FiveThiryEight (March 1) -- There has been a remarkable upswing in home run power in Major League Baseball since 2015, and the league commissioned a study to find out why. According to Alan Nathan, a professor emeritus of physics at Illinois and one of the physicists on the commission, the task force found that all the characteristics that MLB regularly measures, including the weight, circumference, seam height and bounciness of the ball, were within ranges that meant variations in the baseballs were unlikely to significantly affect home run rates.
