Tuesday marks National Reserve List Day in Major League Baseball, a critical deadline for teams like the Texas Rangers to decide which minor leaguers to protect on their 40-man roster. Players signed at 18 or younger must be added within five seasons, or they risk exposure in the Rule 5 draft.

The Rangers have lost pitchers in recent drafts and are keen to avoid that fate again. They have several promising prospects, including Emiliano Teodo and Winston Santos, who are likely to be added to the roster.
