Frank Mattox, who had been a scout with the Mariners for 17 years, died at his Peoria, Ariz., home Sunday night.

What did he do for the Mariners? Mattox held roles at all levels of the team's scouting ranks.

"It is difficult to put into words the depth of the Mariners' sadness upon hearing the news last night," Mariners president Chuck Armstrong said in a release. "The thoughts and prayers of the entire Mariners organization are with the Mattox family as they deal with this tragedy."
