Aaron has been adopted for a second season by yours truly. The lazy approach is being taken at the outset, by a bit of cut-and-paste from last year's post.
The Twins signed him in 2013 after a three-year career at Indiana University, where he won Big Ten Conference Baseball Pitcher of the Year honors in 2013, putting him in good company with Tyler Jay (UI 2015), Alex Wimmers (OSU 2009-10), and Glen Perkins (UM 2004).
After an initial season in Elizabethton he has moved up in the organization with pretty good speed, seeing time in both Cedar Rapids (A) and Ft Myers (A+) in 2014, Ft Myers and Chattanooga in 2015, and then Chattanooga again in 2016. 2017 was a solid year in Rochester, earning a mid-August callup to the majors for a spot start and then was added again in September. You can look up his numbers at the above link better than I can repeat them. He has done well at every stop - never consistently dominant, but always a workhorse getting the job done. Once in a while he has shut-down stuff, as witnessed by a short-game no-hitter in his first start last April. Aside from his get-the-feet-wet time in Rookie ball, he has always been used strictly as a starting pitcher.
He has a good fastball - I saw 94 on the radar gun during the one Spring game of his I watched, or 91 at times (maybe a sinker?). Off-speed at 86 but I don't know if he has anything really slow in his arsenal. He got a very nice "failed checked swing" for a strike 3 on one batter, and in the next inning I saw another called 3rd strike for a 3rd out. I have no idea if those were changeups or sliders. But those batters at least were not able to get a good read on his delivery - if it were the changeup it would be sweet - good two-strike changeups are always sweet, at least except if the batter is sitting on it.
I don't personally believe too much in slotting starting pitching prospects' ceilings as #5, #4, or whatever, but in those terms I do see Aaron as having a ceiling more like a #3 workhorse, and it's not impossible that in a few years he'd fill a #2 role in some rotation, maybe even ours. But right now he is fighting simply for a 25-man roster spot and would slot in as a #5-type if he is so fortunate, and he surely has a lot more work to do to learn the final tricks of the trade that let a pitcher succeed at the highest level.
