NEW YORK — Chael Sonnen took out one MMA legend, called out another, then unloaded his misery about fighting at Madison Square Garden. “I hate New York,” he bellowed in the cage. Sonnen won on the scorecards, if not the adulation from MSG fight fans, and took a unanimous decision over Wanderlei Silva in a much-delayed grudge match in a light heavyweight bout Saturday night. It was a dreadful night for Silva and fellow MMA great Fedor Emelianenko in Bellator’s MSG debut .
