The (Mostly) Complete List of Knuckleball Pitchers

A couple of months ago, I asked an innocent question on the Knuckleball HQ Community message board. I had seen the list of pitchers who threw the knuckleball, but wanted to know if anyone had compiled a list of pitchers who made their living with the knuckler, rather than the posted list of guys (like Gibson) who threw it only once or twice in a career.

It seemed like a simple question, and in fact there was a simple answer - Rob Neyer has compiled such a list in the Neyer/James Guide to Pitchers. However, when I got his book, I discovered that beyond the 70 knuckleball pitchers he lists, there are more guys who threw the knuckler than I ever imagined (at least 250). Neyer states that shortly after the knuckleball was introduced, there were a "great number of pitchers" who threw it, but simply referred to it as a "slow ball." Furthermore, in the 30s and 40s, Neyer says: "I suspect that something like half the pitchers in the majors occasionally threw a knuckleball." How times have changed.

This got me thinking. Was it even possible to compile a full list of everyone who threw the knuckler? Maybe not... but it turns out I'm just crazy enough to try. So, after spending a couple weeks reading through the Neyer/James Guide to Pitchers, and probably far too much time researching individual pitchers on the internet, I've compiled what I believe is the most complete list so far of pitchers who threw the knuckleball.

I've broken the list down into four categories, based on how often the pitcher tossed up a knuckler - from real knuckleball pitchers down to guys who threw only one in their career. However, It turns out that even these categories fail to fully capture the diversity of players who have thrown a pitch they called their knuckle ball, fingernail-ball, floater, flutterball, dry-spitter, or Cuban butterfly. So before going to the list, it may help to present a bit of history.

The pitch we now know as the knuckleball was first thrown in the major leagues during the first decade of the twentieth century. Four pitchers: Eddie Cicotte, Ed Summers, Nap Rucker, and Lew "Hicks" Moren were among the first to throw it, and all may have played some part in its invention. It is likely that the pitch was first invented by Eddie Cicotte in the summer of 1905, while he was a teammate of Nap Rucker in the minor leagues.

Cicotte threw the pitch off of his knuckles, hence the name. In the summer of 1906, however, Cicotte and Summers pitched together in the minors, and Summers developed a variation of the pitch he called the "finger-nail ball." This pitch was essentially the same one thrown today by Tim Wakefield, and by the time Cicotte and Summers reached the majors in 1908, both were throwing this "finger-nail ball." Why the term "knuckleball" stuck while "finger-nail ball" and other terms did not remains a mystery.

Some nineteenth century pitchers, such as Toad Ramsey and Old Hoss Radbourn were known to throw a pitch called a "drop-curve" or "dry spitball" which in retrospect, some have said was a knuckleball. However, as Rob Neyer points out, "Ramsey was moderately famous at the turn of the century, and if he'd thrown the dancing variety of the knuckleball, people would have said that when Summers and Cicotte arrived in the majors." A more likely explanation for the pitch thrown in the nineteenth century is that it is some variety of what we now call a knuckle-curve.

This confusion between the knuckleball and the knuckle-curve extended well into the twentieth century, and makes any list of knuckleball pitchers from before WWII somewhat suspect. Some of the most famous knuckleball pitchers from this period, such as Freddie Fitzsimmons and Jessie Haines, may actually not have thrown what we now consider a knuckleball. Based on descriptions of how they threw the pitch, and how the ball behaved on the way to the plate, it seems likely that what they threw would be called a knuckle-curve today. For this reason, I have also included a list of pitchers who threw the knuckle-curve.

Finally, before getting to the list, I want to acknowledge my sources. In compiling this list of knuckleball pitchers, I relied heavily on The Neyer/James Guide to Pitchers by Rob Neyer and Bill James, as well as information from baseball-reference.com, baseball-library.com, baseball-almanac.com, thebaseballpage.com, and the Knuckleball Headquarters web site. Any quotes below come from these sources.

On to the list....

Knuckleball Pitchers

These are the guys who were known for throwing the knuckleball. Using Rob Neyer's definition, this includes any pitcher "who would not have been in the majors without his knuckleball, or whose knuckleball was considered his best pitch, at least for a time."
