Entirely Relevant Preamble
Among the entire surfeit of spring numbers considered in yesterday’s edition of the Notes, one such number suggested the possibility that Atlanta right-handed prospect Julio Teheran has produced the best performance of spring training so far. The data revealed that Teheran had struck out 25 (or ca. 32%) of the estimated 73 batters he’d faced during his five spring starts — a rate which, when regressed against spring averages, is the highest among all pitchers. While further inspection reveals that Teheran has, in fact, faced 74 batters (i.e. one more than originally suggested), the point still remains: relative to the amount of innings he’s thrown, Teheran has probably been the most effective of the spring’s pitchers.
What one wonders is this: “How is it that nearly everyone owns a car despite the enormous expense of buying one — not to mention the associated costs, like insurance, fuel, and maintenance?” After that, though, one wonders a second, more relevant thing — namely, “How strong has Teheran’s competition been this spring?”
To address that latter question in full is impossible. Insofar as some batters use spring training to experiment with mechanical adjustments or plate discipline, the “true talent” of those same batters in the moment during which they’re facing Teheran might diverge wildly from previously recorded levels.
That said, with the projections available here at the site, we do have some sense of the talent level of any player Teheran would be likely to face. It’s with that thought in mind that the author had the idea of documenting every batter Teheran had faced this spring, with a view to assaying the strength of those batters relative to major-league average — again, with all possible caveats regarding spring training and how hitters use their time there.
