STUTTGART, Germany – Reigning Australian Open champion Angelique Kerber won her second title of the season at the Porsche Tennis Grand Prix, dispatching qualifier and countrywoman Laura Siegemund, the tournament’s Cinderella story, 6-4, 6-0.

Siegemund had played inspired tennis throughout the week, taking out three Top 10 players – including top seed and World No.2 Angieszka Radwanska – and showed few signs of stopping from the outset of Sunday’s final, twice moving ahead by a break in the opening set.

But Kerber has only lost one completed match since Indian Wells (Miami Open, Azarenka) and continued to press her opponent, who was playing in her first WTA singles final, into increasingly more grueling rallies – exposing her fatigue from eight matches in nine days and a left hip issue for which she took a medical timeout early in the second set.

Though Siegemund finished the match with more winners (22 to 16), Kerber played her counterpunching style to perfection, hitting just nine unforced errors in 80 minutes to win the final 10 games of the match.

It was nonetheless a stellar week for the 28-year-old veteran, who will bound up nearly 30 spots to a career-high ranking of No.42; more importantly, she leapfrogs four of her compatriots to become the No.4 German woman on the WTA rankings – putting her in pole position to round out the national team who can be sent to the upcoming Summer Olympic Games in Rio de Janeiro.

Kerber remains at No.3, but her title in Stuttgart was not only her first career title defense, but the win makes her the fastest player to back up a maiden Grand Slam title since Petra Kvitova, who won the Generali Ladies Linz three months after capturing her first Wimbledon title in 2011.

The doubles final took place less than an hour later, featuring Top 2 seeds, Martina Hingis and Sania Mirza against Caroline Garcia and Kristina Mladenovic.
