Ultimate Fighting Championship (UFC) strawweight fighter Michelle Waterson demonstrating an armbar on amateur fighter Lim Zhen Teng yesterday at the TripleFit gym in Millenia Walk. The 31-year-old half-American, half-Thai, who is in town as part of UFC Fight Night Singapore on June 17, offered pointers to local fighters Lim and Charles Lew ahead of the International Mixed Martial Arts Federation Asian Open Championships later this month. The 12-bout event at the Singapore Indoor Stadium will be headlined by the clash between ex-UFC bantamweight champion Holly Holm and Brazilian Bethe Correia and marks UFC's second show in the Republic.
