Murton had a .342 BABIP in the big leagues last year(his AA BABIP was an obscene .376 by my calculations, completely unsustainable). Only 7 players in each league were able to do that last year and qualify for a batting title, and they are some of the best hitters in the game, or at least ones with styles conducive to a high BABIP(Wily Taveras doing his Juan Pierre impersonation). It's completely unreasonable to expect Murton to duplicate that. Murton is here to stay, and I'm guessing his OPS will be more in the 850-900 range consistently. I really don't see him struggling enough to give Dusty a reason to keep him out of the lineup. Murton is the type of hitter that this team has been lacking for too long (a good one). Remember, he was drafted by the BoSox, not the Cubs. He's bound to be good.
