BA's 2016 handbook has his changeup as his other offspeed, lagging behind the curve. I vaguely remember in 2013 that his changeup was his best offspeed out of HS, can't find a link, but he was drafted based on his size, arm strength, arm speed, athleticism, and high level of conditioning anyway rather than offspeeds. Even as a pro his fitness stands out enough that it ate up maybe a quarter of BA's 2016 handbook writeup - they say he's up to 215 by adding "strength and definition to his now well-toned frame." I'm too lazy to link but various articles have a peak velocity of 97. This is one of my preferred prospects in the system. I have been comparing him to Underwood for some time now thanks to having the same ARLs, and he's consistently been the better performer. I don't buy him as a starter but there is no need to get caught up in that for a healthy, effective arm in High A. The shaky nature of his secondary pitches before this season, I don't know how much they've improved, and his funky delivery could have his future in the pen, but so far so good with Clifton. I know you were much higher on Kellogg than Clifton before. Has that changed?
