I think this is the biggest open question about the opening day roster. I thought previously you could fit Heyward on the roster along with everyone else at least until it went back down to 26. But now it sounds like the Cubs are going to do 15 pitchers/13 hitters to start the year. So, barring an injury, one of Heyard, Ortega, Hermosillo, or Frazier won't make the roster. Frazier is optionable, and so maybe it's as simple as that? The team under Jed has always waited as long as possible to make permanent moves.
