It's two weeks before the match between Navarrete Vs Berinchyk this is Berinchyk US debut I'm sure he going all out to capture the US market.
By the way, the undercard is also very interesting it is a battle of undefeated fighters, these may not be popular names in boxing but they soon become popular, if you notice on all the cards only Navarette has a loss in all the fighters but make no mistake about it, he is a great fighter and holder of the record of the most punches thrown in one fight.
Giovanni Santillan might also be a must watch in this undercard, as he is the co-main event here.
He is rank number 6 by WBC and number 4 by WBC and number 1 by IBF at 147 lbs, so his name could be in the top contender in the next following year, although if I'm not mistaken, he has been in the boxing for several years now but hasn't been given the chance to crack for the belt.
