Edwin Valentin is a good prospect who is 9-0 but has been inactive since 2019. Hector Marengo is a journeyman who hasn’t fought since 2018.
I personally can’t see this fight going beyond three rounds as I fully expect Edwin Valentin to win by knockout. Hector Marengo hasn’t won since 2014 and is coming out of retirement for this fight so I don’t think he’ll be very motivated to win.
