Cardinals pitcher Michael Wacha will undergo an MRI on his injured shoulder Monday, and if the tests go how the team expects, he'll begin a throwing program soon after, the St. Louis Post-Dispatch reports.
Wacha is eyeing a return to the team in September, and while he could come back as a reliever, general manager John Mozeliak "has a feeling" he'll return as a starter. His role for the remainder of the season will be determined by whatever the team believes is best for his long-term health.
