Waldo Cortes-Acosta feels it’s time he takes a step up in competition to take on one of the world’s best in his division. The rising heavyweight wants to get a ranked opponent following his dominant win over Olympic medalist Robelis Despaigne this past Saturday at UFC on ESPN 56 , and he already has a name in mind. Cortes-Acosta (12-1 MMA, 5-1 UFC) wants to get matched up against kickboxing standout Jairzinho Rozenstruik , who’s currently in the top-15 rankings of the UFC’s heavyweight division. “If they could give me Jairzinho, that would be perfect,” Cortes-Acosta told MMA Junkie in Spanish .
