Diamondbacks Announce Roster Moves Amid Arenado Injury Concern
The Arizona Diamondbacks announced roster moves Monday; specific details were not disclosed in the club's post, with Nolan Arenado's status still unresolved.

The Arizona Diamondbacks announced roster moves Monday, per the official club account, though the post linked to a page rather than spelling out the specifics — leaving the exact nature of the moves unconfirmed at this writing.
The backdrop
The timing is notable. Nolan Arenado exited Arizona's game against Atlanta in the 4th inning with left trunk discomfort and expressed concern about the injury, with an MRI expected. An IL stint was described as possible. Meanwhile, Ketel Marte — who had been scratched from Saturday's lineup against the Braves with left knee soreness — returned to the lineup Sunday after missing one game.
With Arenado's availability uncertain and the club already having made a bullpen swap the day prior — selecting RHP Dennis Santana from Triple-A Reno and designating LHP Philip Abner for assignment — Monday's announcement could reflect any number of responses to the current roster situation. But that would be inference, and the club has not specified.
What we don't know yet
The substance of Monday's moves remains unconfirmed. Until the linked details are available, the only established fact is that the Diamondbacks made roster moves and chose to announce them through official channels.
