Tomoki Kameda will defend his WBO bantamweight title against Pungluang Sor Singyu on the Showtime-televised undercard portion of the July 12 main event between junior middleweights Canelo Alvarez and Erislandy Lara, the network announced on Thursday.
Kameda, who turns 23 on the night of the fight, will face his most experienced opposition yet in Pungluang, 26, who has produced three wins in a row since losing the WBO title to Paulus Ambunda in 2013. Kameda took the belt by a wide unanimous decision in Ambunda's first title defense.
Both Kameda (29-0, 18 knockouts) and Pungluang (46-2, 31 KOs) will be making their U.S. debuts at the MGM in Las Vegas.
In other bouts on the pay-per-view portion of Alvarez-Lara, three-division titlist Abner Mares will face veteran Jonathan Oquendo in Mares' first fight under trainer Virgil Hunter, junior welterweight contender Johan Perez will battle former title challenger Mauricio Herrera and former two-divsion titleholder Juan Manuel Lopez will clash with Francisco Vargas in a 130-pound bout.
Kameda and his two brothers, Koki, 27, and Daiki, 25, are among the most famous fighters in the history of Japanese boxing.
All three siblings recently held titles at the same time. Tomoki held the WBO bantamweight belt, and Koki was the WBA 118-pound titleholder until he vacated in December in order to move down to flyweight.
Daiki was the IBF Junior Bantamweight Champion until he lost by decision last December.
