We aren't rushing him. He has totally owned that level and it's not a small sample size either.
He has played 51 games and has a WRC+ of 148 with an absurd walk rate of close to 20%. He isn't being challenged there by the pitching.
Move him up to High A.
Braden should also be promoted to AA at some point in the very near future. Just get that BA up a bit and improve contact and get the K rate back down under 20%. It shouldnt be too long with Braden if he can keep hitting well and with power and keeping Ks in relative check, maybe a few more weeks.
Zavala should also hopefully see some substantial time in AA this year too if he can keep hitting well at the plate as he has done recently.
