Snow was optioned to minor-league camp Friday, Maureen Mullen of MLB.com reports.
The career minor leaguer was perfect through his first two spring appearances before getting touched up by the Red Sox for five earned runs on four hits -- including a pair of home runs -- over one inning Tuesday. Snow is slated to provide organizational depth in the coming season at Triple-A Durham, as he's yet to make a regular-season major-league appearance in a professional career that dates back to 2010.
