It took only three games for us to be able to refer to Trevor Story as a rookie sensation. For the most part, this is because Story is currently out-homering most of the teams in major-league baseball. He got Zack Greinke twice on opening day, and that’s remarkable enough, but Story homered again in each of the following two contests, so now here we are, with Story owning four dingers before the overwhelming majority of rookie players are even called up so as to preserve that extra year of control. Hot start. We’re good at noticing hot starts.

After the hot start will come a cooler period. In time, when we have more information, Story will resemble some kind of familiar shortstop, and we’ll have a better idea of how he’s going to work out. In the long run, I mean. The reality is we don’t know that much more now than we did a week ago. This is the hazard of trying to talk about anything so early in a season, and so early in a career. But the word “irresponsibly” is right in that headline. I think we can allow ourselves to have some fun. What’s the downside? So let’s discuss just a few notable observations. Exactly what they mean, I’ll leave to time to settle.

I can’t tell you whether Trevor Story is going to be a good major-league ballplayer. I can tell you with a high degree of certainty he’s going to be some kind of major-league ballplayer, but as for how he fares, well, that’s more unknown. He has the skills to make All-Star Games, but the same could be said of plenty of non-All-Stars, and this’ll be a big year for Story’s career. He might build upon last year’s gains, and become a part of a core. Alternatively, he wouldn’t be the first young player to stagnate or regress.

Story has become a something on account of his spring, and on account of what’s going on with Jose Reyes. Reyes might never play for the Rockies again, so there’s a vacancy at short, and Story might seize it. Some want for Story to be named the opening-day starter, and there are the usual arguments in favor of waiting at least a couple weeks. No matter — by May or June, it seems like Story is going to be the guy. I can’t tell you if he’s going to be productive. I can tell you only how he’s interesting.

Any opportunity to talk about Coors Field is a good opportunity, and, hey, wouldn’t you know it, but the Rockies’ home ballpark is undergoing some alterations that’ll have an effect on the gameplay. I’ve only just heard about them, but they’re relatively uncomplicated, and they should be in place in time for the start of the regular season. Baseball’s best argument against the idea that high-scoring baseball is exciting baseball is about to feature some higher fences.

I’m kind of a dork about park effects, and that’s why I find Coors so fascinating in the first place. They’re always trying to figure out if it’s possible to play some sort of normal baseball at altitude, and now we can get into the latest thought, as provided by Nick Groke. The Rockies are working to reduce the number of cheap dingers. It won’t not work. That much we can already say.

Pitchers know hitters. They’ve got to. Sure, for the most part, pitchers want to trust their stuff and hit their spots and any deviation too far from one’s comfort zone is a concession to the hitter, but pitchers have got to know hitters, lest they be made to look silly. Example: pitcher faces high-ball hitter, throws high ball, gives up dinger. Well, duh. We told you he was a high-ball hitter, dumb-dumb. Why’d you put it there?

This is why pitchers read scouting reports, and watch videos, and look at heatmaps, and converse with their peers, and use their human brain to rethink past matchups against whichever opponent looms next on the docket. So they don’t look like a dumb-dumb. That’s all anyone’s trying to do, really. Competitive edge, work ethic, drive, determination — those are all just codewords for “Please don’t let my peers judge me.”

That’s why Mike Trout stopped getting the low fastball last year. It wasn’t for baseball reasons. It was so that anytime a nearby group of people shared a laugh over This Week’s Meme, the group’s laughter would no longer be misconstrued by the dumb-dumb pitcher who threw Mike Trout a low fastball as a public and personal lampooning.

But it turns out nobody is perfect, and that’s why we’re all insecure. Mistakes are made, constantly, by every kind of person at every kind of job. Making mistakes is one of the things humans are best at. All we can do is try to be better at learning from mistakes than we are at making them, and oftentimes it feels like an uphill climb.

Say, speaking of which, plenty of pitchers made mistakes to Nolan Arenado last year. Did you know he hit 42 homers? Don’t believe me? Look, here they are!

Now we have something different to talk about. Now we have something different we have to talk about. You’ll notice I’ve drawn a red line that splits the field in two, and you’ll notice that 40 of the black dots representing home runs are to the left of that dividing red line. You could say Nolan Arenado has a type.

You smell that? It’s baseball’s prospect-list season. The fresh top-100 lists — populated by new names as well as old ones — seem to be popping up each day. With the individual rankings coming out, some organization rankings are becoming available, as well. I have always regarded the organizational rankings as subjective — and, as a result, not 100% useful. Utilizing the methodology I introduced in my article on prospect evaluation from this year’s Hardball Times Annual, however, it’s possible to calculate a total value for every team’s farm system and remove the biases of subjectivity. In what follows, I’ve used that same process to rank all 30 of baseball’s farm systems by the surplus WAR they should generate.

I provide a detailed explanation of my methodology in the Annual article. To summarize it briefly, however, what I’ve done is to identify WAR equivalencies for the scouting grades produced by Baseball America in their annual Prospect Handbook. The grade-to-WAR conversion appears as follows.

Prospect Grade to WAR Conversion

Prospect Grade	Total WAR	Surplus WAR
80	25.0	18.5
75	18.0	13.0
70	11.0	9.0
65	8.5	6.0
60	4.7	3.0
55	2.5	1.5
50	1.1	0.5
45	0.4	0.0

To create the overall totals for this post, I used each team’s top-30 rankings per the most recent edition of Baseball America’ Prospect Handbook. Also accounting for those trades which have occurred since the BA rankings were locked down, I counted the number of 50 or higher-graded prospects (i.e. the sort which provide surplus value) in each system. The results follows.

Previous editions: Baltimore / Boston / Chicago AL / Chicago NL / Cincinnati  / Cleveland.

Earlier this week, lead prospect analyst Dan Farnsworth published his excellently in-depth prospect list for the Colorado Rockies. In this companion piece, I look at that same Colorado farm system through the lens of my recently refined KATOH projection system. There’s way more to prospect evaluation than just the stats, so if you haven’t already, I highly recommend you read Dan’s piece in addition to this one. KATOH has no idea how hard a pitcher throws, how good a hitter’s bat speed is, or what a player’s makeup is like. So it’s liable to miss big on players whose tools don’t line up with their performances. However, when paired with more scouting-based analyses, KATOH’s objectivity can be useful in identifying talented players who might be overlooked by the industry consensus or highly-touted prospects who might be over-hyped.

Below, I’ve grouped prospects into three groups: those who are forecast for two or more wins through their first six major-league seasons, those who receive a projection between 1.0 and 2.0 WAR though their first six seasons, and then any residual players who received Future Value (FV) grades of 45 or higher from Dan. Note that I generated forecasts only for players who accrued at least 200 plate appearances or batters faced last season. Also note that the projections for players over a relatively small sample are less reliable, especially when those samples came in the low minors.

1. Trevor Story, SS (Profile)

KATOH Projection: 7.2 WAR
Dan’s Grade: 50 FV

Story’s prospect trajectory resembles a bathtub curve — which is to say it’s gone from high to low and back to high again. Drafted 45th overall back in 2011, he got off to a strong start in the low minors, but hit a wall as soon as he reached High-A. Story got back on track in 2015 when he hit .279/.350/.514 between Double-A and Triple-A with 20 homers and 22 steals. Story was one of the top offensive performers in the high minors last year, which is mighty impressive for a shortstop. His 25% strikeout rate is cause for concern, but is largely outweighed by everything else he does well.

Other clubs: Braves, Cubs, Diamondbacks, Indians, Orioles, Reds, Red Sox, White Sox.

The Rockies’ system is a long list of potential major league contributors, topped by nearly a full team of 50+ overall grade prospects. They haven’t had the best luck developing young pitchers, but Jeff Hoffman and Jon Gray give them a chance at building a cost-effective pitching staff in the near future as they try to retool, while a stable of younger hurlers may arrive in three to four years. I don’t see any huge surprises on this list for people, though having Brendan Rodgers number one may be debatable. Gray gets bumped down a bit for command concerns, though obviously his upside is apparent. Catcher Dom Nunez and starting pitcher Peter Lambert may be higher on this list than you will hear elsewhere, and Carlos Estevez‘ relief potential bumps him into the 50-grade territory for me.

After having typically appeared in the very hallowed pages of Baseball Think Factory, Dan Szymborski’s ZiPS projections have been released at FanGraphs the past couple years. The exercise continues this offseason. Below are the projections for the Colorado Rockies. Szymborski can be found at ESPN and on Twitter at @DSzymborski.

Other Projections: Arizona / Atlanta / Baltimore / Boston / Chicago AL / Chicago NL / Cincinnati / Cleveland / Detroit / Houston / Kansas City / Los Angeles NL / Minnesota / New York AL / New York NL / Oakland / Philadelphia / Pittsburgh / St. Louis / San Diego / San Francisco / Seattle / Texas / Toronto / Washington.

Batters
Colorado batters produced the third-lowest cumulative WAR among their major-league peers last year, falling just short of the 10-win threshold. That’s one relevant point when considering the Rockies’ prospects for 2016. Another? That the club also hasn’t altered the roster in any substantive way this offseason. There are, of course, other means by which a team can improve from one year to the next. The promotion of young players from within the system, for example. Or simply by way of positive regression. But even ZiPS — which, like other projections systems, is largely a regression machine — doesn’t call for much improvement in that way.

Third baseman Nolan Arenado (612 PA, 4.1 zWAR) appears to have developed into a real star, combining a high-contact, high-power offensive profile with above-average defense. Charlie Blackmon (638 PA, 1.8 zWAR) and Carlos Gonzalez (473 PA, 1.8 zWAR) are also roughly average. After that, however, the returns among the starting contingent are decidedly less encouraging. Outfielder Gerardo Parra (584 PA, 1.0 zWAR), whose acquisition rendered Corey Dickerson expendable, is best regarded as a solid bench player, at this point.

I don’t much care for the move the Rockies made Thursday. I like Jake McGee just fine — he’s an excellent late-inning reliever — and maybe I could understand the trade under different circumstances. But the Rockies don’t actually project to be good, so it seems strange for them to add a reliever at the cost of an affordable, long-term outfielder. Not only that, but of the two prospects exchanged, I like Kevin Padlo more than German Marquez, and Padlo is joining Corey Dickerson in going from Colorado to Tampa Bay.

The trade won’t be the end of the world, and the Rockies could just decide to flip McGee in a matter of months, but for now, it’s an odd decision. This is a move you might expect from a competitive team with a thin bullpen, not a mediocre team with a thin bullpen.

So the Rays add value to the roster and to the farm, and the Rockies add late-inning impact. That’s essentially the summary, with one interesting offshoot being that this seems to set the Rays up for another outfielder trade. There’s another interesting offshoot, though, and it has to do with the Rockies, and with where they play. Sometimes it can be an easy thing to forget about, but the Rockies play baseball literally a mile above sea level, and that makes the team something of an ongoing experiment. It’s always fun to have an opportunity to investigate a new Coors Field question, and the McGee acquisition opens the door.

On Tuesday, I wrote about a trade rumor that, on paper, didn’t seem to make a lot of sense. Ken Rosenthal and Marc Topkin both reported that the Rays and Rockies were discussing a deal centered around Corey Dickerson and Jake McGee, and they’re the kind of reporters who don’t just say things for the fun of it; when they throw names out there, it’s because there is some substance behind the report. And so not surprisingly, two days later, the weird trade rumor is now a weird trade.

McGee heading to #Rockies as part of package for Dickerson, according to @Joelsherman1. Minor leaguers also involved.
