Alexandre Pantoja  believed a win over  Matt Manzanares would get him a call from the UFC. Now time will tell. Pantoja had some dicey moments in the first round, but in the second he went to work, eventually choking the champion unconscious at 2:38 of the second round to take RFA’s flyweight title. The 125-pound championship bout was the main event of RFA 18, which took place at Albuquerque Convention Center in Albuquerque, N.M.
