Cardinals starting pitcher Michael Wacha will move to the bullpen following his start Saturday against the Cubs, according to the St. Louis Post-Dispatch.
General manager John Mozeliak told reporters he wants Wacha to pitch out of the bullpen in higher leverage situations late in games down the stretch, likely to preserve his arm moving forward.
Wacha will likely also be next in line if the Cardinals need a starting pitcher over the final two months of the season, though Mozeliak did not confirm that.
