"He's done it many, many times, so I'm sure he has his own gig that way," Sveum said.
Sveum said that Villanueva will pitch in multiple roles and that the Cubs will not have a typical long man waiting for a starter to falter.
"Obviously, he's built up to pitch very long, but he's not that typical long guy where you sit there and you say, 'Oh, we have to save him in case our starter blows out in the first inning or gets beat up,'" Sveum said. "You don't do that with him. He'll just be one of the guys."
