Carbijal was a great fighter . He was 32 years old when he fought Arce, and in the lighter divisions that pretty damn old. I think Michael showed great poise in that fight , Michael never gave up and when the time was just right he put on the beat down. Great fight ,and a great win for Carbijal to retire WBO Light flyweight champion, pretty kick ass ! thought Arce fought brilliantly also and won the majority of the action packed rounds , made for a very entertaining fight
