DeLauter was placed on the 7-day injured list at Triple-A Columbus on Friday with a right hamstring strain.
The 22-year-old had posted an 1.147 OPS in six games after being promoted to Columbus, putting himself on the radar for a potential September call-up. While the severity of the strain is unclear, DeLauter would appear to now be a long shot to get a late-season look in the majors. He has loads of talent but just can't stay on the field, having missed ample time the last two seasons with foot and other lower-body problems.
