He was able to repeat levels once in his rapid ascent through the minors and his BB/9 went from 4.2 down to 1.9. And control is a trait that is very commonly improved upon.

As for the size and velocity "warts" that has been addressed countless times on this forum by myself and others, Peralta has off the scales extension which makes his low 90's fastball get on to hitters like that of a mid 90's fastball. He hides the ball well and he's also 22 so there's a definite window to add a few ticks to that fastball which already was being clocked at 94-95 on occasion at the end of this season.

It's obvious at this point that many here are just going to have see it for themselves before it's proven what this kid is capable of. I'm very much looking forward to that time.

I've addressed this many times. The change he's working on would be the equivalent of a 4th pitch. When you throw two different acting fastballs in near equal doses and mix in a curve that's your 3 pitches. He's shown in the majors the ability to go through a lineup 3 times. In fact his numbers improved the deeper he went. He's such a misunderstood prospect because (and I'll repeat myself again) people fail to understand what his absurd extension adds to his velocity. When you watch it overhead in slow-mo it doesn't even look human. Throw out his height because his release point is that of pitchers half a foot taller. His 4 seam cutter is his low 90s fastball with a spin rate among MLB leaders. That's the one with the ridiculous movement. His traditional 4 seamer has rising action and has started to top out in the mid 90's at 22 years old. The extreme extension adds a measured 2+mph equivalent to the batter so 90 becomes 92 and 95 becomes 97. At some point people are going to have to start remembering these things. I don't say that directly to you or in any negative way. It's very clear that people are going off basic measureables but for some reason completely ignoring his statistical profile. He unlike Woodruff has had tremendous numbers multiple times through. And his BAA was near the league lead as well. He was up there with Snell, Sale, and Scherzer. He is an absolute anomaly. Which is why he's so misunderstood and undervalued no doubt. Thankfully the Brewers know what they have.
