With MLB Opening Day a week away, certain top prospects might not crack their team’s rosters, but that doesn't mean they'll be far away.

Alternate training sites are back for the start of the 2021 season after Major League Baseball informed teams that the Triple-A season would be delayed by a month. This year’s version of the sites will be similar to those used during the pandemic-shortened campaign a year ago. Players not on their teams’ Opening Day rosters will train and practice at locations near their clubs’ big league ballparks.

The move removes the obstacle of commercial travel for Triple-A players and those called up to the Majors for the first month of the 2021 big league season as well as eases MLB teams’ task of coronavirus testing and protocol oversight. The Triple-A delay also affords players a likelier opportunity to be vaccinated before the start of the season.

All Minor League seasons are now scheduled to start the first week of May.
