RJ Harris enters Saturday’s UFC Vegas 122 heavyweight matchup against Allen Frye Jr. as the clear betting favorite, with BetMGM listing Harris at -350 and Frye Jr. at +275. The line reflects the different paths both men took into this fight, with Harris arriving unbeaten and Allen Frye Jr. trying to rebound from a defeat in his UFC debut.
The fight takes place inside the Meta APEX in Las Vegas, and it is one that gives bettors and fans a simple but important question: can Allen Frye Jr. bounce back quickly enough to test an opponent who looked sharp in his first promotional appearance?
Harris brings momentum into Las Vegas
Last year, the UFC signed Allen Frye Jr., but his first outing did not go to plan. In December, at UFC Vegas 112, he suffered a decision defeat against Guilherme Pat, leaving him needing a response in his next assignment.
RJ Harris, by contrast, has carried momentum into this matchup. The UFC signed him earlier this year, and in July he made his promotional debut by stopping Alvin Hines at UFC OKC. That result helped establish him as a fighter to watch and explains why he is favored here.
Why the odds point toward Harris
The betting line is not only about the win-loss records. It also reflects the way the fight projects stylistically, with Anatoly Pimentel backing Harris to win by TKO or KO and describing him as the better overall striker.
That is the key point in a heavyweight fight like this. If Harris can establish himself early and keep the range where his striking matters most, he will back up the market view. If Allen Frye Jr. can drag the contest into an uncomfortable fight and slow the rhythm, the underdog price starts to look more interesting.
For now, though, the momentum sits with Harris. He is undefeated, he has already shown he can finish inside the UFC, and the odds suggest bettors expect that form to continue on Saturday.
Allen Frye Jr. still has a chance to change the conversation, but this is a matchup where the pressure sits firmly on the man trying to recover from his debut setback. Harris has the cleaner recent record, the stronger promotional start and the kind of finishing profile that the market has rewarded.
