This roster move came right after the demotion of outfielder Terrence Gore. With Strahm going down also, this very likely means at least one reliever is coming up for the KC Royals.
Some options for the bullpen may include Scott Alexander, Kevin McCarthy, Jake Junis, and Al (insert city in New Mexico that I don’t want to spell). Possible outfielders may include Whit Merrifield or Billy Burns, while a DL move with Jorge Soler is still possible.
The Royals have had no issue with sending high expectation players down due to lack of performance. They sent down Mike Moustakas after an early season swoon in 2014.
