Very good read by Don on players that could be potentially taken in the Rule 5 from the Orioles system.
He provides a quick report on each player listed.
There are plenty of places where you can find the specification of the Rule 5 process. The basic outline of the plan was intended for players to find additional avenues to reach the majors, when a team limits the chances of a player making the parent club. There are three basic principles that make minor league players subjected to this process.
Major League Phase:
1. The minor league player is left unprotected off the the 40 man roster as of November 20th when the roster has to be submitted to the Major league front office.
2. Left unprotected and 4 years of MilB service at age 19 or older. This is typically JC and 4 year college drafted players.
3. Left unprotected and 5 years of MilB service at age 16-18 years. These are typically international free agents and drafted high school seniors.
Minor League Phase:
In addition to the qualification rules of the major league phase, teams can protect 38 players on their AAA roster and 37 players AA.
All teams do a solid job identifying their best prospects and stash away the top 75 players. Usually, it is pitching that is selected at the AAA and AA phases to help with depth.
Below is a list of the higher profile minor league Orioles that could be subjected to their 1st waiver process, if not protected by the Orioles on the 40 man roster before November 20th. I think all fit within the top 75 prospects and should not be subjected to the AAA or AA phase, but stranger things have happened.
