Cut roast in half; place in a 3-qt. slow cooker. In a large bowl, combine the remaining ingredients; pour over roast.
Cover and cook on low for 8-10 hours or until meat is tender.
Freeze option: Place sliced pot roast in freezer containers; top with cooking juices. Cool and freeze. To use, partially thaw in refrigerator overnight. Heat through in a covered saucepan, gently stirring and adding a little water if necessary.
