A caged ball fractionation plug for use in a wellbore with a crown engagement having a tapered nose cone and various load ring, slips, slip backups, lubricating spacers and seals can all be slidably engaged to the mandrel. Upon applying pressure, the slidably engaged components can be compressed against each other and the plug can expand and bite into the casing of the wellbore. The caged ball portion of the plug seats the ball internal to the plug to create two separate fractionation zones in the wellbore.
