I think that the bottom line is that it's clear if things don't turn around Hicks doesn't belong in the majors right now. Having him way over his head is not working through struggles, it builds frustration, leads to a lack of confidence, and ruins good mechanics as hitters make flailing adjustments (see Dozier last year). Second, whether or not you think this team can compete, saying no one else can help them win games just isn't true. Hicks is one of the two worst hitters in baseball through these first three series, if not the worst, and he's posted the most negative WAR so far. So by almost any standards, any ML CF including Mastroianni, would be able to help the team more. I agree that that may not be the concern if Hicks were just "struggling," as the team just isn't that good, but this is far more than that.
