I agree that flipping Harper and Hoskins would be smart, but in past years sharpers OBP has been much higher so we might be making a decision based on an extended slump that Harper had.
Sadly we really don’t have a better #5 hitter. Hernandez might be an option since he does get singles and does work counts. Kingery might be a better option if Hernandez could get his OBP up again and move into the lead off spot.
Maybe we will pick up a rental CF or more likely 3B that could provide some production. Realmuto is miscast in his present spot in the lineup, but someone has to hit there.
If you want to do something really radical have Hoskins leadoff, then Kingery, Harper, Franco, Segura, Realmuto, Hernandez, Pitcher, Quinn/Haseley/Williams. That would get your best hitters more PA’s
