The Mariners have announced their 2018 player development staff, including the managing and coaching positions for their seven affiliates. There wasn’t much change within the coaching staffs with the managers all remaining the same with the exception of Denny Hocking taking over at Class A Clinton, which had two managerial changes last season.

As for the player development coordinators, there was some turnover. Andy McKay, the Mariners’ director of player development, brought back Mike Micucci to coordinate all of the instruction. Mariners stalwarts Alvin Davis and Dan Wilson remain as special assistants.

Here’s the list of assignments with a few notes.  (* denotes a newcomer to the organization.)

Player Development Coordinators:

  • Coordinator of Organization Instruction: Mike Micucci
  • Field Coordinator: Carson Vitale*
  • Special Assistant, Player Development: Alvin Davis
  • Special Assistant, Player Development: Pete Harnisch
  • Special Assistant, Player Development: Dan Wilson

  • Organization Pitching Coach: Cody Buckel*
  • Organization Pitching Development/Rehab Coach: Brad Mills*
  • Minor League Video Coordinator: Craig Manning
  • Coordinator of Professional Development: Leslie Manning

Perhaps the most interesting name of the group is Cody Buckel, who is just 25. He was once considered to be a top pitching prospect and a phenom with the Rangers, but then he developed “the yips” and couldn’t throw a strike anymore. He tried to make a comeback with the Angels last season with minimal succes, but now he’s gone to coaching.

Triple-A Tacoma Rainiers

  • Manager: Pat Listach
  • Pitching Coach: Lance Painter
  • Hitting Coach: Dave Berg

Last season’s staff returns for another year. This will be Listach’s fourth season as Rainiers manager. There was some thought he might find another job on a big league staff or even get bumped up to the Mariners’ big league staff. He’s a pro and well-liked and respected by his players. Painter has been with the organization for 12 years. He’s considered to be a bit of a mechanics guru. His most notable work was fixing James Paxton and his arm slot. Painter was briefly considered for the Mariners’ bullpen coach job this offseason.

  • Manager: Daren Brown
  • Pitching Coach: Ethan Katz

Brown has a 1156-1044 record over 19 seasons as a manager in the organization. Katz is back with Arkansas for a second season.

Single-A Modesto Nuts

The former Lake Stevens High and Oregon State standout is considered a rising star in the organization.
