I understand MLB The show 20 does not yet code for a player like Shohei Ohtani In franchise mode. That being said even when I slowly go though a sim (Playing/Fast playing) every game because there is no way to add him to the lineup in sim. He does not regenerate his stamina/energy when you DH him. This is DUMB because if you DH anyone else they regenerate their energy just fine as a DH; NOT Ohtani. Please fix this! This player is one of the best players in the game of baseball today and it seems sad to me that putting him in a franchise is more of a risk then a reward.
I did a MTO with Angels and he would DH on days the CPU set the lineup(due to starting players energy) on the days he was scheduled to pitch, he got rocked, he had an ERA over 7 for the year, it would not let me take him out of the rotation. My guess is that he never got enough rest.
