Arcata’s Cass Bell made it two for two as a pro MMA fighter Saturday night, defeating Ty Costa in the second round of their MMA fight at Bellator 206.

Fighting as part of the undercard of the big showdown between Rory MacDonald and Gegard Mousasi at the SAP Center in San Jose, Bell won the fight with an armbar submission with 3:06 remaining in the second round.

“He crushed it,” Bell’s trainer John “Juan” Thompson said.

Costa came into the showdown as the more seasoned fighter of the two, having been fighting as a pro for six years.

But it was the relatively inexperienced Bell who won in rather comfortable fashion, improving to 2-0 as a pro.

The fight went exactly as planned for Bell, who fights out of the Institute of Combat in Arcata.

“We knew he was going to be tough,” Thompson said of Costa. “He came out just like we thought, pressuring and trying to drag him down and suck the life out of him. But we knew the guy would wear out. We trained for that.”

Costa is now 4-4 as a pro.

It was Bell’s second appearance at a Bellator event, having defeated Khai Wu in his pro debut as Bellator 199 in May.
