Colas is batting .100 vs lefties this year. Sheets and Haseley should never be in vs lefties. So yeah. Maybe play Colas and get some experience but yes, these are the bodies he has.
Andrus, to his credit, has a .375 OBP vs Lefites this year in 24 PAs. Not a big sample size but at this point, may as well be 1.000 for what we are dealing with.
There is no making a good line-up here.
