SEATTLE -- Mariners general manager Jerry Dipoto made a couple of moves to bolster his team's bullpen for the playoff run on Monday, acquiring veteran lefty Zach Duke and cash from the Twins in exchange for Minor League prospects Chase De Jong and Ryan Costello.
In a second deal, Seattle acquired right-hander Adam Warren from the Yankees for international bonus pool money, a source tells MLB.com's Mark Feinsand.
Duke provides a second left-handed setup man to go with James Pazos, who became the primary southpaw after the club released veteran Marc Rzepczynski in June.
