Manager Dave Roberts called the decision to send Baez down difficult, adding that while Baez took the news like a professional, he was also upset. Roberts called the move necessary because he wanted to make sure Los Angeles had enough long relievers on the roster with the 21-year-old Ferguson and 22-year-old rookie Dennis Santana scheduled to pitch on Wednesday and Thursday.
