This is a good step up for Navarro who is only 2-0 but is facing a veteran journeyman who has only been stopped twice.
David Navarro was a good amateur who has recently turned pro and is expected to do good things as a professional. Diuhl Olguin is known for his toughness but not much else.
I expect David Navarro to win a six round decision due to being better fundamentally and still having a will to win while Olguin may have gone into a survival mindset after 16 losses.
