Just discovered the Seedlings To Stars site, and it looks pretty kewl at first glance.  

I'm always a bit taken aback to see a national site write up a local prospect and sound pretty much like the locals would on that kid.  As mentioned, Seedlings to Stars isn't based in Seattle as far as I know, but they've ranked Jose Campos #82 in baseball.  Campos is the only Northwest Leaguer to make their top 100.  Like we said, they must be completely brilliant, eh.

....

I don't think there is any question that Paxton, Taijuan, and Danny Hultzen rank even higher than Campos does, whether you are talking about (1) upside or (2) probability of ML success.  

As the 80'ish, 90'ish rankings for Campos roll in this winter, it will become ever more obvious that the Big Four SP's are four of the minor leagues' top 100 commodities -- which is to say, that the M's have four of the top 50 pitchers in the minors.  

And that doesn't include Michael Pineda, who if he paradigm'ed out as a prospect, would be #1 in baseball.

A bit of kibitz'ing on S2S' fine article:

Why He’s This High: .... performance in short-season leagues alone isn’t going to get a player on a top 100 list; he has to have upside beyond that, and Campos does. He’s got a bigtime fastball, coming in at 91-93 mph with heavy action on it, and his projectable frame should allow him to gain more velocity. He already does an excellent job spotting the pitch, as evidenced by his superb performance.

We knew that, but S2S is a national site, so you gotta like the fact that they put their finger on the right spot here.

Every 18-year-old's frame projects for him to add velocity.  That's the default assumption.  Sometimes an 18-year-old won't gain velo, but usually he will.  You pencil Campos in for Max Scherzer velocity, at least, when he's 21.

.

Campos already complements the fastball with a solid slider, and while he needs to develop a third pitch, he’s so young that he has plenty of time to figure that out.

Mechanically, Campos is quite smooth, and there aren’t any major red flags in his motion. With his size and easy delivery, he projects to handle a big workload in the big leagues.

As you know, Dr. D preaches the heresy that for many young pitchers, the third pitch can actually be counterproductive.

It's quick and easy for a pitcher to get a feel for sequences and locations when he's only worrying about one offspeed pitch.  ... Then, after that pitcher spends two years beating major leaguers, he can add the change in year 3 -- as CC Sabathia did, for example, and as Michael Pineda probably will in 2013.

Jose Campos needs to be fast-tracked.  A pitcher only has so many bullets in the gun.  If he's throwing great now, get him in there, as early as feasible.  The way to do that is with two pitches.

.

More in the long term, he’ll need to develop a changeup, and both his fastball and slider will need to take a step forward if he’s going to project as a front-of-the-rotation guy. It’s reasonable to expect that those improvements could all occur

In the comments, somebody graded his fastball as 50 (exactly ML average).  :- )  Campos' fastball is reported to have plus velocity, plus-plus location and plus movement.  He's missing bats, tons of them, just throwing fastballs to spots.   There are any number of guys who don't miss bats with 95 fastballs, including in the lower minors.

Right now, SSI gingerly slides Campos into the Bartolo Colon / Curt Schilling family of pitchers.  It's questionable how good his offspeed stuff needs to be, or even if he needs one.  But if he is throwing a strikeout offspeed pitch then he'll whup A+/AA right Now.

.

Since he’s so raw and unproven, I’m being conservative with this ranking and not pushing him even higher, but Campos is a pitcher who could put himself in the top 50 conversation just by sustaining his performance next year in Low-A and staying healthy. 

Right now, Campos is what Pineda was at 19, except even a little farther along than Pineda was.

There's only so much you can ask from a teenage pitcher who has a boy's shoulder structure, but Campos is doing algebra in 3rd grade.  He's top 100 if any teenage pitcher is top 100.
