We’ll use this post to keep track of the players being added to their teams’ respective 40-man rosters today, which is the deadline to protect players from the Rule 5 draft. Players must be added to the big league roster within either four years (if they were 19 or older at the time of their original signing) or five years (if 18 or younger) of their signing year in order to be shielded from selection.

MLB.com’s Jonathan Mayo took a look at some of the biggest names who face roster decisions, though most of those won’t be much in question. At the fringes, teams must also consider the major league readiness of the player, since that factors heavily into whether they’ll be taken and kept. Any drafting team, of course, must keep a player on its active MLB roster for the full season (with certain exceptions relating to the DL) in order for their control rights to vest. Adding a player to the 40-man too early can have its own risks, because it limits flexibility and could require a team to expose that player to waivers if a need arises. With 26-man rosters reportedly under consideration, the Rule 5 draft could be quite intriguing this year, and that may bleed into today’s decisions as well.

Below is a division-by-division rundown of the names that were added to each team’s 40-man roster (plus the various waiver claims that spawned from teams trying to outright players to protect Rule 5-eligible prospects). We won’t delve into each player’s background, but if you’re looking to a little more about the names that were added, I’d highly recommend this tremendous, in-depth examination of each team’s additions by Baseball America’s J.J. Cooper. If you want to see how the moves look in the context of a team’s roster, head over to Roster Resource for your club’s depth chart.
