Angelique Kerber defended her Porsche Grand Prix title with a comprehensive 6-4, 6-0 win over qualifier Laura Siegemund in Sunday's final.

Siegemund made a great start and went 3-0 up in nine minutes, but Kerber recovered and converted three of her five break opportunities to take the first set in 39 minutes. The defending champion started the second set with a break and capitalized on a host of unforced errors from Siegemund — playing her first final in her hometown — to wrap up the match in 81 minutes with her first match point.

It was the ninth career for the second seeded Kerber.

The 71st-ranked Siegemund bettered her previous best finish, a quarterfinal on clay at Charleston this month.
