Just days from the end of an awful season, the Arizona Diamondbacks fired manager Kirk Gibson.

The firing was announced Friday, 15 minutes before a news conference to introduce new Diamondbacks general manager Dave Stewart.

“It was my trigger to pull,” chief baseball officer Tony La Russa said.

Bench coach Alan Trammell also was dismissed, but will stay on to manage the final three games.

“We just decided that being fresh, starting fresh with not just the upstairs leadership team but downstairs, is more consistent with what we are doing as an organization,” La Russa said.
