Beterbiev is too strong. His straight right hand is a southpaw killer. Unlike a lot of orthodox fighters who are reluctant to open up vs southpaws, Beterbiev has ample experience fighting them. He had 3 fights vs Usyk in the amateurs and despite going 1-2 in those fights, he always managed to hurt Usyk with his right hand. Beterbiev's right hand will make Zurdo reluctant to open up. If he does open up, he will get overpowered. If Zurdo boxes defensively , turns Beterbiev with his angles and footwork while occasionally opening up, he will last the distance and perhaps win 4-5 rounds and make it a close fight. On the other hand, if Zurdo opens up as much as he did yesterday, he will get overpowered and stopped.
CBS is a solid fighter but he isn't anywhere near Beterbiev's level power and skill wise. Beterbiev by late stoppage against Zurdo. Bivol comfortably beat Zurdo on points.
Beterbiev.. but Ramirez is a very good fighter , which just shows how good Bivol is... 47 fights in & hes only lost to Bivol.. that win and the manner of it is quite underrated.
