(Updates with men's final)
DEN BOSCH, Netherlands, June 21 Thai qualifier Tamarine Tanasugarn defeated French Open finalist and world number nine Dinara Safina 7-5 6-3 to win the Den Bosch Open on Saturday.
Tanasugarn, ranked 85, won her first title on grass after surviving a break in the first set and winning a hard-fought second set in which she saved eight break points.
"One day you play really good, the next day -- I just was not myself on the court," Safina, who reached the final with an easy victory over fellow-Russian and top seed Elena Dementieva, told a packed centre court.
"(Tanasugarn) plays very different, she has some unbelievable angles and just made me go crazy in the mind."
In the men's event, Spanish top seed David Ferrer disposed of unseeded Marc Gicquel of France 6-4 6-2.
World number five Ferrer, who has not dropped a set all week, won his first title on grass and also became the first Spaniard to win the Den Bosch title.
"I never would have imagined winning a title on grass, but I played really good this week," Ferrer said before receiving his trophy. (Reporting by Niclas Mika; Editing by John Mehaffey)
