With multiple trades made this past offseason plus the previous few drafts, the Mariners have assembled a large group of talented young outfield prospects throughout their organization. To supplement their growth and development, they made a notable hire to help the process.

On Friday, the organization announced that former Mariner outfielder Mike Cameron has been added to the player-development staff. Cameron’s official title is “special assignment coach.” His responsibilities will include working with Mariners prospects at all levels of the organization, with a focus on outfield defense and base running. Besides working with minor-league players, Cameron will spend some time working with the big-league team.

Cameron started work immediately. He was in uniform with Class AA Arkansas on Friday night. The Travelers have three solid outfield prospects, who are all ranked in Baseball America’s Top 30 prospects for the organization —  Kyle Lewis (No. 8), Jake Fraley (No. 15)  and Dom Thompson-Williams (No. 18).

Manager Scott Servais met with Cameron to discuss the role when the team was in Chicago a few weeks ago.

“Mike obviously had a great career and really good run here with the Mariners for awhile,” Servais said. “It’s a great opportunity to bring somebody with a ton of experience into the organization from an outfield, base stealing, hitting home runs aspect and all that stuff. He’s had quite a career. I’m glad to have him on board.”

Besides the trio at Arkansas, the Mariners have two outstanding prospects in Jarred Kelenic (No.2) and Julio Rodriguez (No. 5) in West Virginia and Braden Bishop (No. 13) in Tacoma.
