Twins trade Zach Duke to Mariners in three-player deal

Duke will help strengthen the Mariners' bullpen by providing a left-handed arm to go along with James Pazos. Both De Jong and Costello are minor leaguers with De Jong in Double-A and Costello in Single-A.

Duke has posted a 3.62 ERA and 1.58 WHIP while striking out 39 in 37 /3 innings pitched this season.
