Gilberto "Zurdo" Ramirez is getting geared up his next return on June 30 at the Chesapeake Energy Arena in Oklahoma City.

In the main event of that card, Ramirez (37-0, 25 KOs) will defend the WBO super middleweight title against unbeaten Colombian challenger Alexis Angulo (23-0, 20 KOs), 

Ramirez-Angulo awill be televised live on ESPN and ESPN Deportes at 9 p.m. ET.

Angulo is regarded as a dangerous puncher, but he's never faced anyone on the level of Ramirez.

The Mexican fighter is not going to take him lightly.

"We've seen a couple of tapes. He's a big puncher. He has a good record, and I have been preparing very hard for him. I've been doing a lot of sparring with different guys, and I'm ready to put on a great performance for Oklahoma City and the people watching on ESPN," Ramirez said.

"He'a dangerous fighter because we don't know what he brings. Like I said, I prepared really well for this fight. We don't know what kind of strategy he brings to the ring, so we're preparing with different styles."

Beyond Angulo, Ramirez is hoping to fight one of the other champions in the weight class - like WBA world champion George Groves, IBF champion James DeGale or WBC champion David Benavidez.

Groves is involved in the World Boxing Super Series tournament and won't be available. DeGale is recovering from several bad cuts that were suffered in his last bout against Caleb Truax, so he's on the shelf until the end of the year. And Benavidez is scheduled to return in September in a mandatory defense against Anthony Dirrell.

"I am looking for unification fights. That's what I want. But first things first. We have a tough fight with Angulo, and after that, we are looking at any of those fighters. Let's do it. Let's make it happen," Ramirez said,
