Cain Velasquez has been the UFC heavyweight champion for less than a week; however, Vegas mixed martial arts (MMA) odds-makers wasted little time released the betting odds on his first title defense. Even though the fight date is still unknown the Mexican-American champ as the -200 favorite versus Brazilian Junior dos Santos (+160).

Last Saturday evening, Velasquez turned in a jaw-dropping performance, scoring a first-round TKO over then-champ Brock Lesnar. Despite Lesnar’s imposing physique, strength and athleticism, Velasquez unleashed big punch after big punch en route to referee Herb Dean’s stoppage at 4:12 of the first round.

Even more impressive than his assault on Lesnar’s face, was how he was able to get back to his feet quickly after two of Lesnar’s takedowns.

The newly crowned champ won’t be able to sleep on his first title defense as dos Santos is the No. 5 MMA heavyweight in the world according to Sherdog.com. Dos Santos is a Brazilian jiu-jitsu brown belt fighting under MMA legends Antonio Rodrigo Nogueira and UFC middleweight champion Anderson Silva.

Despite his brown belt, dos Santos prefers keeping his fights off of the mat. Since entering the UFC in October of 2008, the 6’4”, 240-pounder has knocked out just about everyone in his path en route to a flawless 6-0 record inside the UFC Octagon.

In his UFC debut, JDS knocked out Fabricio Werdum—yes, the same Werdum who upset Fedor Emelianenko a few months ago—with a highlight-reel uppercut in the first round. Since, the challenger has defeated other big names in the UFC heavyweight division including Mirko Cro Cop, Gabriel Gonzaga and most recently Roy Nelson.

Versus Nelson, dos Santos won a very lopsided decision; it was the first time one of his bouts went to a decision in his 13-fight professional career. The Brazilian once again put his striking prowess on display; however, he was not able to knock out the hard-headed Nelson. Most impressive, dos Santos was able to thwart numerous takedown attempts by the rotund Nelson; which is exactly what he’ll have to do if he expects to take the belt away from Velazquez.

The new champ is perhaps the best well-rounded fighter in the UFC heavyweight division. A decorated collegiate wrestler at Arizona State, Velasquez has silenced his critics that said he lacked “knockout power."

Since his UFC debut in April of 2008, the undefeated Velasquez KO/TKO’d six of his seven opponents. His first-round devastating KO of Nogueira last February was only the second time “Big Nog” got knocked out in his 40-fight career.

Despite the dominating work Velasquez put in last weekend, the UFC betting crowd still isn’t impressed as the early bettors are backing underdog dos Santos. When the Velasquez vs. dos Santos betting odds earlier this week, the champion was a -240 favorite.

Thanks to one-sided dog betting, Cain is currently holding steady at -200. However, as the fight approaches, don’t be surprised if the betting odds move back out to closer where they opened. In other words, if you plan on betting on Cain, jump on the early odds.
