Yasiel Puig Sues: I'm Striking Out With Insurance ... After House Flood

Yasiel Puig was underwater at his Miami mansion when his refrigerator went on the fritz, but he says his insurance company's giving him the high hard one -- refusing to pay up, according to a lawsuit.

The Dodgers stud outfielder says last November the water supply line for his fridge decided to supply water to the rest of the house, causing extensive damage to the 6 bedroom, 5 1/2 bath crib ... in excess of $15k.

In the suit, Puig says he reported it quickly, got a claim number from Lexington Insurance Company ... and even got a partial payment. Puig's problem is his insurance has NOT fully covered him for the damage ... which he says is fully covered under his $2 million policy.

He is not specific about how much Lexington has paid, but it's clearly not enough in his book.
