.
Ivanovic led by a set and 5-2 but fell victim to nerves as the scrambling Sharapova fought back.
Sharapova levelled the sets at one each as she clinched the second set with an ace but Ivanovic finally came through in just under three hours.
"Up a set and 5-2, I got tight," said Ivanovic. "I was not moving my feet. She's a great champion and she used her opportunities.
"It was very important for me to get my composure back in the third set.
"My emotions were all over the place. There were a lot of breaks in the final set. Maria is a fighter and never gives up. But I stayed calm."
