This should be a decent fight between two talented fighters near the start of their careers. Martinez was a good amateur who’s made a perfect start to his pro career but hasn’t faced a strong level of opposition yet. Santana had an amateur background himself back in Cuba but not on the level of Martinez. Santana has faced domestic opposition in Russia and Mexico and while he’s won most of his fights he hasn’t exactly shown hes a clear level above his opponents for the most part.
I think Lester Martinez will put the pressure on from round one and will get a knockout in round three or four due to being the bigger man with the deeper amateur pedigree and technical skills, Martinez also has a power advantage.
