When you’re watching a Bellator event, you can only hope that a memorable finish or two will make up for the general lack of star power compared to those other guys. And oh man, did last night’s Bellator 90 event in West Valley City, Utah, deliver the goods, with all four fights on the Spike TV main card ending within the first two rounds, and three more stoppages featured on the prelims.

But the card’s generous helping of violence was a mixed blessing, since the list of victims included Bellator’s light-heavyweight marquee attraction, and their marketable featherweight inspirational figure. If you didn’t tune in last night, here’s what you missed:

Season 8 Welterweight Semi-Finals: Ben Saunders faced Raul Amaya for the second time in his Bellator stint, and while Killa B completely dominated their first meeting en route to a unanimous decision win, he didn’t even let Amaya out of the first round this time. Amaya was aggressive from the opening bell, but wasn’t able to find his range against the lanky Saunders, who landed counter-punches and body-kicks at will, before putting Amaya’s lights out with a left high kick.

The fight on the other side of the 170-bracket was just as quick and one-sided. Douglas Lima didn’t give Bryan Baker a chance to get in the fight, abusing Baker’s legs with low kicks for a couple minutes, then firing a devastating right hand that crumpled “The Beast” to the mat. Lima will now face Saunders in the Season 8 Welterweight Tournament Final at Bellator 93, in a rematch of their Season 5 Welterweight Tournament Final in November 2011, which Lima won by knockout.

We’ll admit it, when we first heard about Bellator, a tournament-oriented MMA organization airing to a Spanish-language audience on ESPN Deportes, we were skeptical.  But two straight weeks of viral video hits thanks to some exciting finishes piqued our curiosity, and we decided to talk with Bellator CEO Bjorn Rebney to try and figure out what this thing is all about.

CagePotato.com: You guys have had a couple good weeks on the internet with Toby Imada’s submission and then the spinning backfist KO.  That stuff makes for good viral video, but is it just a couple lucky outcomes or do you chalk it up to good planning and matchmaking?

I don’t think you can ever plan for what happened with Toby Imada and I don’t think you can ever plan for what happened with Yahir Reyes.  What I do think is this: the tournament structure, and the ability of our fighters to make their own way and determine what they make, with the overall amount being quite high, it generates a willingness on the fighters’ parts to take some risks that they might not otherwise take.  We may just be incredibly lucky to have found some amazing fighters who did amazing things the last couple of weeks, but it’s played out beautifully for us.
