Arizona has activated Tommy Troy, the Diamondbacks announced, with the infielder returning from a shoulder injury.

The timing matters. The D-backs have been piecing together a roster in motion throughout this stretch run — Ketel Marte returned from a stint away earlier in the week, Blake Walston was reinstated from the 60-day IL to bolster the bullpen, and Corbin Burnes is targeting a return to the rotation after a 15-month absence. Troy's activation adds another body back to a lineup that has been managing its share of wear, including Corbin Carroll playing through low back discomfort, though Carroll has not expected to miss time.

What remains unconfirmed

Per Joshua Koch at MLB.com, the report does not specify the corresponding roster move required to make room for Troy, nor does it detail the severity or exact timeline of the shoulder injury that kept him out.

What to watch: how Troy is deployed as Arizona pushes through the final weeks of the season, and whether the club's returning pieces can stay healthy long enough to matter.
