The additions of pitchers Zack Greinke and Shelby Miller had the Arizona Diamondbacks facing upgraded expectations this season.
When the team took a step back instead of forward, something had to change.
General manager Dave Stewart and manager Chip Hale will not be back. Chief Baseball Officer Tony La Russa will be, though it's unclear in what role.
Coming off a second disappointing season, the Diamondbacks parted ways with Stewart and Hale on Monday in the latest shake-up for an organization seeking consistency.
"We did not see the trend line moving in the right direction," Diamondbacks managing general partner Ken Kendrick said.
