According to Bob Nightengale of USA Today, the Arizona Diamondbacks have fired GM Josh Byrnes and manager A.J. Hinch.

Bench coach Kirk Gibson has been promoted to interim manager. Jerry Dipoto, the vice president of player personnel, will be the interim GM.

“I appreciate the commitment and dedication that Josh and A.J. demonstrated during their tenures,” owner Ken Kendrick said in a statement. “Their dismissal is a significant decision, but one that we find necessary in order to achieve a direction of winning consistently on the field again. We have a number of talented players, but obviously, see great room for improvement. We look forward to bringing permanence to these two baseball leadership roles.”

Jon Paul Morosi of FOXSports says the Diamondbacks will eat more than $7 million. Byrnes was under contract through 2015.

“These decisions come as a first and major step in our thorough evaluation of our team,” team president Derrick Hall said in a statement. “We have all been disappointed in the results over the last few years, and we have come to the conclusion that a change in the leadership of our baseball operations staff is necessary at this time. This franchise has enjoyed tremendous success over the years and we want to get back to our winning ways. The loyal staff of this organization, as well as all of our fans, hopes for and deserves better results on the field.”
