The two-time Dominican Olympian Payano began his path towards another world title with a stoppage of Isao Gonzalo Carranza in January, after first becoming a champion via a technical decision over Anselmo Moreno in September 2014. The accomplished amateur won gold at the 2006 Central American and Caribbean games with victories over McJoe Arroyo and Yoandris Salinas. He defeated Jundy Maraon, Jose Silveria and Luis Maldonado on the way to his title shot and engaged in a pair of exciting fights with Rau'shee Warren that saw him defend his title in August 2015 and lose in June 2016.

A pro since 2009, the 26-year-old Santiago had won ten consecutive bouts before dropping a decision to Jose Cayetano in his last contest. The Phoenix-native defeated Gustavo Molina, Javier Gallo and Antonio Tostado Garcia in 2015 and and has also taken down once-beaten fighters Alex Rangel and Hanzel Martinez. He will make his 2017 debut against one of his most experienced foes to date in Payano.

An amateur standout who won a 2012 Amateur National Championship the same year as his Olympic run, Herring fights out of Cincinnati and is originally from Coram, New York. The 31-year-old won his first 15 pro fights including triumphs over Luis Eduardo Florez, Yakubu Amidu and Hector Velasquez. A former member of the U.S. Marine Corps, Herring bounced back from his first defeat and stopped experienced contender Art Hovhannisyan in February.

A pro since 2014, Miller won his first nine pro fights as he used his speed and skills to out box opponents. Originally from Memphis but now living and training in Las Vegas, Miller has won four fights in a row, including three by stoppage. His last bout saw Miller fight to the eighth round for the first time in his career and impressively stop the then once-beaten Jesus Gutierrez in the final frame.
