We are a little more than a week into September call ups. The Diamondbacks have brought up mostly pitchers, as expected; however, this week they have started to shuttle some more fielders to the big club. As minor league teams finish their seasons, the Diamondbacks will have an opportunity to add more players to the big league roster. Whether they do or not remains to be seen. There is such a problem as having too many players.
In order to share scarce playing time with an increasing number of players, the Diamondbacks need to consider whether they are making a playoff run, the development of their established big leaguers, injuries, the minor league playoffs, service time, 40-man roster status, and whether or not being in the show would be a benefit for a player.
