Amnat Ruenroeng to defend IBF title against John Riel Casimero in rematch

IBF flyweight titleholder Amnat Ruenroeng of Thailand will be be back in action on May 25, as he'll head to Beijing to take on John Riel Casimero of the Philippines, a fight that will be part of the IBF convention.

The 36-year-old Ruenroeng (17-0, 5 KO) won the vacant IBF title in 2014, beating Rocky Fuentes in Thailand, and then made successful defenses against Kazuto Ioka and McWilliams Arroyo that same year. In March 2015, he went to Macau and beat Shiming Zou.

The fight with Casimero (21-3, 13 KO) will be a rematch of a bout from last June, which Ruenroeng won by decision in Bangkok, on scores of 116-110, 115-110, and 113-112, certainly close enough that the rematch makes sense.

Casimero, 26, hasn't fought since then, but is a former IBF champion at 108 pounds. His other two losses came in 2010 against Ramon Garcia and in 2011 against Moruti Mthalane.

The Ruenroeng-Casimero fight is the first one set for the convention card, and will be the main event of the show.
