#IsaacCruz needed 53 seconds. Two right uppercuts, two knockdowns, a two-time title challenger demolished. This is Pitbull off the chain, and once he's unleashed, he locks on and doesn't let go. His words after: "Mike Tyson from Mexico was born tonight." He faces Nestor Bravo Saturday night. 🥊 #PitbullBravo | LIVE on @daznboxing #Boxeo #IsaacPitbullCruz #PBC
