It shouldn’t. Tauchman has been ass since April. He has competitive ABs but the results are meh. For the season about the same as Busch, and he was much worse than Busch in May even with Busch struggling himself.
Busch’s defense has also improved tremendously (up to +3 OAA). I think I’d want Cody in RF and Seiya DHing a good amount of the time. Tauch can PH for Busch when more contact/OBP is needed, and then slide Cody to 1B.
