The Arizona Diamondbacks fired manager Kirk Gibson Friday.

The team is guaranteed to finish in at least a tie for the worst record in the majors this season. Bench coach Alan Trammell was also relieved of his duties, though he will stay on as interim manager for the last three games of the season.

Gibson won the National League’s Manager of the Year award in 2011 when he led the Diamondbacks to the playoffs. The team went 81-81 the last two years, though, before collapsing to 63-96 this season.

Former major league pitcher Dave Stewart was named general manager Thursday and wasted little time dumping Gibson.

“Kirk has done an admirable job under difficult circumstances and we are grateful for his professionalism and his dedicated service to the organization over the past eight years,” team president Tony La Russa said in a statement. “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.”
