LAS VEGAS – After a successful UFC featherweight debut, Aljamain Sterling is ready to take on the very top of the division. Sterling (24-4 MMA, 16-4 UFC) called out former title challenger and long-time contender Brian Ortega after his win at Saturday’s UFC 300 . Sterling defeated Calvin Kattar (23-8 MMA, 7-6 UFC) in a dominant decision win in the preliminary portion of the event, and he’s ready to take a step-up that will lead him to UFC gold. “Give me the next best guy,” Sterling said at the UFC 300 post-fight press conference.
