The Kansas City Royals have traded another one of their potential free agents, this time sending outfield speedster Jarrod Dyson to the Seattle Mariners for right-handed starter Nathan Karns, who they will control through the 2020 season. Earlier this offseason the Royals dealt closer Wade Davis -- who, like Dyson, can become a free agent at season’s end -- for right fielder Jorge Soler, who they will also control through 2020. In both moves, the Royals’ front office decided to aim for major league players instead of prospects with higher upside, since they still have a window to get back to the postseason.

The Royals still have several potential free agents to worry about after this season, including Eric Hosmer, Alcides Escobar, Michael Moustakas, Lorenzo Cain and Danny Duffy. However, this group is expected to stay until at least the July trade deadline -- unless someone overwhelms Royals GM Dayton Moore with an offer he can’t refuse.
