Concerning Randall Delgado’s Virtues
Five of today’s starters currently possess a perfect 10 NERD score*. Four of them (i.e. four of those pitchers) have assembled impressive major-league resumes by one means or another — namely, Homer Bailey, Clayton Kershaw, Matt Harvey, and Jordan Zimmermann. The fifth is Arizona right-hander Randall Delgado. What follows is a brief inspection of Delgado’s very high NERD score, sorted more or less by the degree to which it informs said score.
*The present site’s very proprietary and also infallible watchability metric. See below for more information on NERD.
Fielding Independent Pitching
Delgado has recorded an xFIP and xFIP-* of 3.18 and 83, respectively, this season in 39.0 innings — almost all of them as a starter. The former of those marks is 1.4 standard deviations better than average among pitchers who’ve thrown at least 20 innings in a starting capacity.
*Park-adjusted xFIP relative to league (where 100 is average and a lower than 100 is better than average).
Delgado’s main strength thus far has been his capacity to throw strikes. He currently possesses a strike rate of 67.8% — relative to an average rate of 63.4% (again, among pitchers with 20-plus innings as a starter). Delgado’s strike percentage is 1.8 standard deviations above the mean, in this case.
Despite entering the 2013 season having already recorded nearly 130 major-league innings over the last two seasons — and having been regarded as a prospect for some time before that — Delgado is still just only 23 years old, or about 1.3 standard deviations younger than the population of starters with which we’re dealing, the average age of which is 28.
One might imagine that there’s rather a strong correlation between swinging-strike rate and overall strike rate. In fact, it’s rather weak. And perhaps it stands to reason: pitchers who induce whiffs often do so by working outside of the zone or by virtue of pitches with tremendous movement — such that, those pitches at which a batter doesn’t offer are more likely to be called a ball. In any case, Delgado has been excellent in both areas — both overall strike rate (as noted above) and swinging-strike rate. His 10.4% mark is approximately 1.1 standard deviations above the mean for starters, for whom the average is 8.5%. His best pitch to this end has been his changeup, on which he’s recorded a 26.9% swinging-strike rate.

Cleveland at Minnesota | 14:10 ET
Justin Masterson (135.1 IP, 85 xFIP-, 2.4 WAR) faces Scott Diamond (91.1 IP, 113 xFIP-, 0.1 WAR). Of note regarding Masterson, here are his strikeout rates from 2010 to -12, in order: 17.5%, 17.4%, and 17.6%. Now here’s his strikeout rate this season: 24.4%. Probably related is this: Masterson never threw his slider more than 20% of the time those three years; this year, his slider rate is 28.1%.
