Dan Rafael

Over the past 18 months, the gap has closed between Martinez and Chavez -- but not enough, as far as I am concerned. It will be a good fight, but I like Martinez in a late stoppage.

Kieran Mulvaney

This is tough to call because Martinez has struggled a little with pressure fighters, but I think Sergio's speed and skill prevail over Junior's size and strength, earning him a close decision win.

Diego Morilla

Martinez's experience and maturity will help him dominate the first three-quarters of the fight, and Chavez's resurgence toward the end will be futile. Martinez on points.
