The Yankees have traded swingman reliver Adam Warren to the Seattle Mariners in exchange for $1.25 million in international signing bonus pool money.
Warren appeared in 24 games for the Yankees this season, and is a free agent at the end of the year. He posted a 2.70 ERA (3.30 FIP) and a career-high 11.1 K/9. In his Yankees career, he has a 3.18 ERA as both a starter and reliever (246 total appearances).
The Yankees traded Warren to the Chicago Cubs with a player to be named later after the 2015 season to acquire Starlin Castro. They ended up getting Warren back as part of the return in the Aroldis Chapman trade of 2016.
