ROSMALEN, Netherlands -- Nicolas Mahut of France won his first ATP title at the age of 31, playing impeccable serve-and-volley tennis to beat second-seeded Stanislas Wawrinka 6-3, 6-4 in the Topshelf Open final on Saturday.
Mahut's and Wawrinka's match also was disrupted by rain and Mahut -- appearing in his first final since 2007 -- dealt with the interruptions better.
The Frenchman's victory on grass capped a comeback from a career-threatening knee injury that sidelined him for months.
"Six months ago, I was not sure I could play again on the tour and here I am with the trophy," he said.
"I am really proud with the way I played all week," added Mahut, who came through qualifying.
Mahut had to break Wawrinka only twice for the victory, once to take a 5-3 lead in the first set -- with Wawrinka serving a double fault to gift the Frenchman the game -- and again in the third game of the second set.
In the women's final, Halep was a break up at 5-4 when rain forced a 75-minute break, but she came back strong, holding serve to take the set.
She then twice broke Flipkens' serve to race to 3-0 before the Belgian broke back.
But Flipkens had no answer to the powerful groundstrokes from Halep, who easily won her first grass-court title.
Halep clinched her first WTA title last week in the inaugural Nurnberger Versicherungscup, a clay event. She heads to Wimbledon where she faces Olga Govortsova in the first round.
