Tyler Kepner has a great piece in the New York Times today on the Astros, which is definitely worth your time. Yes, Bo Porter "painfully" rewatched the entire 2013 season. No, the Astros aren't going to promote everyone at once.
And to that point, the Astros are going to send Carlos Correa to Lancaster to start the season, and "the team plans to promote him (to Corpus) after a month or so."
Might Mark Appel be on the same timeline?
