When the Marlins open the second half of the season Friday night at Marlins Park against the Washington Nationals, the ninth inning will no longer belong to Heath Bell. In fact, the closer's job won't belong to anybody. Manager Ozzie Guillen, on his weekly appearance on the Dan Le Batard Show on 790 The Ticket on Tuesday, said he's going to with a closer-by-committee approach until Bell — he hopes — regains his form. "I'm going to go by committee, see who throws the ball better," Guillen said. "I will talk to [Bell] when we come back from the All-Star break and explain to him why we're going to do this. Hopefully, he'll come back and start throwing the ball better and then he'll go back to his role.
