The problem in Potomac is that you have Hood in RF and Eury Perez in CF, neither of those two guys can be promoted and all three guys need to play everyday.
Meanwhile there's absolutely nobody in Harrisburg in the OF, so Bryce could continue to play in CF or RF without displacing someone.
I'd move him directly to AA and see how he adjusts to pitchers that can locate their breaking pitches and exploit his weaknesses in the zone (if he has any?!?).
