Patrick Rivera

Rivera pairs a documented three-fight win streak with a 13-4-0 record — roughly double Darby's professional mileage.

Rivera holds the deeper record at 13-4-0 and is 3-0 across his logged fights, beating Rey Trujillo in March 2026, Cole Presley in November 2025 and Justice Lamparez in July 2025. Darby is 7-1-0 and also won all three of his bouts on file (Thiago Habib, Robert Alexandru Constantin, Tato Primera), but he has fought roughly half as many total professional fights. Both are experienced and both are equally current (Rivera last out March 2026, Darby February 2026), so with form even, Rivera's greater accumulated experience is the tiebreaker. No finish or grappling data is available for either man, so this is a thin edge.
