Many think the WBA junior welterweight title fight between Rolando Romero and Isaac Cruz could steal the show on Saturday night.

They meet at T-Mobile Arena in Las Vegas on a bill topped by the unified junior middleweight title bout featuring Tim Tszyu against Sebastian Fundora, and at today’s public workouts at the MGM Grand, Romero promised that he and “Pitbull” Cruz would deliver the fight of the night.

Both competitors did some shadowboxing for the fans and the cameras as they completed their preparations, and Cruz said he was ready to go.

“It’s been great,” he said of the build-up. “I couldn’t have a better team to work with. We’ve done an outstanding job of getting ready, and I’m in tip-top shape for this fight.

“You could say perhaps this has been the best training camp of my career, and that’s all due to the work I put in with my dad and the whole staff that has been here supporting me all the way.”

Mexico’s Cruz (25-2-1, 17 KOs) is a sawed-off fighter hoping to bring hell to Romero’s door. Both fighters have lost to Gervonta Davis, but “Tank” had his hands full with Cruz, winning a narrow decision. Last July, Cruz defeated Giovanni Cabrera for a split decision in a fight that failed to catch fire. But the promise of violence hangs over Romero-Cruz on Saturday.

“It’s a big second chance [at a world title] and a very important second chance,” said Cruz, who is moving up from lightweight for the assignment. “I came to give the people what they want – a great fight – and I want to come out on top.”

Asked about Romero’s power, Cruz added: “Don’t worry, I’m not going to come out with my hands down. I will be ready for whatever he wants to do. Pressure means nothing to me. I work based on the fundamentals that I have ever since I started training camp. I came here to be world champion, period. I’m going to be a world champion on Saturday night, and the true winners will be the fans that are here.”

Romero was typically jovial and talked about how he had eaten some blueberry cheesecake earlier in the day, a sign of how comfortable he now is at 140.

“I was killing myself to make 135 real bad, and it’s been like that for a good many [fights],” Romero said, before talking about moving up in weight yet again. “I want to go to 147 – that’s where all the fun is. I will go to 147, I’ll stay at 140, I’ll do whatever. You know I ain’t ducking anybody.”

He called Cruz “a small guy” and then discussed the possibility of his opponent coming in and starting fast, setting a ferocious pace. “Rolly,” at ease with his own punching power (13 KOs in 15 wins; his lone loss was to Davis via stoppage), said: “Everyone can think about that until they get punched in the face by me, right. Everyone slows down the second they get punched by me.”

Romero’s focus then became Cruz’s aggression, and how he planned to use that against his challenger.

“This is the first motherfucker I don’t got to go and chase,” Rolly quipped. “It’s going to be a lot of fun. 

“I ain’t got to set traps; he sets himself up for them. What do you think he’s going to do? Do you think he’s going to go out there and try and box, thinking he’s Floyd [Mayweather] or something? Or is he going to come in headfirst like he always does? 

“I don’t got to set traps. He’s already set up.”
