The Mariners assigned Weigel to their minor-league camp Monday, Ryan Divish of The Seattle Times reports.
Though his resume includes four big-league relief appearances, Weigel never looked like a good bet to make the Mariners' Opening Day bullpen after signing with the team on a minor-league deal late in the offseason. His lack of a 40-man roster spot means that he'll have to impress at Triple-A Tacoma before warranting consideration for a possible promotion to the big club.
