What time is John Riel Casimero's fight tonight? Live stream info, start time, how to watch Casimero vs. Guillermo Rigondeaux

There's something about John Riel Casimero that irks Guillermo Rigondeaux outside of the ring.

Rigondeaux plans to flip the script inside of the ring Saturday night, when he challenges for Casimero's WBO bantamweight title in Carson, Calif.

The 40-year-old Rigondeaux vows to throw Casimero for a loop with his fighting style.

"That's where he's going to get confused," the two-division world champion told DAZN News. "He dreams of me, the trainer, the manager dreams of me. Every time they talk they have to mention Rigondeaux. They dream about me. They are going to go crazy.

Rigondeaux added: "For everything that every fighter brings ... what happens there is they get frustrated. What I do there is that I hesitate and the more uncomfortable they get, the more I enjoy being in the ring and I do everything I want to do."

Will Rigondeaux's words come true or will Casimero get the better of the celebrated Cuban boxer?
