During the postseason, pitchers enter with 75% stamina. This has been an issue all year. They haven't responded to my bug reports (shocker). So I found a workaround, if I go to Quick Manage and switch pitchers, they'll have full stamina. However, now when you go to QM it makes the game go haywire and essentially resets. The game has no memory of what happened previous. I got Albies and Acuna out, subbed a pitcher and they pinch hit Albies and Acuna. Just laughable at this point.
