PHOENIX -- Arizona manager A.J. Hinch says third base coach Chip Hale and first base coach Lorenzo Bundy will not return.
Meanwhile, the Diamondbacks gave a two-year contract extension to bench coach Kirk Gibson.
Hinch says batting coach Jack Howell and pitching coach Mel Stottlemyre will return, and bullpen coach Glenn Sherlock has also been offered a contract for next year.
Hinch announced the changes during a season-ending news conference on Monday at Chase Field. He said he is conducting a search for replacements for Hale and Bundy.
