Ruiz makes it a longer fight, probably even outboxing a sluggish Tua by hanging on between shots, but eventually Tua's power tells and Ruiz goes down again to a KO loss. I don't think Ruiz would be dumb enough to leave his chin out there for a left hook again, but physically I think he'd struggle as he's simply not good enough at sticking 'n' moving to do what's needed against Tua.
A year or 2 ago, I'd have said that Ruiz takes this, as Tua is so inactive and seems to have lost much of his power/timing (and almost all of his speed/explosiveness). Now though, Tua's timing might just be returning, and Ruiz can't clinch with the same force as he used to. Tua UD/late KO
Right, because Peter has proven to be so talented in his last 4 fights right? Look, the fact is, the first Tua knock out was a fluke, a happenstance, a "lucky combination if you will. Tua came out fast and hard, and caught Ruiz off guard, a mistake Ruiz never made before, and hasn't made since, even when fighting guys twice his size, or twice his skill level. Ruiz will not get knoced out again, ever. Regardless if you think he cheated, faked anything, or brought a gun into the ring with him, that's all specualtion and opinion(I'm talking to you Zakman), the fact remains, he hasn't been knocked out aside fromt that one night.
