Why is Uncle Mike Playing so little in the field so far this season?

Has anyone else noticed how little Brantley is playing in the field this year? Nothing against Yordan, but Uncle Mike is a much better defensive Left Fielder. Does he have a nagging injury that they are wanting to make sure doesn't turn into something bigger (Like Bregman last year)? Just seems a bit odd to me and would love to know if anyone has any insight to what's going on there.
