Diego Pacheco stopped Immanuwel Aleem by TKO at 2:32 of the eleventh round on July 18, 2026, retaining his WBC Silver and WBO International super middleweight titles and improving to 26-0 (19 KOs). In his first fight under new trainer Buddy McGirt, Pacheco worked behind a sharp jab and a steady body attack, gradually breaking down the durable Aleem (22-5-3) before a sustained barrage forced the referee's stoppage. The performance — patient, structured, cumulative — keeps the 25-year-old on course for a world title shot and answered the question his previous outing had raised.
We asked one question in the preview: which Pacheco shows up? The answer arrived with a new accent — the version rebuilt by Buddy McGirt, and it was worth the wait of eleven rounds.
How the stoppage was built The finish reads as round eleven. It was actually purchased in rounds two through six: jab to organize the distance, then the body attack — steady, unglamorous, cumulative. Aleem, at 22-5-3 one of the division's honest measuring sticks, stayed durable exactly as long as his legs could pay the tax. When the sustained barrage came at 2:32 of the eleventh, the referee's stoppage was a formality the body work had scheduled hours earlier.
This is the oldest compounding strategy in boxing, and we keep writing it up because fighters keep skipping it: the body attack decides late rounds before they happen.
The McGirt effect A trainer change at 25-0 is a risk — new voice, new structure, first fight always a referendum. The referendum passed. McGirt's fingerprints were on every round: jab-first organization, defensive economy, no wasted violence. For a fighter whose previous outing had raised questions, this was the correct answer delivered in the correct dialect.
The career lesson Pacheco's night is a case study in changing your corner before you're forced to. The best time to rebuild structure is while you're still winning — when the change is a choice, not an emergency. It applies at every level of this sport, including yours: the moment your progress plateaus is the moment to audit the system, not double down on it. Run the honest audit before the loss does it for you.
Round eleven was the receipt. The purchase happened downstairs, hours earlier.
The rest of the weekend's ledger: Papot's upset in London and Eblen's interim title in Austin.
