Arroyo (oblique) completed range-of-motion and core stabilization exercises at Tropicana Field on Wednesday, Bill Chastain of MLB.com reports.
Arroyo hit the disabled list Saturday with a left oblique strain, and this appears to be the first official report of him resuming any type of physical activity. The 23-year-old was slashing a solid .264/.339/.396 across 59 plate appearances prior to his injury, and it's unknown if his DL stay will extend beyond the minimum 10 days.
