Along with Opening Day for the Red Sox taking place on April 7, less than two weeks from today, the minor-league season will also be getting going for the four full-season levels that week as well. With that in mind, this week we will be previewing those four levels for Boston, using the projected rosters from our friends at Sox Prospects. For each projected roster we’ll cover the top prospects for position players, starters, and relievers, as well as a sleeper and other notables from the roster. Today we kick things off with Low-A Salem.
