The Royals made their first post-Opening Day roster move Thursday by demoting Dylan Coleman to AAA Omaha. Coleman was an excellent reliever in a beleaguered bullpen last season, posting a 2.78 ERA and acting as a setup man by season’s end. This season has been very different for him. In the team’s first 12 games he made five appearances and while walks have always been an issue for him, he has already walked seven to start the year. He hasn’t been able to limit the damage there, either, as he’s given up a total of 10 runs. The kicker came on Monday when he walked four and allowed six runs in a game the Royals were still in before he took the mound.
