Grand Slam

The Grand Slam is an accomplishment in professional wrestling. It is a distinction given to a professional wrestler who has won four specific championships within a promotion throughout the course of their career. National promotions that recognize this include WCW and WNA. Notable independent promotions include Super Hardcore Wrestling (SHW), InterContinental Championship Wrestling (ICCW), and Riot Federation Wrestling (RFW)

WCW
In WCW (formerly WCCW), the term "Grand Slam" was originally used by Keno Patero to describe himself upon winning the OCW International Championship on April 3, 1983. Patero previously held the OCCW Championship, OCCW Intercontinental Heavyweight Championship, OCCW Tag Team Championship, and the OCCW Magisterian Excellence Championship.

In May 1992, WCW indicated that the Ironman Heavymetalweight Championship was an acceptable substitute for the WCW Magisterian Excellence Championship in the Grand Slam.
