The Nationals announced today that they have designated righty Justin Miller for assignment. He had been on the 60-day injured list.

Miller, 32, was working back from shoulder issues. Though he was ready to be activated, the club obviously decided that he wasn’t going to be a significant part of the relief mix going forward. The unit has struggled badly as a whole, but is likely going to receive reinforcements in the next two days.

It’s still possible that Miller will end up clearing waivers and landing at Triple-A with the Nats, though he’d have the right to elect free agency instead. He had a strong comeback showing last year in D.C., but never got things going this season.

To open the current campaign, Miller threw 15 2/3 innings of 4.02 ERA ball with 11 strikeouts and four walks. He did rack up 18 strikeouts without a single free pass in his 12 2/3 total rehab frames, but evidently the Nats did not expect that to carry over into the majors.
