Baldwin was diagnosed with a Grade 1 right oblique strain Tuesday, Daniel Alvarez-Montes of ElExtraBase.com reports.
Baldwin landed on the injured list earlier Tuesday with an oblique strain, and now that he's been confirmed to be dealing with a relatively mild injury, he may not need much more than a minimum stay on the IL. With Sean Murphy (finger) also on the shelf, Atlanta will use a combination of Sandy Leon and Chadwick Tromp behind the dish until Baldwin returns.
