Here's the press release from MLB:
Cleveland Indians pitcher Carlos Carrasco has received an eight-game suspension and an undisclosed fine for intentionally throwing at and hitting Kevin Youkilis of the New York Yankees in the top of the fourth inning of the Tuesday, April 9th game at Progressive Field in Cleveland. Joe Garagiola, Jr., Senior Vice President of Standards and On-Field Operations for Major League Baseball, made the announcement.
Unless appealed, Carrasco is scheduled to begin serving his suspension during Cleveland’s home game tonight against the Chicago White Sox. If Carrasco elects to file an appeal, then the discipline issued to him will be held in abeyance until the process is complete.
