NEW HAVEN, Conn. (AP) — Marin Cilic won his first ATP Tour event Saturday, beating American Mardy Fish 6-4, 4-6, 6-2 at the Pilot Pen, a U.S. Open tuneup.

Unseeded Caroline Wozniacki won the women's title, her second tournament victory this month, beating top-seeded Anna Chakvetadze 3-6, 6-4, 6-1.

Despite having the crowd against him, the 19-year-old Cilic broke the hard-serving Fish five times, three times in the final set, to secure the win in his first finals appearance.
