Roman Reigns has held the WWE World Heavyweight Championship since WrestleMania 32, and his title run is expected to continue into the summer. The next face of WWE is a heavy favorite to win his championship match at Extreme Rules 2016 on Sunday night.

WWE has been pushing Reigns to be a top star and the unofficial successor to John Cena for nearly two years, and now that he has the title, he’ll likely remain the champ for the foreseeable future. AJ Styles has emerged as one of WWE’s top babyfaces, but it’d be a major upset to see him take the belt at the upcoming pay-per-view. Paddy Power gives him 5/1 odds to defeat Reigns in Sunday’s WWE World Heavyweight Championship match, and Reigns is a 1/10 favorite.

The United States Championship is the only title that is favored to change hands. Having held the belt since before WrestleMania 32, Kalisto is a 3/1 underdog against Rusev, who has 1/5 odds to become a two-time U.S. champ.

Three other wrestlers will compete for The Miz’s Intercontinental Championship, but the odds are in his favor to retain. He’s a 1/5 favorite against Cesaro (6/1), Kevin Owens (9/1) and Sami Zayn (12/1).

Charlotte (1/10) is favored to beat Natalya (5/1) in the WWE Women’s Championship Match, and The New Day (1/5) are favored to defeat The Vaudevillains (3/1). Both Charlotte and The New Day have been champs since last summer.

Dean Ambrose is a heavy favorite (1/7) to defeat Chris Jericho (4/1) in the first ever Asylum Match. Ambrose beat Jericho three weeks ago at WWE Payback.

Extreme Rules starts at 8 p.m. ET, and it can be purchased on PPV for $49.95 (standard definition) or $54.95 (HD). It will be broadcast on WWE Network, which costs $9.99 per month. New subscribers can watch the live stream online for free, since they get their first month of the network free of charge.
