As the Orioles traded their veteran players earlier in the season, they received a number of players to be named later (PTBNL) in those deals. They had one coming from the Marlins for Richard Bleier, one from the Rockies for Mychal Givens, one from the Mets for Miguel Castro, and two from the Braves for Tommy Milone. Over the past week, the O’s had three of those five players named. All three were international amateur signings in either 2018 or 2019.
The 2020-specific rules for trades that MLB established meant that there were more of these PTBNL being swapped around than usual, as teams were only allowed to make trades of players who were in their 60-man player pool.
