I'm assuming it's Burger that goes down. You need MI insurance more until TA is back, and potential ABs for Burger dry up quickly with Eloy and Yo returning.
It's not like there's a slate of lefty starters coming up either, and even if there was, you're not putting Eloy in the field fresh off an IL stint to make room for Burger at DH.
The more interesting question will be what happens when TA comes back, and that maybe depends on how much run Sosa gets and what he does with it.
