No one in mixed martial arts history has mastered the art of trash talking any better than Chael Sonnen. The self-professed “Gangster of West Linn” celebrates his 40th birthday on April 3.

Sonnen spent much of his career as a hired gun, though his lengthy resume includes wins over Renato Sobral, Paulo Filho, Brian Stann, Mauricio Rua and reigning Ultimate Fighting Championship middleweight titleholder Michael Bisping. The Team Quest mainstay emerged as one of MMA’s premier middleweights in 2009, when he rattled off consecutive victories against Dan Miller, Yushin Okami and Nate Marquardt. Suddenly, he was the No. 1 contender for then-champion Anderson Silva’s middleweight throne. Sonnen built heat for their showdown with provocative insults and verbal barbs, their rivalry reaching its crescendo at UFC 117 on Aug. 7, 2010 in Oakland, California. He spent four-plus rounds overwhelming Silva with takedowns and ground-and-pound before “The Spider” submitted him with a triangle armbar to retain his title in the fifth round. They fought again a little less than two years later, as Silva stopped the Milwaukie, Oregon, native with a knee to the body and follow-up punches in Round 2. Sonnen has gone 1-3 since (Vegas odds).

A onetime NCAA All-American wrestler at the University of Oregon, Sonnen’s next assignment comes as a Bellator MMA headliner on pay-per-view. He has been slotted opposite Wanderlei Silva in the Bellator 180 main event on June 24 at Madison Square Garden in New York (online betting) .
