In a pair of recent posts at this site, Matthew Kory has examined — first before the Royals’ great success and then also after it — has examined what sort of effect the World Series champions might have on the roster-construction philosphies of baseball’s other 29 teams. Both pieces are founded on a reasonable assumption — namely, that it’s common for franchises to imitate the process utilized by the league’s great victor, with a view to also imitating the product. The Copycat Effect, is how one might characterize this. Why felines specifically have been singled out for their mimetic inclinations, I can’t say. That the phenomenon exists seems like a reasonable possibility.
The current post resembles Kory’s own efforts in that the objective is to isolate and explore the most pronounced traits of baseball’s championship club — those traits which, were an organization tempted to emulate the champion, they would themselves identify as most important. Where it differs from Kory’s work, however, is that the intent here is to look towards the future. Instead of examing which current major-league players or teams most embody the Royals’ strengths, what I’d like to ask is which prospects do that. In other words, I’d like to ask this: which rookie-eligible players would a general manager, attempting to best imitate the Royals, set about acquiring (or keeping, as the case may be)?
That’s the guiding inquiry of the current post. How to answer it, though?
First, this way: by identifying those traits endemic to the Royals. Again, Kory’s work is helpful here. In the latter of his two posts, he identifies the traits which most distinguished Kansas City from the rest of the league: a low strikeout rate among the club’s hitters, strong baserunning, elite defensive ability, and a talented bullpen. For the purposes of this post, I’ll be ignoring pitchers. I’ll do it for a number of reasons, but largely because betting on even the near-term success of relievers is a fool’s errand. So the focus will be on hitters.
That’s the first step towards answering the question. The second: to utilize the recently published Steamer 600 projections for 2016. Here’s how I began: for all 4043 players for whom a forecast has been produced, I calculated the z-scores in each of three categories: strikeout rate (where lower is better), baserunning runs relative to average, and defensive runs (which accounts both for fielding runs and positional adjustment). I then averaged together the z-scores for each of those three categories. Reason dictates that the resulting figure should represent to what degree the relevant player might offer the skills possessed by Royals players.
Below are the top-10 rookie-eligible players by that methodology. Note that Age represents 2016 baseball age and all heading titles preceded by -z- represent z-scores.
Royals Prospects Who Aren’t Royals: Attempt No. 1
So, an immediate observation: this is a list full of catchers plus also Jose Peraza and Hanser Alberto. Because catchers receive such a large positional adjustment (+7.5 runs per every 450 plate appearances), they’re inclined to gravitate towards the top of lists like this. Where projections are concerned, positional adjustments aren’t subject to regression and translation like other metrics. Strikeout rate, baserunning, fielding runs: where only minor-league data is available, Steamer is conservative — particularly so regarding the latter two variables. As such, the large catcher’s positional adjustment unduly rewards catchers. Catchers are important, but merely presenting a list of doesn’t seem entirely in keeping with our objective here. We’ll have to refine our methodology.
