The Spaniard won a final-round battle with Paula Creamer to secure the title at Highland Meadows Golf Club in Sylvania, Ohio.
They started the day tied for the lead and both carded three birdies over the first seven holes and were still locked together after 13 holes.
Recari birdied a 12-footer on the 14th to take a lead that she would not relinquish.
Recari said. "I did a very good job at the beginning. I stayed calm. I was aggressive. When I felt comfortable I went for it."
