I'd move Soto to AA to challenge him. Of course, I'd also move Francisco to catcher (or, if he's unwilling and/or defensively challenged, RF). Soto is, IMO, the best prospect in the Cincinnati pipeline by a wide, wide margin.
He's hit well and he's young for his league. Not only that, he's also hitting with power. The walks will come as the rest of the league begins to fear him.
