The referee for the bout will be Japan's Kazunobu Asao, who has got world title experience having done fights like Naoko Fujioka Vs Naoko Yamaguchi and Poonsawat Kratingdaneggym Vs Ryol Li Lee. Notably this appears to be his first assignment in Thailand in more than 20 years, going back to when Asao was the third man in the ring for a bout between Khaosai Galaxy and Je-Suk Park back in 1991.
The judges will be Levi Martinez, Octavio Rodriguez and Ferlin Marsh.
Martinez is an American who has been busy this year having judged a number of bouts in El Salvador. Notably he's returning to Asia after having been in Japan for two fights back in December, though he wasn't needed in either of those bouts as Kosei Tanaka stopped Vic Saludar in 6 rounds and Naoya Inoue blew away Warlito Parrenas in 2 rounds. He's a very experienced judge and although he had some poor cards, including an awful card for the McJoe Arroyo Vs Arthur Villanueva bout, where he had Arroyo winning 98-91, he is generally pretty solid.
Rodriguez is a Panamanian judge who, again, has been around and is experienced. At the end of last year he was in Russia though has been to Argenian, El Salvador, Haiti, Mexico, Peru, Thailand, Germany, Dominican Republic, South Africa and Monaco. Interestingly he did the first bout between these two men, back in 2014, and had the bout scored 115-113 to Buitrago, like both of the other judges.
Marsh is from New Zealand and, according to boxrec at least, is a somewhat new judge with boxrec having only 18 bouts to his name, though the first of those was in 2001. Those bouts include contests in China, Japan, Korea and Monaco. His most notable bouts include Hisashi Amagasa's bout with Guillermo Rigondeaux, which he had 107-99 after 11 rounds, Takashi Uchiyama's contest with Jomthong Chuwatana, which he had 10-9 after one round, and Randy Petalcorin's win over Walter Tello, which he had 59-55, though notably they all ended in stoppage.
