Longtime Mariners scout Mattox passes away

PEORIA, Ariz. -- Longtime Mariners pro scout Frank Mattox died Sunday night at his home in Peoria, collapsing suddenly while sitting down to watch the Academy Awards on television, according to a team spokesman.

Mattox, 49, spent the past 18 years working for the Mariners and was the team's scouting director from 1998-2003. He served as director of player development from 2004-07 before returning to a role in pro scouting.

"It is difficult to put into words the depth of the Mariners' sadness upon hearing the news last night," said Mariners president Chuck Armstrong. "On behalf of the Mariners organization and ownership, we wish to extend our deepest sympathy to Frank's family -- his wonderful wife, Sylvia, and three beautiful children, Myles, Blake and Marisol.

"The thoughts and prayers of the entire Mariners organization are with the Mattox family as they deal with this tragedy."

Before coming to the Mariners, Mattox worked for the Colorado Rockies and was their Scout of the Year in 1993. He played seven seasons of Minor League ball in the Brewers' system after earning his Bachelor's of Science degree in political economy of natural resources from the University of California at Berkeley.

"I've known and worked with Frank for nearly 20 years," Armstrong said. "His positive personality, scouting acumen and team-first attitude will be missed among our baseball staff and in the Mariners' family."

In addition to his wife and children, Mattox is survived by his mother, Vel, and father, Frankie.
