If there’s still such a thing as newstands anymore, the issue of Baseball America at your local one (i.e. your local newstand) is that publication’s annual “Tools” edition. No, it’s not (as you might suspect from the title) an issue dedicated entirely to relief pitchers with questionable taste in facial hair. Rather, it’s in this edition of the magazine that the editors of Baseball America attempt to isolate the players — major- and minor-leaguers — with the best baseballing tools (hitting for average, hitting for power, speed, etc.).
Beyond the results of a survey to which each of the league’s 30 managers responded, the issue also includes an attempt by author Matt Eddy to find five-tool players “by the numbers” (subscription required, I think).
After a brief discussion of what a “plus” tool might look like when quantified — and also some notes on the obvious limits of such an endeavor — Eddy suggsts this as a methodology:
For the sake of this exercise, let’s identify an above-average hitter as one who bats at least .285/.360/.460 with an isolated power of .175. That’s a 110 percent bump across the board (and then rounded down slightly to please the eye).
To this, Eddy also adds a speed component (more than 20 stolen bases) and runs his criteria through Baseball Reference’s Play Index for all player seasons 2000-10 — the results of which you can find here. (Note: it appears as though Eddy’s power criteria in that search is actually 20-plus homers and not a floor of a .175 ISO, but the results come out similarly.)
The big winner using this methodology is Bobby Abreu, who meets all of Eddy’s criteria in seven of 11 possible seasons. Hanley Ramirez qualifies in four seasons, while Alex Rodriguez finishes third with three “five-tool” seasons.
Eddy’s experiment is an interesting one, both in and of itself, and also for its potential to be nerd-ified — which, this being FanGraphs, that’s what I’ve endeavored to do in what follows.
