Arizona Diamondbacks chief baseball officer Tony La Russa announced Monday that the team's entire coaching staff will return in 2016 except pitching coach Mike Harkey.
The Diamondbacks rebounded for a 79-83 season just one year after dropping 98 games.
Harkey's firing is a bit of a surprise as the team finished 17th in xFIP and 10th in the National League. They showed improvement as a whole in the second half, though the lack of season-long development in several young pitchers may have been a contributing factor.
