DEN BOSCH, Netherlands (AP)—Justine Henin defeated Alexandra Dulgheru 6-2, 6-2 Friday to reach the final of the Unicef Open.

Seventh-seeded Andrea Petkovic upset Kirsten Flipkens 6-7 (3), 7-6 (2), 6-4 to advance to Saturday’s final.

The top-seeded Henin capitalized at 2-2 in each set to win the final four games and take the semifinal against fifth-seeded Dulgheru.

The Belgian has not dropped a set in the tournament, her first on grass following a 20-month retirement that started before Wimbledon 2008. The tournament at the All England Club is the only Grand Slam she has never won.

In the men’s draw, Janko Tipsarevic of Serbia upset defending champion Benjamin Becker of Germany 6-7 (5), 6-3, 6-4 in a rain-interrupted match.

He will play unseeded Sergiy Stakhovsky in the final. Stakhovsky beat Xavier Malisse 6-3, 6-4 in the grass-court tournament to advance to his first final of the year.

While Stakhovsky hopes to add to his two ATP titles, the final will be only the second in the eight-year career of Tipsarevic.
