Arodys Vizcaino stopped in the middle of the clubhouse and did a few dance moves. He swiped a piece of fruit from the table and began chatting with two Cubs staffers.

That Saturday morning snapshot might have shown Vizcaino’s state of mind. This is someone who’s comfortable and confident almost two full years after the Tommy John surgery that knocked him off the fast track and wiped out his last two seasons.

“I feel very strong right now,” Vizcaino said. “I want to be (there) Opening Day.”

About two hours later, president of baseball operations Theo Epstein, general manager Jed Hoyer and a group of team officials watched Vizcaino throw 25 pitches in a bullpen session at Cubs Park. They believe he has what it takes to one day become a high-end closer or a frontline starter. That’s why they made him the centerpiece of the Paul Maholm/Reed Johnson trade with the Atlanta Braves in July 2012 — four months after Dr. James Andrews reconstructed his right elbow.
