Undefeated flyweight Emily Corso is the latest addition to the Invicta FC roster, the promotion announced recently.

Corso is 4-0 and fights out of Oregon’s Gracie Barra Portland camp. She went 9-1 as an amateur before turning pro in 2014 and winning all four of her bouts via submission.

“The Mantis Shrimp” is a purple belt in Brazilian jiu-jitsu and has held numerous titles on the regional scene.

“I remember watching Invicta cards years ago and musing with friends how getting signed with Invicta would be the holy grail of an MMA career — real proof that you’ve ‘made it’ as a fighter. I’m grateful to have my chance to climb into the cage with the best in the business,” she said. “I’m thrilled about the possible opponents that I’ll have with Invicta. I have the utmost respect for the women of my division. I believe I’ve earned the opportunity to meet my idols as equals and I look forward to showing Invicta’s athletes and fans why that is.”
