We're stuck with him, of course, and he's young enough to improve, but I am feeling like Brandon Marsh has been a black hole in the lineup for a long time now. He has one home run since April and his OPS since April is in the mid-500s. He is really the worst hitter in the lineup (except when Harrison or Guthrie plays).
And I am not at all sold on his defense (though compared to the guys on either side of him, he's Garry Maddox).
As I said, we're stuck with him, and maybe he will improve eventually. But I'd bat him ninth for now, and I'd sit him against lefties.
