BERLIN — World number five Caroline Wozniacki needed nearly three hours to break the resistance of second seed Simona Halep of Romania 7-5 5-7 6-2 on Saturday and reach the Stuttgart Grand Prix final for the second time in five years.
The Dane, a former world number one, will play the winner of the second semi-final later on Saturday between American Madison Brengle and Germany's Angelique Kerber as she eyes her second title of the year.
The first game lasted almost 10 minutes, an indication of the slug match that was to follow on the punishing Stuttgart clay.
