If everyone on this team was healthy, then "Burger, Moncada, Eloy, Vaughn, Pollock, Abreu" are 6 guys for 5 positions (3b, LF, RF, 1b, DH). One of them sitting on the bench every day wouldn't be a bad setup, except for the fact that they're all Right Handed.
If no one has a major injury, then where do you find room for a lefty in the OF without permanently removing one of those guys from the lineup or sending Burger down to AAA?
