When the history of the 2016 season is written, Friday, May 27 will likely be seen as a day of significance. Let's review, and also peer into the future.
I don't recall any other day, perhaps excluding mass call-ups once rosters expand in September, where Arizona made eight roster moves. We saw 40% of the rotation hit the disabled list, concurrently with one-quarter of the bullpen being sent to the minors. In return, we got three relievers - two are likely short-term moves, to provide arms out of the bullpen until the starters' spots come up on Sunday and Monday - and a position player.
