Baseballs used from 2015-2017 had greater aerodynamic carry

A study commissioned by Major League Baseball indicated that baseballs used from 2015-2017 were not juiced, but that “changes in the aerodynamic properties of baseballs” resulted in greater carry and a home run surge during that period.

The 10-person committee released results of its study Thursday, and found that Rawlings, which manufactures baseballs for MLB, “achieved much greater precision than allowed by the MLB specifications” regarding parameters such as weight, size, and and the ball’s COR (coefficient of restitution).

In addition to exploring humidor options – currently only used at hitter-happy ballparks in Phoenix and Denver – MLB said it will:

• Make updates to the existing production specifications of baseballs and develop additional specifications for the aerodynamic properties of the ball.
• Perform aerodynamic testing on baseballs
• Create standards for “mud rubbing,” a process by which new balls are rubbed down by home teams using a specific mud from the New Jersey area.
• Form a scientific advisory council.

So, the baseballs need to be taken to a wind tunnel?

Just do ct scans and compare the cores.
