Henin, the tournament's top seed, was a 6-2, 6-2 winner over Dulgheru. She didn't drop serve and four of the 17 points she lost on serve came on double faults. She won nearly as many points (27-25) on Dulgheru's serve than Dulgheru did.
Seventh-seeded Andrea Petkovic needed more than 2 1/2 hours to win her semifinal, edging Kirsten Flipkens 6-7 (3-7), 7-6 (7-2), 6-4. Petkovic converted all five break-point situations she forced on Flipkens.
Henin and Petkovic will meet Saturday with the tournament title and $37,000 at stake. They have never before played each other in a WTA event.
