Courtesy of Reddit, user mat2019 has compiled all the revealed cards so far and how to get them in MLB The Show 20. This is a very preliminary list as it’s just based on all the streams, but for those who are starting to plan out their Diamond Dynasty teams and how they want to start grinding, this Google Sheets might be helpful for you.
We have done our best to track these cards via our own stories, but it’s nice to get them all in one spot. The stream over the weekend was a huge content drop, so aggregating all of the new players was necessary. We are also very close to release of MLB The Show 20, in fact the “early release” kicks off at midnight on 3/13.
