The Brewers reinstated File (elbow) from the 60-day injured list Sunday and optioned him to Triple-A Nashville.
File will stick around in Nashville after he completed his third rehab outing with the affiliate Saturday, and his seventh rehab start overall. The 25-year-old right-hander has been on the shelf all season while recovering from the surgery he required in the spring to address a fractured elbow, but he looks to be fully built up for a spot in the Nashville rotation. He was dominant in Saturday's 11-1 win over Toledo, striking out eight over 5.2 innings while permitting one run on two hits and no walks.
