As of now we still don't know exactly what a 2020 season will look like. But either way, I think we'll see some surprising prospects make debuts with the Atlanta Braves.
We already know rosters will be expanded in a shortened season, likely to 30 players.
What we don't know is how the Minor Leagues will be handled. Most likely, we will not have a Minor League season in 2020.
But, I still think we will get some sort of extended spring training for Minor League players where they'll stay in shape and workout with the team.
