Spence vs Porter odds: Errol Spence Jr big favorite to unify titles

Tonight’s FOX pay-per-view main event is intriguing in many ways, a welterweight unification fight featuring IBF titleholder Errol Spence Jr and WBC titleholder Shawn Porter, but there’s a clear and obvious betting favorite.

Spence (25-0, 21 KO) is being tipped to unify the belts, with odds in his favor between -800 and -1000, making him a very strong favorite indeed.

Porter (30-2-1, 17 KO) is between +494 and +705, so he’s a real underdog. The odds aren’t insane — this isn’t Dubois-Tetteh or anything — but we have a clear favorite here, and most fans are seeing it that same way. Porter’s a good fighter, but Spence is thought to be special.

In the co-feature, challenger David Benavidez is an even bigger favorite against reigning WBC super middleweight titleholder Anthony Dirrell. Dirrell (33-1-1, 24 KO) has the title because Benavidez (21-0, 18 KO) was stripped due to failing a drug test last year.

Benavidez is listed between -833 and -1250, with Dirrell between +450 and +850.

The other two fights on the pay-per-view have much tighter odds.

There’s a vacant WBA “world” 140-pound title on the line between Mario Barrios (24-0, 16 KO) and Batyr Akhmedov (7-0, 6 KO). Barrios is the favorite, but not by a lot. He’s listed between -140 and -189, with Akhmedov between +122 and +138.

The opener figures to be a gritty battle between veteran welterweights Josesito Lopez and John Molina Jr. Lopez is the favored man here, between -350 and -450, while Molina is between +250 and +320.
