We need to see Casimero, the version of him that dominates the bantamweight division. At least we should see Casimero scoring a knock down, to make the fans excited. But there is a possibility that this fight is going to distance.
Take note that this fight is the undercard, the main event is Hiroto Kyoguchi vs Vince Paras trilogy.
The promoter's website tb-promotion.com as well as their social media pages indicate that Casimero vs. Sanchez will be the main event. BoxRec might be showing the fights in a different order on the event page but that isn’t always the same order they will take place on fight night. It still says a lot that Casimero could plausibly be fighting on a small, obscure promotion’s undercards at this stage. He is not far off from that level if he were to lose.
It could be co-main event. However, I believed that the main card is the Hiroto Kyoguchi vs Vince Paras trilogy because of the impact of this fight. They will have to settle the score and so this is bigger than Casimero vs Sanchez fight.
But it's good that the Japanese promoter of Casimero was able to insert him whether main or co-main card here. And I will stay and watch that trilogy too, and hopefully Paras will win here.
