No. 9 is a consensus rank, not a Fever call. It's the weighted average of four outside shops — Baseball America, MLB Pipeline, FanGraphs, Keith Law — a place to start looking. What's ours is below: the read where the engine can see him, and nothing where it can't.
The Fever read
we can't — and we say soHe's at AA, below AAA. Exit velocities exist only where the ballparks are wired — AAA and the majors — so there is no EV95, no board, and no call here. That's not an omission; it's the honest edge of what the engine sees (ethos #6). We watch him for the day he reaches a level we can grade.
