Mix remaining ingredients until blended. Pour half the ketchup mixture over shrimp; turn skewers to evenly coat shrimp with ketchup mixture.

Heat barbecue to medium heat. Remove shrimp from marinade; discard marinade. Grill shrimp 3-5 minutes or until the shrimp turn pink, turning every 2 minutes. Serve with the remaining ketchup mixture.
