Amateur Fireworks Incoming: JoJo "Smoke" Griffin vs. R.J. Mendoza at RUF 69

PHOENIX, AZ — June 22, 2026 — Some of the best action on any fight card never reaches the main event, and the amateur catchweight clash between JoJo "Smoke" Griffin and R.J. "The Menace" Mendoza at RUF 69 is exactly that kind of fight. Two hungry competitors, one cage, one winner, and zero reason for either man to take a backward step. When the cage door closes at the Celebrity Theatre on July 11, 2026, this is the bout that reminds everyone why amateur MMA in Arizona is a breeding ground for future stars.

The Prospect on the Rise: JoJo Griffin

JoJo Griffin walks in as the more proven of the two, carrying a 3-1 amateur record with a No Contest also on the ledger. That winning mark is no accident. Fighting out of Red Hawk Academy in Phoenix, Griffin has already logged real cage time on the RUF stage, including an appearance back at RUF 61 against Daniil Zheliaskov, and that experience under the bright lights of the Celebrity Theatre matters. He has felt the nerves of fight week, walked to the cage in front of a live Phoenix crowd, and come out the other side with his hand raised more often than not.

For an amateur, momentum and confidence are everything, and Griffin has both. A fighter sitting at three wins is a fighter who has learned how to close shows and impose his game when it counts. He is the kind of competitor RUF likes to build around: a local talent stacking wins, sharpening his tools, and inching closer to a potential pro debut with every appearance. Expect Griffin to fight like a man who believes the spotlight belongs to him.

The challenge for Griffin is the target on his back. As the favorite on paper, he has the most to lose. A rising prospect is only as good as his last performance, and Mendoza is exactly the type of dangerous, nothing-to-lose opponent who can derail a hot streak if Griffin looks past him for even a moment.

The Menace with Nothing to Lose: R.J. Mendoza

R.J. "The Menace" Mendoza hails from Safford, Arizona, and he arrives with a 1-2 amateur record that tells only part of the story. Records can be deceiving in the amateur ranks, where matchmaking is brutal and every fighter is still figuring out their identity. What matters is that Mendoza keeps signing the contract and keeps stepping into the cage. He has stayed active on the regional scene, with bookings across RUF and other Southwest promotions, and that willingness to fight anyone is exactly what earns a nickname like "The Menace."

Mendoza is the underdog here, and underdogs in amateur MMA are the most dangerous fighters in the building. He has nothing to protect and everything to gain. A win over a 3-1 prospect like Griffin would be the signature result of his young career, the kind of upset that flips a record around and announces a fighter has arrived. Men in that position tend to fight with desperation and freedom at the same time, and that combination produces finishes.

The path for Mendoza is pressure and pace. If he can drag Griffin into a phone-booth war, force exchanges, and refuse to let the favorite settle into a rhythm, the experience gap shrinks fast. Amateur fights are short, and chaos favors the man who is comfortable in it.

Tale of the Tape

Card and matchups subject to change.

Where the Fight Is Won and Lost

This is a classic prospect-versus-spoiler matchup, and the opening exchanges will set the tone. Griffin wants to fight a measured, technical fight that lets his experience and confidence carry him to a clean decision or a late finish. He has the cage time to stay calm when the action heats up. Mendoza wants the opposite: a fast, messy, high-volume scrap where heart and grit close the gap that the records suggest.

The pace is the key variable. If Griffin controls distance and dictates where the fight takes place, his polish should show through over three rounds. If Mendoza turns it into a brawl from the opening bell, all bets are off, because amateur fighters at this weight throw with bad intentions and the margin between winning and losing can be a single big moment. Neither man is here to play it safe, and that is precisely why this fight made the card.

Don't Miss It

Amateur MMA is where future champions are forged, and JoJo Griffin versus R.J. Mendoza is the kind of fight that defines the level. A proven prospect protecting his momentum. A determined menace looking to crash the party. When the cage door closes, expect action from the opening bell and a finish that neither man will let slip away.
