I would guess the lineup looks like this as of right now:
1. Anderson SS
2. Benintendi LF
3. Robert CF
4. Eloy DH
5. Moncada 3B
6. Vaughn 1B
7. Grandal C
8. Sheets (or/and then after 3 weeks, Colas) RF
9. Romy
I wanted to put Vaughn in from of Moncada here but figured you probably need to break up the righties (Robert, Eloy, Vaughn) and lefties (Moncada, Grandal, Colas). Also didn't want to pencil in Moncada in the #2 spot as, to me anyway, he has to earn his way up. I put him 5th kind of by default but you're right, if we don't add another left-handed bat and Moncada and Grandal don't bounce back, it gets scary.
