With a focus on reinvigorating a farm system that had been short on talent and prospects in past seasons, but also had received an influx of talent thanks to the myriad trades this offseason, the Mariners announced their player development staff and coaching staffs for the each minor-league affiliate going into the 2019 season.

Mariners’ director of player development Andy McKay retained a large group of coaches and coordinators from last season, but several have changed positions within the organization.

Player Development Coordinators

  • Field Coordinator: Carson Vitale
  • Special Assistant, Player Development: Alvin Davis
  • Special Assistant, Player Development: Dan Wilson
  • Special Assignment, Pitching Coach: Pete Harnisch
  • Pitching Coordinator: Max Weiner*
  • Hitting Coordinator: Hugh Quattlebaum
  • Assistant Hitting Coordinator/Catching Coordinator: Tony Arnerich
  • Coordinator, Latin America Development: Cesar Nicolas
  • Minor League Video Coordinator: Craig Manning

The coordinator staff remains largely the same, though Mike Micucci, who served as coordinator of instruction last season, wasn’t retained. The Mariners no longer have that position. Weiner replaces Oscar Marin as minor-league pitching coordinator. Marin left the organization for a big-league job with the Rangers. Weiner is the founder of The Arm Farm, a company that does private training for pitchers. He previously worked for the Indians. Nicolas moves up from being a manager of the Mariners’ team in the Dominican Summer League to a new position created to oversee the overall development of the organization in Latin America.

High Performance Coordinators

  • Coordinator, Minor League Medical/Athletic Training: John Walker
  • Coordinator, Minor League Rehabilitation: Michael Feliciano

  • Rehab Coach: Moises Hernandez
  • Athlete Monitoring: Dan Adams
  • Pitching Strategist: Trent Blank*
  • Pitching Strategist: Forrest Herrmann*
  • Hitting Strategist: Jarret DeHart

This staff is something that has been supplemented with a handful of hires. With the much-publicized removal of Dr. Lorena Martin from director of high performance, there will not be a single overseer of this staff. Sources said Martin’s responsibilities will be divided among staff.

Brown, who is the winningest manager in Rainiers history with a 433 victories in seven-plus seasons in Tacoma, returns after managing at the Class AA level the past three seasons. Brown replaces Pat Listach, who was not retained. Painter has been a fixture in Tacoma and is a favorite with pitchers because of his work with pitching mechanics.

The former Oregon State and Lake Stevens standout has been a manager in the organization for the past three seasons. He spent the past two seasons in the High-A California League, managing Modesto. This will be his first season at the Class AA level and he’s expected to have a loaded team featuring prospects Kyle Lewis, Evan White and Justin Dunn.
