Yermin Mercedes wrote in an Instagram post on Wednesday night that he is "stepping aside" from baseball indefinitely while also apologizing to the Chicago White Sox for not "accepting some of their decisions."
The post was accompanied with a picture of the words "it's over."
"I want to apologize to all those who I inadvertently offended as a consequence of my immaturity like members of the radio, television, and press," Mercedes wrote in his post. "To all the team's members where I was involved with, I'm sorry for failing as a human being and for not accepting some of their decisions. I'm stepping aside from baseball indefinitely."
It's unclear what decisions Mercedes was referencing in his post.
Mercedes, 28, hit .415 with five homers and 16 RBIs in 22 games in April, but he struggled after that. His batting average dropped to .271 before he was demoted to Triple-A Charlotte at the beginning of July.
