At bats are just a piece of it. It’s overall playing time, which using the DH slot as a partial day of a position player would do.
And it’s the roster spot. There going to carry 13 position players. 2 catchers. An OF of Meadows, Greene, Baddoo, Carpenter (all LHHs) and Vierling, 5 OFs. A probable starting IF of Torkleson, Schoop, Baez, and Maton. There’s going to need to be a backup IF, so that’ll be a 5th IF. So that’s 12 position players right there. Cabrera is the 13th. That doesn’t leave a lot of room for platooning, which the projected LHH heavy OF would need. They could use Haase in the OF, but they likely won’t be able to do that against all LHPs.
Then they run into issues like they did last season where, because of poor roster construction, they can’t make moves late in the game to PH, PR, or have a defensive replacement. Or someone gets dinged with a day-to-day injury which shortens the bench.
