Clayton Kershaw Pitched Like a Reliever
You might have heard that Clayton Kershaw is good at pitching. He’s Hercules and Sandy Koufax merged together at the molecular level. He’s faster than a speeding bullet, more powerful than a locomotive, and able to throw over tall buildings with a single curve. He’s SuperPitcher. Much like Mike Trout, Kershaw is the sort of athlete who could easily serve as the genesis of a daily newsletter with interesting factoids about said athlete. The more you dig around on statistical leaderboards and in his ledger, the more ridiculous little nuggets of gold you can dig up.
Take, for instance, this:
| Pitcher | IP | WHIP |
|---|---|---|
| Kenley Jansen | 68.2 | 0.67 |
| Andrew Miller | 74.1 | 0.69 |
| Clayton Kershaw | 149 | 0.72 |
| Zach Britton | 67.0 | 0.84 |
| Ryan Dull | 74.1 | 0.87 |
| Nate Jones | 70.2 | 0.89 |
| Mark Melancon | 71.1 | 0.90 |
| Dan Otero | 70.2 | 0.91 |
| Christopher Devenski | 108.1 | 0.91 |
| Seung Hwan Oh | 79.2 | 0.92 |
One of these things is not like the other. WHIP isn’t a perfect indicator of pitcher success, because the number of hits allowed by a pitcher is impacted by the defense playing behind him, and walks are affected by the framing quality of a pitcher’s catcher. It is, however, a generally fun statistic and is usually useful when one is in pursuit of a general picture of a pitcher’s ability to limit baserunners. The full leaderboard is here, and as you can see, it generally consists of pitchers who kicked ass in 2016.
Let’s talk about the top portion of that leaderboard, though, which has been reproduced in the table above. Of the 10 pitchers included here, Kershaw is the only one who’s a full-time starting pitcher. (Devenski started five games but had the bulk of his success in relief.) You have to go down to the 16th spot on the leaderboard to find the next starter, Max Scherzer (who’s followed by Kyle Hendricks and Rich Hill). Scherzer’s WHIP was 25 points higher than Kershaw’s. This is largely due to the fact that Kershaw walked just 11 men all year, and would have set the modern record for strikeout-to-walk ratio had he been a qualified starter.
One of the great injustices of baseball is that Kershaw hurt his back last year, because we’ll never know if he would have been able to keep up that sheer lunacy over the course of a full season. His 1.69 ERA in 149 regular-season innings was lower than Pedro Martinez’s 1.74 in his ridiculous 2000 campaign. Kershaw also bested Pedro’s 2000 in FIP and WHIP, with Pedro taking the edge in DRA. If you look at all starting-pitcher seasons since 2000, set the minimum innings requirement at 140, and sort by WHIP, Kershaw’s 2016 and Pedro’s 2000 represent the top two figures. Four of the top 10 seasons over that timeframe belong to Kershaw. The fact that we’re even conducting a flawed (Pedro threw 217 innings that year, and in a different offensive era) comparison of these two men and not totally throwing the stats out with the bathwater is remarkable.
