Gym Rat Call: Collazo is by far and away the more accomplished fighter here and this should be a straight forward defence for him

Record: 13 wins, 3 losses, 0 draws

Gym Rat: You know what's coming to you, pressure. You have to box your way around that southpaw stance. You have to get your foot outside his lead foot, get that straight right hand working and move

The Gym Rat's Prediction

Pick

Oscar Collazo

Method

Stoppage

Reasoning

Collazo has faced nothing but good opposition in recent fights, unifying the WBO and WBA titles, so maybe he does deserve an easy defence, something a little bit softer. With no disrespect intended to Haro, but with only 2 stoppages in 13 wins, I can’t see that he’s gonna have the tools to keep the champion off him. Collazo’s bodywork will wreak havoc, and I’m not sure how long the young Mexican/American is gonna be able to take the pressure. I think Collazo will win by early to mid-round stoppage.
