Diego Pacheco (167.8) vs. Immanuwel Aleem (167) — Main Event, WBC Silver / WBO International Super Middleweight Titles
Co-Main Event: Cruz vs. Montoya
Two-time Olympic gold medalist Andy Cruz (6-1, 3 KOs) headlines the undercard against Mexican veteran Abraham Montoya (24-7-1, 14 KOs) with the WBC USA Silver lightweight title on the line. Cruz was originally lined up against Albert Bell in an IBF title eliminator before Bell jumped at a short-notice shot against WBO champion Abdullah Mason. Montoya stepped in on late notice off a split decision win over Antonio Perez in April.
This one is really about Cruz proving something to himself. The Cuban southpaw’s amateur pedigree had him ticketed for a smooth run through the pro ranks, but Raymond Muratalla exposed real cracks in January, a disputed majority decision loss that snapped his unbeaten start and showed he can be forced to fight at a pace he doesn’t control. Montoya isn’t Muratalla’s level, but he’s a pressure fighter who has never been stopped in 32 pro fights, and how Cruz handles that style will say a lot about the adjustments he’s made. Doc’s staff likes Cruz to get back in the win column, but this is a measuring-stick fight more than a formality.
Tale of the Tape: Pacheco vs. Aleem

| Age | 25 | 32 |

Film Study
Pacheco is a size anomaly at 168 pounds. At 6’4″ with a 79-inch reach, he is giving away nothing and taking seven inches of height and nine inches of reach off most of the division. He fights behind that length, working a heavy jab to set up his power, and the résumé backs up the undefeated record. His last five wins have come against savvy, experienced names in Shawn McCalman, Maciej Sulecki, Steven Nelson, Trevor McCumby, and Kevin Lele Sadjo, not soft touches. He’s ranked inside the top four of three different sanctioning bodies at 25 years old, trained by Hall of Fame corner man Buddy McGirt, and still has room to get better.
Aleem has been a professional since 2012 and has made a career out of testing prospects on the way up. That experience cuts both ways. He has won just three of his last five, with a loss to Lester Martinez and a draw against Winfred Harris Jr. mixed in among wins over Malcolm Jones, Vitalii Gubkin, and Demond Nicholson. Here’s my concern watching the tape: fourteen years as a professional is a lot of mileage to carry into a ring against a bigger, younger puncher who finishes at a 72 percent clip. Chin durability doesn’t hold steady forever, and Aleem is about to find out how much he has left against a fighter with a real height and reach advantage.
Betting Odds
Pacheco -2000 to -3300 / Aleem +900 to +1300, depending on the book.
Cruz -3333 / Montoya +1200.

Prediction
Doc’s staff has this one going the way the odds suggest. Pacheco’s jab and reach should let him control range from the opening bell, and once he starts finding a home for the right hand, Aleem’s defense has shown enough cracks over the years to get exploited. Look for Pacheco to wear him down behind the jab through the midrounds and close the show late, somewhere around round seven or eight, before the final bell. A statement win here puts him squarely in line for one of the division’s beltholders next.
