The Arizona Diamondbacks announced the reinstatement of right-hander Drey Jameson from the 15-day injured list and, in the corresponding move, designated right-hander Zack Littell for assignment, per AJ Eustace at MLB Trade Rumors.

Jameson had been sidelined since late July with right hip inflammation. Littell's designation starts a seven-day window in which Arizona must trade, release, or outright him to the minors.

With the move, the Diamondbacks' 40-man roster sits at 39.

The bigger picture

The roster shuffle arrives during a turbulent stretch for Arizona. The club has been managing the ongoing situation surrounding Ketel Marte, who was placed on the injured list earlier this week after a series of roster and off-field developments. Against that backdrop, getting Jameson back into the mix is a straightforward piece of good news.

What remains unconfirmed

The report does not specify Jameson's expected role upon return, nor does it detail what Arizona intends to do with Littell beyond the designation itself.
