Cameron Diaz is going all out to close the deal with Alex Rodriguez — just ask Alex’s daughter … who looked real cozy with Daddy’s GF at a recent New York Yankees game.

It all went down at Spring Training in Tampa … Cam and A-Rod’s first born, 6-year-old Natasha Alexander, checked each other’s makeup and had some girl talk — we’re guessing stuff like hair, clothes, dad’s $275 million contract.
