One day after concluding the season with another last-place finish (75-87), the Mariners announced the retention of the entire coaching staff with the exception of hitting coach Chris Chambliss, who was fired after the club finished at the bottom of most offensive categories.

“We will begin an immediate search for a new hitting coach,” GM Jack Zduriencik said in a club statement. “On behalf of the Mariners organization, I want to thank Chris for all of his hard work and dedication over the past two seasons.”

Manager Eric Wedge also thanked Chambliss and said the current staff is at work on 2013.

“As we go through the process of getting this team where we want it to be, the coaches are a big part of it,” he said. “We had meetings today, and the coaches and staff will be in contact with our players all winter.”

Returning are bench coach Robby Thompson (infield); pitching coach Carl Willis; first base coach Mike Brumley (outfield/baserunning); third base coach Jeff Datz (catching); bullpen coach Jaime Navarro and bullpen catcher Jason Phillips.

Chambliss, 63, has had 15 seasons as a big league hitting coach, and 43 in professional baseball.

Chambliss didn’t scout of sign any of Seattle’s hitters, but takes the fall for the Mariners ranking last in the American League in runs scored (619), hits (1,285),  batting average (.234), on-base percentage (.296), slugging (.369), OPS (.665) and total bases (2,027). The Mariners were 11th in home runs (149).

In addition to booting Chambliss, the Mariners said second baseman Dustin Ackley and shortstop Brendan Ryan underwent arthroscopic surgeries.

Ackley had a bone spur removed from his left ankle and Ryan had one removed from his right elbow. Eachwill begin rehab Friday and are expected to be ready for spring training in February.
