Moncada plus Grandal and Pollock getting on track should help there. Vaughn before injury was also hitting righties well.
I think if you can get everyone back consistently they'll start hitting righties much better. We'll see if that's enough for top tier right handed starters in the post season.
You over-rely on those guys when 1/3 - 1/2 of your lineup can't produce. You can also pitch around those guys, and when they're already aggressive and already trying to do too much...
Too many black holes right now. Mendick, Leury, Sheets, Burger, Harrison and McGuire taking up 3-5 lineup spots every day. Get Moncada and Vaughn back and you're back to hopefully only 1 bad hitter per day.
