MLB report on baseballs, home run rates

Baseball’s home run surge of recent seasons is attributable not to a bouncier — or “juiced” — baseball, but rather to better carry resulting in longer fly-ball distances, a committee of experts has concluded. In a report of findings released by Major League Baseball on Thursday and available at, the independent committee chaired by Alan Nathan, professor emeritus of physics at the University of Illinois at Urbana-Champaign, concluded its research had achieved “partial success,” in that it had discovered that reduced drag on the baseballs was responsible for the rising home run rate but had not found any changes in properties of the balls that could account for the reduced drag.
