Ottavino, the Cardinals' first-round Draft pick in 2006, made five appearances before being sidelined with a shoulder injury. It was initially thought that he would require surgery, but he's come along extremely well with a non-surgical rehabilitation.
Although he's throwing on the side now, La Russa said Sunday that he will not appear in games this year.
"Absolutely not," the manager said. "I don't know what that serves, except risk. He's out there pitching under control. He goes in a big league game and starts to air it out, he's not conditioned to do it."
