One of baseball's more intriguing divisions heading into September, the National League East boasts a pair of teams with clear designs on a division title, a third club that could still muster a late postseason run and two others gearing up for 2019.
For all of the teams, the game is about to change. With rosters set to expand on Saturday, teams can carry up to 40 players on their active roster. While few clubs go quite to that extreme, the list of September callups who have influenced pennant races around baseball -- Francisco Rodriguez, David Price, et al -- is long and growing longer.
