On July 2, San Diego Studios kicked off the 4th Inning Program for MLB The Show 21. This program includes several big rewards, including two Kitchen Sink Choice packs, a Boss Choice pack featuring three 99 OVR cards, and a 90+ OVR Live Series pack. To make the grind a little bit easier, SDS released a new Player program for the 4th Inning Program on July 9. A new 95 OVR Milestone Billy Williams is up for grabs, as MLB The Show players can not only pick up a card than can be used towards the Mariano Rivera collection, but also receive 35,000 XP upon completing the program.
