Gilberto Ramirez boxed better and moved more than usual Saturday night, and it served the Mexican contender well.

The sturdy southpaw also withstood Joe Smith Jr.’s power when Smith caught him during their 10-round cruiserweight fight at The Chelsea inside The Cosmopolitan of Las Vegas. Ramirez’s performance in his cruiserweight debut was more than enough to impress judges Tim Cheatham, David Sutherland and Steve Weisfeld – each of whom scored nine rounds for the former WBO super middleweight champion, 99-91 apiece.

Ramirez made a successful comeback from failing to make weight for a light heavyweight fight against Gabe Rosado that was canceled March 17 because Ramirez couldn’t even come close to meeting his contractual obligation. He also moved closer to a title shot in the cruiserweight division because he beat Smith in a WBA elimination match.

“I think I felt all the time I was ahead on the scorecards,” Ramirez told DAZN’s Chris Mannix in the ring. “But I never take any chance because he has heavy hands and he bring a lotta [power] to the ring.”

A thankful Ramirez credited Malik Scott, Deontay Wilder’s trainer, for helping him stick to his game plan Saturday night. Scott worked Ramirez’s corner because his longtime trainer, Julian Chua, couldn’t attend his fight with Smith.

Ramirez (45-1, 30 KOs) won in his first fight since he lost a one-sided, 12-round unanimous decision to WBA light heavyweight champion Dmitry Bivol (21-0, 11 KOs) last November 5 at Etihad Arena in Abu Dhabi. The hard-hitting Smith (28-5, 22 KOs), a former WBO light heavyweight champ from Mastic, New York, has lost back-to-back bouts to Ramirez and Russian knockout artist Artur Beterbiev (19-0, 19 KOs), who dropped Smith three times and stopped him in the second round of their 12-round, 175-pound title unification fight in June 2022 at Madison Square Garden’s Hulu Theater in New York.

Smith, 34, and Ramirez, 32, both made their debuts as legitimate cruiserweights in this fight. They both weighed in Friday a pound-plus below their contracted catch weight of 193 pounds, seven below the maximum for the cruiserweight division.

“It was a 20-pound difference and I feel great,” Ramirez said. “I feel a great performance, I feel healthy, I feel blessings. … Zurdo Ramirez is back.”

Smith drilled Ramirez with enough power punches to concern Ramirez, but he couldn’t put him down.

“You know, I gave it my best,” Smith said. “He boxed great tonight. I feel like I was a little heavy on my feet today and not letting my hands go, like I normally do. But yeah, I’m happy with my performance. I wish I was a little more busy, but I hurt him a couple of times. It woulda been nice to get him outta there, but I’m just happy I’m here, I’m good and, you know, congrats to him for boxing great.”

Smith seemingly needed a knockout in the 10th and final round to win.

Ramirez’s hard left to Smith’s body backed him into the ropes at the midway mark of the 10th round. Ramirez pressured Smith for much of those final three minutes and outlanded him.

Smith caught Ramirez with a hard right hand a few seconds before the final bell sounded.
