Bat Advisory Committee statement -- Dec. 2, 2010

As an element of the ongoing follow-up from the Board of Directors Meeting in January, and at the request of its National Member Organizations, USA Baseball has assembled a panel of scientists -- the USA Baseball Bat Advisory Committee -- to provide advice on baseball bat performance standards in amateur baseball. The group will provide its recommendations to USA Baseball President Mike Gaski and USA Baseball Executive Director Paul V. Seiler, who will then convey these views to the National Member Organizations of USA Baseball.

The Baseball Bat Advisory Committee will work in close conjunction and consultation with other relevant USA Baseball Committees and will initially consist of five members: Dr. Fred Mueller, Dave Halstead, Dr. Glenn Fleisig, Dr. Alan Nathan and Dr. Daniel Russell.

The biographies of these individuals are below:

Dave Halstead is the Technical Director of Southern Impact Research Center as well as an active instructor and lecturer in the areas of head and neck injury, human biomechanics and injury with the University of Tennessee, the American Society of Mechanical Engineers and others. In addition to his duties at SIRC, Halsted is the Laboratory Director of the University of Tennessee Sports Biomechanics Impact Research Lab and Principal Scientist with the University's Engineering Institute for Injury and Trauma Prevention in the College of Engineering.

Alan M. Nathan, Ph.D., has been Professor of Physics at the University of Illinois at Urbana-Champaign for more than 30 years. His primary scholarly work has been in the area of experimental nuclear/particle physics, and he has an international reputation in that field. In recent years, he has added the physics of sports, primarily baseball, to his research portfolio. He has published numerous scientific papers on the subject and has provided scientific advice to a variety of organizations on the issue of bat performance. He currently serves as a member of the scientific panel that advises the NCAA on bat and ball performance.

Frederick O. Mueller, Ph.D., is a professor of Exercise and Sport Science at the University of North Carolina at Chapel Hill. He is also the Director of the National Center for Catastrophic Sports Injury Research and the Research Director for the National Operating Committee on Standards for Athletic Equipment. Fred is also a member of the USA Baseball Medical and Safety Advisory Committee.

Glenn Fleisig, Ph.D., has worked with Dr. James Andrews and other colleagues to understand and prevent injuries in baseball and other sports in his twenty years at the American Sports Medicine Institute. Dr. Fleisig has made more than 200 scientific presentations at meetings throughout the world and has published more than 95 scientific papers, including "Relationship between Bat Mass Properties and Bat Mass Velocity."

Dr. Daniel Russell, Ph.D., is an Associate Professor of Applied Physics at Kettering University in Flint, Mich., where he teaches physics and acoustics to undergraduate students. He earned his Ph.D. in Acoustics from the Pennsylvania State University in 1995, specializing in structural acoustics and vibration. For the last eight years he has investigated the vibration and acoustic signatures of baseball and softball bats. His research explores the physics of the trampoline effect in hollow metal and composite bats and the vibration in the handle that contributes to sting. He also has an extensive website with articles explaining the physics of baseball and softball bats and the metrics used to measure bat performance.
