MLB's 2025 Rule 5 Draft happened on the afternoon of December 10 during the annual Winter Meetings. Players who signed with their club at 18 years old must be added to the 40-man roster within five seasons, and players who signed at 19 or later need to be added within four seasons to avoid becoming available to other clubs in the Rule 5 Draft.
It was an unsurprisingly busy event for the Boston Red Sox. They lost some prospects and gained a few more. There was a shock name taken and a handful of players who, surprisingly, stayed in the organization.
