Jorge Julio: Not the Answer

Is there some hidden agenda amongst major league baseball teams that I'm not aware of that says Jorge Julio MUST be a closer? It's literally been 5 years, 2002, since Jorge Julio has been an effective closer. Last year was Julio's best season in the past half decade. He finished the year with an ERA of 3.83. Julio shouldn't even be in the majors right now, let alone closing. Don't expect him to keep his current job with the Marlins. He probably won't even finish the season with them.
