Last fight was against Darley Perez and didn't look impressive at all... Gamboa is turning 33 next year and no upcoming big fights yet.
Move back down to 126(where he belongs) and fight Garcia or Donaire for BIG MONEY...then cashout and retire. I understand that 50 has big plans for Gamboa but , I just don't see him being competitive with any of the current beltholders at 135. He's too short for that division and he can't infight.
