A fit and focused Ruiz does. If he can't get up for a career high payday to defend multiple belts, what makes you think he trains for this?
Ruiz too fast hands for the Polish-American sausage who is tough but very limited skill wise and very easy to hit. Ruiz by UD.
Total one sided missmatch. Ruiz is superior technically, Ruiz has superior hand seeped (Kownacki has the slowest in thebtop 20) and Kownacki has no has no dfence whatsoever.
