The Mariners have made big efforts to improve the bullpen this season, and adding veteran Warren is just another step in that direction. He is a versatile pitcher who should provide solid relief in the middle innings for Seattle.

This move helps the Yankees with their international signings, while also alleviating salary for other pursuits. Warren is enjoying a solid 2018 campaign, but New York felt comfortable with their bullpen to move him on.

It is rare at this time of the season for a player to move from contender to contender, but that is exactly what Warren has done here. Therefore, his fantasy value remains the same.
