The Red Sox started the season with 25 players. Here's the list of players who have been active for all 107 games:
Every other player the team who has been on the roster this season (38 all told) has either spent time in the minors, with another team, on the disabled list or on the bereavement/family leave list.
Imagine that, 48 players. I wonder if Terry Francona could name them all if he had to?
I tried and forgot Fabio Castro and Alan Embree, who were on the roster but never got in games.
