Coleman made the Royals' Opening Day roster, Anne Rogers of MLB.com reports.
The 25-year-old right-hander got his first taste of major-league action last season, allowing one run on five hits and a walk with seven strikeouts in 6.1 innings. Coleman made the Opening Day roster because fellow reliever Joel Payamps (personal) was placed on the family medical emergency list. As such, Coleman will need to hit the ground running if he's to retain a spot in the big-league bullpen. He was solid with a 3.55 ERA, 1.09 WHIP and 56:17 K:BB while logging a 4-0 record and three saves with Triple-A Omaha in the latter half of last season.
