Munguia vs O’Sullivan results: Tristan Kalkreuth, Travell Mazion, George Rincon score quick stoppages on prelims

Tristan Kalkreuth KO-1 Blake LaCaze

Kalkreuth is a teenage cruiserweight, 18 and fighting in the 180s, with the idea maybe that he can lean out and do 175, which might be fun at 6’4”, but it’s unlikely by the time he’s ready to fight anyone serious that he’d still be making 175 given that he’s young and his body will still be growing, developing the vaunted MAN STRENGTH!!! and all, at least for a while.

Our live coverage for Munguia vs O’Sullivan continues here!

Kalkreuth goes to 4-0 (3 KO) with this win, a quick wipeout over 6’8” LaCaze (4-8-2, 2 KO), a 24-year-old club fighter from Louisiana who went down twice in short order. Because of LaCaze’s dimensions both knockdowns were sort of cartoonish, which I don’t mean to disrespect the fact that Kalkreuth legitimately hit him and hit him hard, just that really tall people fall weird. Kalkreuth will be on loads of these prelims for a while now, so we’ll get to know him as he moves along, see if he’s the real deal or not.

Travell Mazion KO-1 Fernando Castaneda

Mazion (17-0, 13 KO) is a 24-year-old junior middleweight from Austin, a tall guy at 6’2” with a 75-inch reach, an interesting prospect we’ve now seen a few times on DAZN cards. Mazion was promising a “jab party” in this fight, and with good reason; Castaneda (26-14-1, 17 KO) has been around the block, knows his way around the ring and all that. Not terribly durable, but usually hangs around a bit.

Instead, Mazion absolutely demolished him with a left hook to the body, and Castaneda was down instantly and in clear, miserable pain. The 31-year-old Mexican journeyman got to his feet, but only for a moment, as he crumpled back to the canvas and the fight was over in 58 seconds. It was a hell of a body shot, clearly.

“I really thought he was gonna give me a little bit,” Mazion said. “I didn’t expect that body shot. But what happens happens in the ring. Whatever comes up. I landed it, so that’s what got it.”

Mazion says he’s looking to get into the title mix, and had a specific opponent in mind.

“Whoever has a belt, I’m coming for,” he said. “Patrick (Teixeira) from Brazil, who has the WBO belt, I agreed to fight him a long time ago, and he turned me down.”

George Rincon TKO-1 Diego Perez

Rincon (10-0, 7 KO) is a 27-year-old junior welterweight from Texas, a little old for the level he’s still fighting at, honestly, but has some skills and power. He showed that power here, dropping Perez (13-10-1, 11 KO) three times in the opening round, getting the stoppage at 2:53. But it also has to be said that Perez, a 33-year-old Nicaraguan, has had about the same result in his previous bouts outside of his home country, and he wasn’t exactly untouchable at home, either.

We had a scary scene post-fight where Rincon passed out in his corner and had a seizure. He didn’t take any punishment in the fight — remember, we mean Rincon, the winner, not Perez, that’s not a typo — but he came out of it and seemed fully composed. No idea if he has a preexisting medical condition or something like that, but Rincon left the ring under his own power and visually appeared to be fine.
