The bottom of your lineup (Wyrth, Weiters, Taylor, pitcher) bailed us out in those games. How many times did they kill the momentum and leave people on base in those games. alot.
The top and middle of the lineup did virtually nothing the first four games. Harper and Murphy both had two hits in four games. And I believe the same for Rendon. Turner had one hit. That's what killed them. And you know the Cubs pitching is not great. Good luck against the Dodgers lineup as you will need it.
