I don't think scouts are looking at those stats as much nowadays, it's all about the underlying metrics, exit velo, swing and miss% spin rate etc etc. His high whip is more of a function of walks, not giving up hard hits.
Perales is closer, but these guys are ranked #7 #9 in the Sox system, a system where 6 of those top 9 are on someones prospect list. Wilkeman may not be that far away, saying a guy is top 100 or close to top 100 are two different things. Perales likely gets there first, and has more of a chance of doing that. But aside from walks, GOnzalez has been great. A young arm struggling with control isn't exactly the most uncommon thing either.
Perales I think has a chance to break onto some lists this offseason if he finishes the year on trajectory, Wilkeman may need to continue this into next year and maybe get on some mid seasons.
It could go the other way too, they could fall off a cliff.
