Joshua Palacios has been quietly having a pretty decent season in AA. Just turned 24 less than a month ago.
121 wRC+
Career high walk rate at 12.8%
K rate unchanged between A+ and AA, 21.3%
Identical power - ISO .121 this season compared to .126 in Dunedin
13 steals, 15 last year
The only thing that might be telling is he's split his games between CF and the corners this year as opposed to last year when he was mainly a CF'er. As far as development goes though, he has basically performed as well in AA as he has a year after being in A+ so that's a big win.
