Tonight at 8pm EST, the deadline will pass for teams to lock in their 40-man rosters ahead of the Winter Meetings. Once the deadline passes, a team will not be able to add a player from within their organization to the 40-man roster until the end of spring training in 2018.
Players left off the 40-man roster and who are eligible, can be selected during the Rule V draft, which occurs on the 4th and final day of the Winter Meetings. This year, the draft will fall on Thursday, December 14th.
The Tampa Bay Rays currently have a 40-man roster consisting of 32 players, leaving them with eight spots to fill before the deadline and they have plenty of candidates to choose from.
