A kid who once fought on a blanket is now 15–0 with 11 knockouts, and he’s aiming his sights at the top of 115–118. We sit down with a New Mexico fan favorite Matt Griego AKA Diamond Boy who blends power and patience, talks candidly about a derailed fight week that sent him spiraling, and explains how the gym became his medicine. From first-round fireworks on his pro debut to a steady refusal to accept short-notice traps, he breaks down what real preparation looks like and why the right camp changes everything.
We dig into the business side of boxing—managers, matchmaking, and the quiet calculus promoters use to protect prospects. He shares why he keeps getting last-minute calls for the same opponent and how staying near fight weight keeps him ready without burning him out. The call-out is clear: John “Scrappy” Ramirez of Golden Boy. Respect for the fighter, zero doubt about the matchup, and a simple request for a full camp to make the best fight possible.
Mentorship matters here too. Training with the late Johnny Tapia added rhythm, shifting, and heart to his style, along with a personal story of generosity that still fuels him. Outside the ring, the barber chair became a second platform—steady income, local roots, and a community that shows up loud. If you’re curious about how a contender navigates the chaos of boxing while building a life that lasts, this conversation brings grit, insight, and a path forward.
