Phillies Rule 5 pick Noah Song has been shut down due to back tightness, per Alex Coffey of the Philadelphia Inquirer. He’s had an MRI and will be reevaluated next week, but it appears he won’t be ready to start the season.

Song, 25, is an interesting case, given he’s spent the past three years in the navy after being drafted by the Red Sox in the fourth round of the 2019 draft. He’s also not been fully discharged, only placed in active reserve, which means he’ll be able to play baseball. It does mean he’ll still have navy commitments though, with an earlier report stating he’s effectively on part-time duty, which still requires one weekend per month and two full weeks each year. It’s not clear how that would’ve played out over the season.

In any case, Song was looking to get back up to speed quickly after three years out. As a Rule 5 draftee, the Phillies would have to keep him on the active roster for the entire season, or place him on waivers and send him back to the Red Sox if he clears. The injury does change things somewhat, as should Song open the season on the injured list the Phillies can still send him on a rehab stint to the minors for up to 30 days. He still can’t be optioned to the minors, but the Phillies would just need to ensure he spends at minimum 90 days on the active roster this season.
