The Arizona Diamondbacks have disappointed and the internal drama extends beyond the uncertain futures of Chip Hale and the club's top executives.

Mike Bell, the team's farm director, and senior vice president of baseball operations De Jon Watson are at odds over how to approach player development, according to sources.

Some believe Bell might leave the Diamondbacks if Watson remains on board.

"There is no truth to that rumor," general manager Dave Stewart said. "It's no different than most workplaces. Ups and downs."

The Diamondbacks did not exercise contract options on Stewart and Watson by an Aug. 31 deadline.
