Maria Sharapova won a tussle of the top seeds and the last two French Open champions against Li Na, 6-4, 6-3, on Sunday for back-to-back titles at the Porsche Grand Prix.

Sharapova got her ninth victory in the 14th meeting with world number five Li in 1 hour 32 minutes when Li double-faulted on first match point.

Sharapova picked up a winners cheque of 100,000 euros and a flashy blue convertible sports car from the tournament sponsor for her second title of the year.

Li, who won the previous meeting with Sharapova in the Australian Open semifinals, earned 55,000 euros.
