PEORIA, Ariz. -- With Opening Day now just 11 days away, the Mariners trimmed their Major League camp to 40 players on Sunday, sending four players to the Minor League side, including promising relief prospect Art Warren.
Warren, the Mariners' No. 8 prospect per MLB Pipeline, will likely open the season at Double-A Arkansas after pitching last season for Class A Advanced Modesto, according to manager Scott Servais.
Also sent down were right-handed relievers Mike Morin and Shawn Armstrong and outfielder John Andreoli. The moves leave Seattle with 40 players in big league camp.
