If Contreras must play, and it seems like he must, can't he be moved to like 5th or 6th at least? I know Murphy kind of likes a "second leadoff hitter" toward that sport but couldn't Contreras then act as a 2nd #2 hitter?
I don't know who I would rather give 2, 3, or 4 at bats to but I would think Frelick, Chourio, Yelich, Vaugh, Collins? Maybe that 1-5 when Vaughn is going to play? Collins could slide into #2 spot if Vaughn is going to be on the bench. I think Frelick and Chourio need the most at bats, with Yelich 3rd. Until Contreras starts at least putting together more competitive at bats (I understand his power is going to be limited with his hand) he doesn't need to see the 3rd or 4th most at bats on the team, IMO.
