Kerber, the defending champion in Stuttgart, needed just over two hours to seal her win after Kvitova recovered from losing the first set to win the tight second.

Kerber, the second seed here, dug deep in the third by making the majority of her first serves count to seal the win.

"The great support from the public here was the key," beamed Kerber after her win. "I can feel the same energy from the crowd there was last year, maybe even a bit more. I love winning here — and hate to lose."

In a duel of left-handers, Kerber raced out to a 4-1 lead with two early breaks and although Kvitova, the 2014 Wimbledon champion, pulled things back to 5-4, the German won the first set.

Kvitova used her only break of the second to level before Kerber established control early in the third to build up a commanding 5-2 lead to then win the match.

Dream run continues

Laura Siegemund continued her remarkable week by adding Radwanska to her growing list of scalps, breaking her high-profile opponent five times as she pulled off a convincing 6-4, 6-2 win.

Siegemund had already beaten Simona Halep and Roberta Vinci to reach the last four and she will now fancy her chances of lifting her first WTA title of her career.
