I hope the players union pushes hard for the DH in all leagues if they intend to strike before 2020. The current CBA expires after the 2021 season, and this issue of platooning a 1B wouldn't exist. With the DH and a 26 man roster, an extra utility hitter could be utilized to play the hot hand. Zim would be the starting 1B or DH depending on if he needed a day off, and Adams could be the opposite for RH opponents and lefty opponents would have to face the other utility guy, preferably right hitting.
