Those wacky guys at Universal Medical Systems are back, blowing the lid off another baseball story. According to UMS -- as their press release so helpfully explains -- the baseballs Hank Aaron hit weren't nearly as lively as those Barry Bonds has been hitting.

An accepted methodology of measuring coefficient of restitution demonstrated the hit distance of the baseball has increased approximately 30 feet from the time Hank Aaron retired.

Rawlings became the exclusive supplier for the League's baseballs in 1977, one year after Hank Aaron retired. In the first year alone the League witnessed a 63% increase in home runs (2,235 in 1976 vs. 3,644 in 1977) with the new baseball composition.
