2000-02-05 Pichit Chor Siriwat w pts 12 Sang-Ik Yang, Mall Department Store, Bangkok, Thailand - WBA. Referee: Derek Milham. Scorecards: 120-110, 118-111, 115-113. Displaying superior speed and ring-craft to dominate his fellow southpaw, Chor Siriwat (108) continuously outmanoeuvred the taller Yang (108), who was unable to get into range and often flailed away hopelessly. Despite being out of the ring for almost a year, Chor Siriwat had too much of everything for the challenger to overcome.
After Chor Siriwat forfeited the WBA version of the title in July 2000 for failing to meet Rosendo Alvarez within the given time frame due to illness, the latter was hastily matched against Beibis Mendoza to contest the vacancy.
