This is a step up in competition for the hard hitting Martinez who is currently rampaging his way through domestic Mexican fighters. Uriel Gonzalez is a bit of a gatekeeper around middleweight and generally gets stopped by the top prospects he faces.
Lester Martinez was a standout amateur and appears to carry power as a pro. He’s technically good with an aggressive style which has led him too six knockouts in six fights.
Uriel Gonzalez hasn’t shown much durability when facing top prospects and I don’t expect it to be any different here. He’s a solid domestic Mexican middleweight but is just outclassed in this match up.

I think Lester Martinez will win by knockout within three rounds due to his power and technical skills which hes got from his extensive amateur background.
