MILWAUKEE — When the Cardinals rummaged the waiver wire and free-agent aisle for pitching help earlier this season, they called it the "churn" and they did it looking for any, all, some, just some innings.
With a tightening grip on wild-card spot and two weeks of games remaining against the same two opponents, they have another reason to 'churn.'
Strategy.
Streamlining.
And, perhaps most intriguing of all, preparation for how Jack Flaherty and Dakota Hudson will yet be used when they return from injury.
A few hours before first pitch Monday evening in Milwaukee, the Cardinals removed righthander Daniel Ponce de Leon from the active roster to add lefty Brandon Waddell.
