The Arizona Diamondbacks have begun the search for a new manager after opting to dismiss Kirk Gibson on Friday.
Gibson initially joined the Diamondbacks as bench coach in 2007 and was promoted to the top job, initially on an interim basis, in 2010.
He was duly named as the National League's manager of the year in 2011, but leaves with an overall record of 353-375, having seen his side struggle badly this season.
Arizona, who hired Dave Stewart as their new general manager on Thursday, have combined 63 wins with 96 defeats in 2014 and sit rock bottom of the NL West division.
The team's chief baseball officer, Tony La Russa, said in a news release: "Kirk has done an admirable job under difficult circumstances and we are grateful for his professionalism and his dedicated service to the organisation over the past eight years.
"We feel like it is time for a fresh start, and with our recent restructuring in baseball operations, we want to get started immediately moving in a new direction."
Bench coach Alan Trammell has been relieved of his duties in addition to Gibson.
"We are also appreciative of Alan Trammell for all that he has done for the D-backs and have great respect for what both men have accomplished in the game of baseball," added La Russa.
