This fight is for the WBA featherweight title. But there are at least three WBA world champions at featherweight.
Undefeated Indonesian superstar Chris John has been the WBA featherweight champion for over a decade. But the WBA made him a "super" champion in 2009.
Javier Fortuna won the vacant WBA featherweight title in December of last year on the Manny Pacquiao-Juan Manuel Marquez IV card when he beat Patrick Hyland by unanimous decision. But on that exact same night, Nicholas Walters won a different version of the WBA featherweight title in Jaimaca, when he beat Daulis Prescott by Round 7 TKO.
Meanwhile, Jesus Marcelo Andres Cuellar captured yet another version of the WBA featherweight title by unanimous decision over Claudio Marrero last August.
Fortuna has since moved up to super featherweight, but that still leaves Walters and Cuellar, along with John, as reigning WBA featherweight champions of the world.
Alphabet soup titles aside, Walters hasn't beaten anybody to deserve being called a legitimate world champion. Alberto Garza is a respectable journeyman fighter, but beating him still won't make anybody think Walters is the man at 126 pounds.
Still, this has potential to be a very good fight, and it's definitely a relevant fight at featherweight. If Walters can keep knocking out opponents, Top Rank and HBO will find programming space for him.
