"I think we've always tried to position ourselves as opportunistic," Mozeliak said. "If something comes our way, we want to be prepared. Clearly, us being connected to a lot of different things, that's just by us showing some interest. Whether that means there is traction or not, I would probably lean toward the not. But a lot of things can change."
The Cardinals have inquired about the availability of starters more accomplished than Masterson, but with a better return would come a heavier cost. If the Cardinals were to deal again, it would likely be to add one of those marquee starting pitchers.
"We're open for business to see what would happen," Mozeliak said. "I'm not overly optimistic that we'll do anything. We'll take our time, what little we have left, and see if we cannot improve."
