A K rate of 13.17 (per 27) isn't decent, it's outstanding.
SSS but they're babying him right now in terms of pitch count. RP in college so you can't push too fast.
He'll be 22 in June, so he's not a 18 year old arm you want to protect for a couple years.
I'm sure they're working on mechanics right now, and see if they can teach him a changeup (FB/slider combo).
He'll start to get IP, but if he doesn't add the 3rd pitch will soon be a full time RP.
