Lisicki defeated fourth-seeded Daniela Hantuchova 6-3, 6-2 by winning 78 percent of the points on serve. It was the second title of Lisicki's career but first since winning at Charleston, S.C., in April 2009. Hantuchova, who was looking for her second championship of the year, fell to 4-8 in WTA finals.
Lisicki collected $37,000 for the victory while Hantuchova won $19,000.
The event was to have ended Sunday but the final was delayed because of rain.
Lisicki, who didn't drop a set in the tournament, jumped to an early lead in the first set Monday and won the final four games of the match. She fired off eight aces and faced only one break point -- saving it.
The German player landed just 54 percent of her first serves but claimed all but two of the points in those situations. She dropped just four points in four second-set service games.
