Boston Red Sox first-base coach Arnie Beyeler will not return for the 2016 season, the team announced Sunday.

The Red Sox announced that manager John Farrell and most of his coaches will be back for next season, but added that the contracts for Beyeler and strength coach Pat Sandora “have not been renewed.”

No reason was given for dismissing Beyeler, who was in his third year as first-base coach.

Beyeler, 51, was the Portland Sea Dogs manager for four years, 2007-10, before moving on to manage Triple-A Pawtucket for two years.

He joined Farrell’s major league staff in 2013, along with bench coach Torey Lovullo and third-base coach Brian Butterfield. Both Lovullo and Butterfield are being retained, along with hitting coaches Chili Davis and Victor Rodriguez, pitching coach Carl Willis and bullpen coach Dana LeVangie.

The Red Sox also announced that Bob Kipper, who has been assisting the major league staff, will return to his role as Pawtucket’s pitching coach next year.
