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, WNA and EnCW. 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 WCW International Championship on April 3, 1983. Patero previously held the WCW Championship, WCW Intercontinental Championship, WCCW Tag Team Championship, and the WCW Magisterian Excellence Championship.

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

In January 7, 2002, WCW also indicated the Grand Heavyweight Championship is an acceptable substitute for the WCW World Hardcore Championship.
