Kemp has more PAs, but less games than Rojas did when he won it in 2023. Crawford won last year, so it felt unlikely he would win again given his year was great, but not so good you had to give it to him. Same thing with my preferred pitcher Jean Cabrera who was a really workhorse, but won in 21.
On the Castellano thing, I think they want to see if the stuff bounces back further from injury so they can protect or trade him. I suspect he wouldn’t cone back in straight FA, but that is a guess.
They have struggled with getting AAAA starters to sign because of the MLB depth, maybe an open competition with Wheeler delayed brings guys in, but they have had to do more waivers and small trades for AAAA depth
