I don't think there's a whole lot of rounding into form that's going to happen. He's gonna get hot, and he's gonna get cold. He's a perfectly average hitter, but the right-handed power is useful to us.Not a benching per se, but no need to run him out there every day once Verdugo comes back. Let him round back into form more gradually.
Since he's got the slightest platoon split for his career, obvious thing to do is to play him against LHP and the occasional right-hander when someone really needs a day off. Duran, Verdugo, and Yoshida all crush right-handed pitching, but both Verdugo and Duran have pronounced splits, so I would hope they would give Refsnyder and Duvall the platoon side of those matchups wherever they can.
I suspect Duvall is going to get some "veteran" playing time, though. We'll see, I guess.
