I don't view Yelich as an elite defender anymore. In fact, he is probably the weakest defender out of Chourio, Frelick, Wiemer, Mitchell and Taylor. Just another reason not to have him in LF when we have a lot better options defensively.
He's either destined for 1B or DH, playing him in the OF doesn't seem to be the best thing for the team any longer. (Yes, I know Arnold said he wouldn't be playing 1B)
