What About the Right Hand?
Ruiz injured his right hand in his last fight. He had surgery on it. We do not know if he fully trusts it. His quick combinations are his best weapon. He needs his right hand to be effective. He cannot just use his left hand. Knyba will test that hand early. Ruiz must commit to his punches. He must show no fear. We will see how it holds up.

Ruiz Jr. vs. Knyba: Fight Analysis
This is a hard fight to pick. Ruiz has not fought much. His hand is also a question mark. Knyba is huge and will use his jab. I expect Ruiz to be slow early. He will have to figure out the distance. But Ruiz has amazing hand speed. He is also a smart fighter. He will get inside and land combinations. His experience will be key. If he is in good shape, he will win. Knyba will be tough and last the whole fight. I think Ruiz will win by a clear decision.
