Miller (hips) was reinstated from Triple-A Toledo's 7-day injured list Saturday, Emily Waldon of Baseball America reports.
Miller landed on the 7-day IL in late March due to injuries to both sides of his hips. He has been cleared to return to Triple-A after posting a 0.89 ERA, 0.84 WHIP and 22:6 K:BB in 20.1 frames across six rehab outings in the lower minors.
