This should be an easy tune up fight for Yvan Mendy who has mixed it at world level versus numerous opponents. Antin has become a journeyman in the last two years and in his two fights outside of Argentina hes lost both.
Yvan Mendy is decent technically and while hes not a world class puncher he has enough to keep people wary. He has a few good wins over Luke Campbell and Francisco Patera and in 52 fights has never been stopped.
I think Yvan Mendy should be able to use his superior boxing skills and experience to stop Antin in the seventh or eighth round.
