Prestige XP program

I've noticed a few new players were discovered in the past week: Finest Jose Ramirez, Eric Thames player of the month and postseason George Springer.

I thought these players were mistakenly released but it looks like in their locations they are acquired through the prestige XP program. Is this hidden? does anyone know more about this? other players to get, how to get them etc..

Its hidden. Its part of Prestige xp

It's a hidden xp path after you reach 99 diamond, it'll unlock once you reach there

I'm looking forward to that Prestige Diamond Larkin.
