There have been accusations for years that the Major League ball is “juiced,” thus accounting for the increasing power numbers.
MLB officials have categorically denied that, and last year, commissioned a study of the baseball and how it’s produced.
In the landmark 85-page independent report replete with color graphs, algorithms and hypotheses, a group of 10 highly-rated professors and scientists chaired by Alan Nathan determined that the ball is not livelier or “juiced.” Nathan is a professor emeritus of physics from the University of Illinois at Urbana Champaign.
The surge in home runs “seems, instead, to have arisen from a decrease in the ball’s drag properties, which cause it to carry further than previously, given the same set of initial conditions – exit velocity, launch and spray angle, and spin. So, there is indirect evidence that the ball has changed, but we don’t yet know how,” wrote Leonard Mlodinow, in the report’s eight-page executive summary.
