With just one series left in the regular season, the Red Sox have their roster mostly set depending on health. There are a lot of keys for their success in the postseason, but one could argue that the most important part of their roster is their bullpen. This has been the key to their success all year as the consistent performance of the relief corps has helped lead to all of the extra-inning wins and all of the late-game comebacks. Without those late victories, there’s no way this team would be atop the division right now. For as good as the unit has been, though, the roles beyond the closer have been fairly fluid all year.
