Marvin Vettori says he never buys into the hype surrounding any UFC fighter, including himself. He's unimpressed with celebrated middleweight champion Israel Adesanya ahead of their rematch on Saturday in the main event of UFC 263. The much-anticipated showdown takes place at the Gila River Arena in Glendale, Ariz. The main UFC 263 fight card is slated for 10 p.m. ET. The third ranked Vettori, who is getting his first title shot, fell short by split decision to Adesanya in 2018, but the challenger has insisted that he will prove he's the best middleweight in the promotion by dominating the rematch.

Adesanya is a -240 favorite (risk $240 to win $100), while Vettori is priced at +200 in the latest Adesanya vs. Vettori odds from William Hill Sportsbook. In the co-main event, flyweight champion Deiveson Figueiredo is the -240 favorite in the UFC 263 odds as he takes on Brandon Moreno (+200) in a rematch of their December classic that ended in a draw. Before you make any UFC 263 picks of your own, make sure you see the MMA predictions from SportsLine MMA analyst Ian Parker.

A former fighter who's been in the industry for 15 years, Parker has managed some of the world's best, including former UFC middleweight champ Chris Weidman, Costas Philippou and Gian Villante. Parker trained alongside UFC Hall of Famer Matt Serra. Now, Parker breaks down fights and makes betting picks for the Voice of the UFC, Jon Anik.

Parker is coming off a mind-boggling 2020 season. On the Anik & Forian Podcast, Parker went an astounding 58-14, returning $9,465 to $100 bettors who followed him. He hit 11 of his 17 underdog picks and 19 of 30 main events. Overall, Parker nailed an astonishing 81 percent of his plays.

Parker has already proven his mettle to SportsLine members. Last week at UFC Fight Night, he encouraged SportsLine members to back veteran Marcin Tybura (-165) against Walt Harris (+145) in the heavyweight co-main event. Tybura scored a first-round stoppage to give Parker's followers another easy winner. Anyone who has followed Parker has seen massive returns.

Now, with UFC 263 in sight, Parker has studied the MMA odds and UFC 263 card from every angle and released his top selections. A parlay of those MMA picks would pay nearly 7-1. Those picks are available at SportsLine.  

UFC 263: Adesanya vs. Vettori 2 preview

Parker knows Adesanya (20-1) is still widely considered one of the most skilled fighters in the division, though his growing cloak of invincibility was cracked amid the loss to Blachowicz.

Even so, the brash former kickboxer has mostly dominated the middleweight division since joining the UFC more than three years ago. He stopped former champion Robert Whittaker to win the unified belt in November 2019 and has gone unchallenged in two subsequent title defenses against previously unbeaten Paulo Costa and Yoel Romero, who has since been cut by the promotion.

However, the one stern test the champion has faced came in his second UFC fight against the rage-driven Vettori, whose nonstop pressure nullified Adesanya's precision striking game.

Adesanya got his hand raised by split decision amid a protest from Vettori (17-4-1), who insisted he won and vowed to exact revenge. Now, the Italian brawler will get his chance on the merit of five consecutive victories since that controversial defeat. He took a lopsided decision over rising prospect Kevin Holland in their April fight. You can see Parker's coveted Vettori vs. Adesanya picks here.

Top UFC 263 predictions

We'll share one of Parker's UFC 263 predictions here: He is backing Alexis Davis (+180) to pull the upset of Pannie Kianzad (-210) in a matchup of women's bantamweight prospects.

Davis (20-10) is an eight-year UFC veteran and perennial contender who has shared the cage with some of the division's biggest names. She endured a three-fight losing streak against upper-tier competition, with all the losses coming by decision, before bouncing back with a win over Sabina Mazo in February. The 36-year-old Canadian has 10 career stoppage wins to her credit.

Kianzad (14-5) has notched three consecutive decision wins against fellow prospects and will likely crack the top 15 in the UFC rankings with a fourth straight victory Saturday. The 29-year-old Iranian hasn't lost since falling short in her UFC debut in July 2019.

"Davis is smart enough to know where she has the edge and will implement her ground game to get the win," Parker told SportsLine.

Parker also has strong picks for Adesanya vs. Vettori 2 and other fights on the UFC 263 card. He's also backing a "better and faster striker" to get a convincing win. Those selections are only available here.
