We are seeing a lot of relievers change hands this trade season. Kelvin Herrera, Zach Britton, Brad Brach, Roberto Osuna, and more already have new teams and more are on the way.
One team that has pieces to sell that has been laying relatively low has been the Minnesota Twins. The Twins have dealt Eduardo Escobar, but beyond that they have been waiting for the market to come to them. It looks like they are done waiting around.
Zach Duke has been in the major leagues for a long time and has played for a number of clubs. While his best days are behind him (he put up four 2+ fWAR season with the Pirates over a decade ago), he is putting up a strong season for the Twins with a 3.62 ERA and 2.68 FIP while accumulating 0.8 fWAR in 2018.
In exchange, the Twins are getting the Mariners #28 overall prospect RHP Chase DeJong as well as infield prospect Ryan Costello. DeJong has middling stuff, but does possess a good breaking ball as well as deceptive delivery. Costello was Seattle’s 31st round pick in 2017 and has posted a .845 OPS in 2018 while playing mostly first base in high-A.
