"I think it is just normal for a middle reliever," Coleman said. "There are no guarantees."
Coleman, 28, has had a respectable spring, posting a 3.55 ERA in nine games entering Wednesday's Cactus League game against the Dodgers.
"He has been OK," manager Ned Yost said. "He came in with a lot of competition. He's held his own."
Coleman even has what might be construed as an edge -- he is out of options and the organization may not want to risk losing him if he is designated for assignment.
"It can help if you have a good spring," Coleman said. "But if you have a bad spring it won't."
About all Coleman, now in his seventh season with the Royals, knows for sure is he would love to stay with the organization.
"I love it here," he said.
