#4 Eddie Guerrero won the SmackDown Royal Rumble
Eddie Guerrero competed in the 2004 Royal Rumble match which was won by Chris Benoit, which guaranteed him a shot at a world title at WrestleMania. The only problem was, Benoit was a SmackDown superstar and he decided to use a loophole to join Raw and challenge for the World Heavyweight Championship. This left the SmackDown WWE Championship picture wide open.
SmackDown's then General Manager Paul Heyman, being the creative genius that he is, decided that SmackDown would air the first-ever network television 15-man Royal Rumble match to declare a new No.1 contender for the WWE Championship. Notable superstars in the match included Kurt Angle, The Big Show, John Cena and Rikishi.
The match was ultimately won by Eddie Guerrero. Eddie, who was now a singles competitor, went onto challenge for the WWE Championship at the SmackDown exclusive No Way Out 2005 pay-per-view. The 15-man Royal Rumble win will go down as one of Eddie's greatest moments, as it begin his road to the top of the WWE.
