"Ruf is not a rightfielder," Amaro said. "I think he can fill in for us. I think he can fill in in certain areas, but I can't sit here and tell you that he's an everyday player for us. He's going to have to fight for a job in some way, shape, or form. Can he add some depth to our bench, to our club overall? Can he play a little left, can he play a little right, can he play a little first and give [Ryan] Howard a blow? He can become valuable in that regard.
