In a small saucepan, combine the first nine ingredients. Bring to a boil. Reduce heat; simmer, uncovered, for 20 minutes. Stir in the ketchup, Worcestershire sauce and Liquid Smoke; heat through. Discard lemon.
In a large skillet, brown pork chops in oil in batches. Transfer to a 13x9 inch baking dish coated with cooking spray. Pour sauce over chops.
Cover and bake at 350 degrees for 30 minutes or until a meat thermometer reads 160 degrees.
