Six months after his debatable draw with Christian Mbilli, Martinez got it done against Immanuwel Aleem on Saturday night at Orange Show Events Center in San Bernardino, California. Martinez won a lopsided unanimous decision and the WBC interim super middleweight title.

The three judges scoring it from ringside had it 120-108, 119-109 and 118-110 for Martinez (20-0-1, 16 KOs), ranked No. 4 by The Ring and No. 2 by the WBC at 168 pounds. Thanks to his victory, Martinez became the first fighter from Guatemala to win at least some portion of a world title.

Aleem, who’s ranked No. 8 by the WBC, grabbed wins in four of his previous five fights, but he couldn’t get it going. The 32-year-old American took the center of the ring in the first round while flicking out a strong jab. Martinez, though, was calm and cool as he deflected those shots off his gloves and fired off with a couple shots of his own.

In the second, Martinez remained relaxed. He landed a handful of uppercuts and slick right hands. Aleem seemed puzzled and unable to get out of the way. The third and fourth rounds were much the same, but in the fifth, Martinez turned up the aggression.

During that round, the Guatemalan champion pushed his man back and attacked the body. Aleem didn’t seem to be in over his head, but his offensive attack was tenuous.

After firing up their fighter in the seventh, Aleem did his best to push the pace. Martinez languished against the ropes, but he didn’t appear to be in much trouble.

Aleem (22-4-3, 14 KOs) let his hands go in the 10th. That’s where things got dicey, as Martinez stumbled against the ropes thanks to a strong left hand. Ultimately, Aleem’s lack of offensive creativity showed, as Martinez used timely head movement in the final two rounds and a concentrated attack to the body and head to end things strongly.

Martinez now holds the same title that eluded him last year. The 30-year-old contender fought Mbilli to a controversial split draw on the undercard of Terence Crawford’s win over Canelo Alvarez on September 13 at Allegiant Stadium in Las Vegas.

Following that outcome, the WBC ordered an immediate rematch. Mbilli began weighing his options, though, and their rematch never took place.

Martinez inched closer Saturday night to a rematch with Mbilli, who was elevated to full WBC titleholder on January 27. Crawford was stripped of the WBC’s super middleweight title before he announced his retirement in mid-December because he didn’t pay his sanctioning fee for his fight versus Alvarez.

Placed just one spot above Martinez in The Ring’s super middleweight rankings, Mbilli (29-0-1, 24 KOs) is hoping to land his own fight with Alvarez. The Mexican star had arthroscopic surgery on his left elbow following his loss to Crawford, but he’ll return September 12 in Riyadh, Saudi Arabia, against an opponent to be determined.

When Martinez was asked what he wants to do next, he didn’t name anyone specific, but he made it clear that he isn’t ducking anyone.

“I’m ready,” Martínez said during his post-fight interview. “I’m ready to fight and do the best fights for you. We’re ready to fight the best.”
