Knuckleball Research

Much of my time recently has been devoted to my ongoing research into the mysteries of the knuckleball. I have divided this section into four parts:
Analysis of Knuckleball Trajectories
Wind Tunnel and Related Research
Other Studies Using PITCHf/x Tracking Data
Knuckleballs in the Media
The R. A. Dickey Nasty Pitch Gallery

ANALYSIS OF KNUCKLEBALL TRAJECTORIES

WIND TUNNEL AND RELATED RESEARCH

  • Aerodynamics of a Kunckleball, a seminal article by Prof. Robert Watts and his student Eric Sawyer of Tulane University, published in the November 1975 issue of American Journal of Physics. The article investigates the dependence of the aerodynamic forces on a baseball as a function of the orientation of the ball in the four-seam configuration.
  • THE KNUCKLEBALL In this brief article, the author parametrizes the results of the Watts/Sawyer experiment, then uses those results to calculate simulated knuckleball trajectories.

  • Aerodynamics of the Knuckleball Pitch: Experimental Measurements on Slowly Rotating Baseballs, an article by Prof. John Borg and Michael Morrissey from Marquette University and published in American Journal of Physics, October 2014. This research is a more modern version of the Watts work, extended to include the all-important two-seam configuration. In addition to the wind tunnel studies, the authors actually interviewed Mets knuckleball pitcher R. A. Dickey for the article. The research was the Master's thesis of Mike Morrissey.

KNUCKLEBALLS IN THE MEDIA

  • R. A. Dickey on 60 Minutes Lesley Stahl interviews R. A. Dickey on a 60 Minutes episode, which aired on April 14, 2013.

  • How a Baseball Star's Tricky Pitch Strikes Out Hitters--and Baffles Physicists This is an excellent article that appeared on November 12, 2012 in the on-line edition of Discover Magazine, written by Associate Editor Andrew Grant. The baseball star is R. A. Dickey. Grant gets all the facts right and does a good job posing the outstanding problems that still baffle people like me.

  • Knuckleball! A documentary film by Ricki Stern and Annie Sundberg. Quoting from their publicity blurb: "This classic sports story recounts the 2011 journey of the last professional knuckleball pitchers: Tim Wakefield, a 17-year Red Sox veteran, and Mets up-and-comer R.A. Dickey. Together with just four other living knuckleballers, they shine a light on their remarkable brotherhood and the shared pursuit of honor and craftsmanship." It debuted in April 2012 at the NYC Tribeca Film Festival, it had a special viewing at SABR42 convention in July, and it is scheduled for general release later in 2012.

  • The Knuckleball: The science behind why it's so damn hard to hit, a video shoot at Parkland College. The clip features left-handed knuckleball pitcher and Grinnell College physics undergraduate student Andrew Kelley, who worked with me in summer 2012 on knuckleball research. Published June 23, 2012 by ReutersTV.

  • Nobody Hits It This story appeared in Sports Illustrated in 1959 and is about HoF knuckleballer Hoyt Wilhelm. Starting on page 4 is a section called "Scientific Expose of the Knuckler."

  • A New Take on Why a Knuckleball is so Hard to Hit. A very nice graphic that accompanied an article about R. A. Dickey in the Washington Post, June 2012.
