Writing a e book is a Herculean job to start with, and in my inimitable approach, I made it even more durable when writing my 2017 e book on the Corridor of Fame, The Cooperstown Casebook, by difficult myself to compose concise 200–250 phrase summaries of the 220 main league gamers who had been enshrined at that time in addition to a number of dozen previous, current, and future candidates. My objective in doing so was to provide the reader a thumbnail information to those gamers’ careers whereas shining some recent mild on even probably the most acquainted ones utilizing superior statistics. I had no scarcity of choices, besides, I want I had all of the instruments then that I do now. Right here I’d like to spotlight considered one of them as a part of our sequence on helpful website options you’ll discover at FanGraphs.
Contemplate the case of Dazzy Vance, a colourful and dominant right-hander who made his identify with the Brooklyn Dodgers within the Nineteen Twenties and ’30s. Vance was 24 years outdated when he debuted with the Pirates in 1915, however quite a lot of arm troubles restricted him to only 33 main innings by his age-30 season. Lastly ache free after elbow surgical procedure (most likely to take away bone chips), he resurfaced with Brooklyn in 1922, and on the energy of his mixture of a blazing fastball and a pointy overhand curve “with a sweep that might disgrace a windmill,” as one author described it, he led the NL with 134 strikeouts that season, and proceeded to repeat the feat in every of the subsequent six seasons as properly. His 262 strikeouts in 1924 was the very best whole by any NL pitcher moreover Christy Mathewson within the 1901–1960 span, and the very best by any pitcher in both league between the beginning of the Dwell Ball period (1920) and the US’ entry into World Struggle II (1941).
Whereas I had sufficient confidence in my analysis to guide Vance’s Casebook capsule with, “Relative to his league, Vance struck out batters at a better charge than [Nolan] Ryan, [Roger] Clemens, [Pedro] Martinez — any of them…” I anxious that by explicitly quantifying his talent on this space that I’d both open myself to error or make much more work for myself, for the reason that temptation was to enter additional element on the topic and maybe calculate such information for each enshrined pitcher. Little did I do know that inside a 12 months of the e book’s publication that I’d not solely be a part of the workers of FanGraphs however suggest the creation of a leaderboard to deal with such questions with a number of straightforward clicks.
The function, which we name “+ Stats” or “Plus Stats,” launched in April 2019. Like wRC+ or OPS+, the + is shorthand for an index stat with a baseline of 100, the place 120 represents a efficiency 20% higher than common and 80 a efficiency 20% worse than common. The system, as Invoice Petti outlined it whereas pondering alongside related traces right here at FanGraphs in 2012, is Ok%+ = [(Pitcher’s K% / League Average K%) * 100]. In contrast to wRC+ or OPS+, our fundamental plus stats for pitchers and batters are at present not park-adjusted, however they’re nonetheless useful for comparative functions — notably throughout eras for charge stats which have different broadly over time. You could find them on our particular person and group leaderboards, utilizing the “+ Stats” button below the Stats tab. Right here it’s, highlighted in inexperienced:
That’s a leaderboard displaying the 2023 season’s prime 10 pitchers by Ok%+ utilizing a 50-inning cutoff. You possibly can in fact select a spread of seasons (break up or mixed) or customized dates, and outline your innings or plate look minimums, simply as you’d for many of our different stats. To get again to Vance, it seems that he’s not simply the chief in Ok%+, he’s the runaway chief, the one pitcher with greater than 600 innings who has a charge at the least double that of the league:
Vance is properly forward of some extra acquainted and fashionable kings of the Ok, resembling Ryan, Randy Johnson, Sandy Koufax, and Bob Feller. In the meantime, Billy Wagner, who simply missed being elected to the Corridor of Fame in January, has the third-highest charge at that cutoff — the second-highest if I elevate the ground to 800 innings. For the primary eight years of Wagner’s Corridor candidacy, I used to be capable of report that his 33.2% strikeout charge was the very best of any pitcher with at the least 800 innings, however final 12 months Kenley Jansen reached that threshold and is now forward at 35.9%, whereas Aroldis Chapman has gotten his profession again on monitor and is at 698 innings with a 40.3% charge. Relative to his league, Wagner nonetheless has the sting on Jansen, and Chapman must keep away from regression and attrition over the subsequent couple of seasons if he’s to supplant him.
Right here’s a customized leaderboard I constructed, once more rating pitchers by Ok%+ but additionally displaying their uncooked strikeout charges and totals in addition to another helpful stats, this time with a 1,000-inning cutoff:
With this device, you may see that whereas the Massive Unit struck out batters at greater than twice the speed of Lefty Grove, their charges relative to their respective leagues are very shut. By way of the BB%+ column, you may as well get a way for which pitchers had been the wilder ones from this group; on this case greater numbers are dangerous, and we will see that Ryan’s stroll charge was 46% worse than common. In the event you type the desk by whole strikeouts, you may see that among the many 19 members of the three,000 strikeout membership, Greg Maddux (100) obtained there with a league-average charge over 5,008.1 innings and Phil Niekro (105) was fairly near common, with Ryan and Johnson on the different finish of the spectrum.
We will use these instruments on hitters as properly. In 2019, when Jeff McNeil was tearing up the league, I went trying for different gamers with equally excessive batting averages and low strikeout charges — that’s, AVG+ and Ok%+ — relative to their leagues, first amongst his contemporaries, after which traditionally. Right here’s what the complete interface for such a leaderboard appears like:
For the desk I constructed to match McNeil to different hitters, I really needed to construct two leaderboards, then be a part of them collectively in Excel and filter the outcomes to seek out the gamers in that “household” of performances:
Most McNeil-Like, by AVG+ and Ok+
The Plus stats have been hiding in plain sight for almost 5 years now. We’re planning to incorporate them on our participant pages within the not-too-distant future, which ought to elevate their profile a bit, and so as to add a number of different charge stats into the combo. They’re enjoyable to mess around with, and function a fantastic instance of our builders’ potential and willingness so as to add new instruments to our arsenal — and to yours. One of the best ways to help the additional improvement of such instruments, and to help the positioning on the whole, is with a FanGraphs Membership.
