Chris Carter’s Record Strikeout Rate in Context
Of late, the author has encountered more than one concerned internet citizen making a comment to the effect that Houston corner-type Chris Carter has recorded, thus far, the highest strikeout rate of any qualified batter in major-league history. Indeed, as the table below indicates — of the ten highest single-season strikeout rates since 1913 (i.e. the year since which we have contiguous strikeout data) — these concerned citizens are also generally honest ones.

To wit:

Rank	Name	Team	Season	PA	K%
1	Chris Carter	Astros	2013	526	36.9%
2	Mark Reynolds	D-backs	2010	596	35.4%
3	Adam Dunn	White Sox	2012	649	34.2%
4	Dave Nicholson	White Sox	1963	520	33.7%
5	Mark Reynolds	D-backs	2009	662	33.7%
6	Mark Reynolds	D-backs	2008	613	33.3%
7	Rob Deer	Brewers	1987	566	32.9%
8	Jack Cust	Athletics	2008	598	32.9%
9	Rob Deer	Brewers	1986	546	32.8%
10	Mike Napoli	Red Sox	2013	534	32.6%

What one finds here is a collection of power hitters from the past 25 years, basically, who compensated for a lack of contact with power and/or patience. What one also finds is Dave Nicholson, who seems to have produced a 1.6 WAR in 1963 as a left fielder for the Chicago White Sox — and ultimately a career WAR of 1.7 in 1661 plate appearances.

If one’s ambition, however, is to determine the place of Chris Carter’s 2013 season in all of baseball of all time, one must consider his numbers relative to the context in which they’ve been recorded. For, as a brief inspection of the leaderboards at this site reveals, the 2013 season has produced the second-highest league-wide strikeout rate of the last 101 years.

With a view to examining which players have produced the most prolific strikeout rates relative to their peers, the author has first identified the league-average strikeout rate (strikeouts per plate appearance, that is) for every season since 1913. The author has then divided every qualified player’s seasonal strikeout rate (since 1913, as well) by the relevant league-average rate for that year. The result is an index stat, K-, which measures strikeout rate relative to league average, where a higher figure represents more striking out.

Here are the results of those calculations:

Rank	Name	Team	Season	PA	K%	Lg K%	K-
1	Vince DiMaggio	Bees	1938	611	21.9%	8.7%	252
2	Pat Seerey	Indians	1945	485	20.0%	8.5%	235
3	Jimmie Dykes	Athletics	1922	581	16.9%	7.2%	235
4	Gary Alexander	– – –	1978	564	29.4%	12.6%	233
5	Boze Berger	Indians	1935	504	19.2%	8.3%	231
6	Babe Ruth	Yankees	1922	495	16.2%	7.2%	225
7	Dave Nicholson	White Sox	1963	520	33.7%	15.3%	220
8	Vince DiMaggio	Bees	1937	539	20.6%	9.4%	219
9	Dave Kingman	Mets	1975	543	28.2%	13.0%	217
10	Vince DiMaggio	Pirates	1943	651	19.4%	9.0%	216

Three Notes
• Old brother both to Dom and Joe, center-fielder Vince DiMaggio is responsible for the most prolific strikeout rate of the last 100 years — not only recording the highest rate relative to league, but also having produced three of the ten-highest adjusted strikeout rates over that interval. While DiMaggio’s career rate of 19.7% is precisely average in 2013, it’s more than double the overall rate of 9.1% registered league-wide between 1937 and -46.

• By this methodology, Carter’s 2013 season is only the 66th-worst so far as strikeout rate relative to league is concerned. His index figure: a 187 K-.

• It’s very possible that a more responsible way of conducting a study such as this one would be to find the z-score for every player’s strikeout rate for every season since 1913. In addition to being the more responsible method, however, this would also be the considerably more time-consuming one.

Today’s Complete Schedule
Here’s the complete schedule for all of today’s games, with our very proprietary watchability (NERD) scores for each one. Pitching probables and game times aggregated from MLB.com and RotoWire.

Note that these NERD scores are calculated using the methodology introduced recently and designed to account for the influence of playoff odds on the watchability of games. ***Unlike in recent iterations of this table, the author has adjusted the day’s NERD Game Scores such that, combined, they average 5.0.*** This allows said table to resemble more closely the Game Scores that have appeared here over the preceding four months.
