The UFC is back at the UFC Apex in Las Vegas for the first time since May for Saturday’s UFC Vegas 108 fight card. The main event of this week’s UFC offering came together on short notice. In that matchup, Hyun Sung Park steps in for the injured Amir Albazi against top-10-ranked UFC contender Tatsuro Taira. Below, we look at the betting odds, betting line movement, potential prop bets, predictions, and picks for the UFC Vegas 108 main card.

UFC Vegas 108 Fight Card Main Event: Betting Odds, Line Movement And Predictions – Tatsuro Taira Vs. Hyun Sung Park

Tatsuro Taira (16-1) rose through the UFC flyweight ranks fairly quickly. He joined the UFC in May 2022 with a record of 10-0, and after winning the Shooto flyweight title.

Taira opened his UFC career with a unanimous decision win over Carlos Candelario in May 2022. He followed that with back-to-back submission wins in contests where he earned “Performance of the Night” bonuses, defeating C.J. Vergara and Jesús Santos Aguilar.

Wins over Edgar Chairez and Carlos Hernandez in 2023 followed.

In June, Taira got the first true test of his UFC career when he faced Alex Perez in a main event on a UFC Fight Night card at the Apex. At the time, Taira was the No. 13 ranked fighter in the UFC’s flyweight division, and Perez, who had fought Deiveson Figueiredo for the UFC 125-pound title in 2020, was ranked No. 5.

The fight ended when Taira took the back of his opponent in the center of the Octagon and forced him to the mat, putting enormous pressure on Perez’s knee and causing an injury that brought the fight to a halt in the second stanza. From all appearances, and judging from his comments after the victory, the move that finished the contest was a designed technique.

That win put Taira at No. 5 in the UFC rankings, earning him a shot at former UFC flyweight title challenger Brandon Royval, who entered the October 2024 contest as the No. 1 ranked in the UFC’s 125-pound division.

Royval and Taira put on a “Fight of the Night” bonus-winning scrap, but the more experienced Royval took home the split-decision win, handing Taira the first loss of his professional career.

The 25-year-old Taira is currently the No. 6 ranked UFC flyweight.

Hyun Sung Park (10-0) won Road to UFC in early 2023 with a knockout of Seung Guk Choi. He followed that with a knockout of Shannon Ross in late 2023. Park did not compete in 2024 having had fights against Andre Lima and Nyamjargal Tumendemberel cancelled. He returned to the Octagon in March, scoring a first-round submission win over Carlos Hernandez at UFC Vegas 106.

I wrote of the 29-year-old at the time, “HyunSung Park looked excellent at UFC Vegas 106, moving to 3-0 in the UFC’s flyweight division. Park used effective striking to hurt Carlos Hernandez against the fence. That striking made Hernandez move to the clinch, but Park showed his overall MMA ability in scoring a takedown, which led to a back take and a rear naked choke sub at 2:26 of Round 1. The 29-year-old Park looks ready for a test in his next outing as he has picked up three finishes in three UFC outings.”

He gets that test in a big way and on short notice on Saturday night.

Park has only gone the distance once in his MMA career.

When the betting odds opened for this matchup, Taira was a -350 betting favorite over Park, who came in as the +275 betting underdog.

Bettors are taking the underdog in the hopes of an upset. Park has earned 74 percent of the bets, while picking up 75 percent of the handle.

The good news heading into this fight is that Park is not coming into UFC Vegas 108 fully unprepared. He was booked opposite Steve Erceg for next week’s UFC Vegas 109 card, so he will at least face Taira with most of a fight camp behind him. However, that fight was scheduled for three rounds, while this contest is a five-round affair.

Taira is a good striker, he is better on the mat. However, he is aware how fights are scored, so he’ll engage in striking before moving to his grappling. Park, on the other hand looks to grapple first.

Taira is the more well-rounded fighter in this contest and that will allow him to carry the day. The pick is for Taira to win via stoppage. I see him scoring a knockdown against Park, but I’m unsure if the finish will be more strikes or if Taira follows things to the ground to get the sub. Considering Taira’s grappling skills, go with the submission.

Unlike the main event, the favorite in this matchup has the bulk of the bets (71 percent) and handle (90 percent.)

The betting pick is Rebecki to score a dominant decision win.

UFC Vegas 108 Fight Card: Betting Odds, Line Movement And Predictions – Elves Brener Vs. Esteban Ribovics

A lightweight matchup between Elves Brener (16-5) and Esteban Ribovics (14-2). Ribovics opened as the -300 favorite over the +240 Brener. The line has gotten a little closer on this one, but not by much. Today, Ribovics is listed at -250, while Brener checks in at +200.

The bets are split 50-50 on this one, but most of the money is coming in on Brener at 82 percent.

The pick is Ribovics to win via decision.

UFC Vegas 108 Fight Card: Betting Odds, Line Movement And Predictions – Karol Rosa Vs. Nora Cornolle

In this contest, we have a matchup of ranked women’s bantamweight competitors. The fight features No. 10 Karol Rosa (18-7) against No. 12 Nora Cornolle (9-2). Rosa opened as the -160 favorite over the +135 Cornolle. Today, Rosa is listed at -180, while Cornolle comes in at +145.

Rosa has picked up more bets (54 percent) and more money has come in on her (59 percent).

The pick is for Cornolle to pull of the upset in a decision win.

UFC Vegas 108 Fight Card: Betting Odds, Line Movement And Predictions – Neil Magny Vs. Elizeu Zaleski dos Santos

In this contest, we have two veteran welterweight competitors in Neil Magny (29-13) and Elizeu Zaleski dos Santos (25-9-1). When the odds opened for this scrap, Magny was the +200 betting underdog to the -250 Dos Santos. The line has tightened for this one. Today, Magny is +150 and Dos Santos -185.

While Magny is the betting underdog, the bettors are invested in him with 74 percent of the bets and 75 percent of the handle on Magny.

The pick is Zaleski to defeat Magny via decision, but there’s a chance of a knockout as well.

UFC Vegas 108 Fight Card: Betting Odds, Line Movement And Predictions – Danny Silva Vs. Kevin Vallejos

Opening the UFC Vegas 108 main card is a featherweight scrap between Danny Silva (10-1) and Kevin Vallejos (15-1). Vallejos opened as one of the biggest favorites on the card at -425. Today, he is -450. Silva was a +310 underdog, and is now listed at +340.

As is often the case in fights with lopsided odds, bettors are looking for a upset. Silva has 81 percent of the bets and 69 percent of the handle.

The pick is for Vallejos to pick up a knockout victory.
