MLB and its commissioner, Rob Manfred, have frequently denied rumors which the ball has become altered in any way — or “juiced” — to crank out a lot more homers.

This take a look at primarily cooks a cloth to view which elements aspects of it vaporize at which temperatures. Applying that details, researchers can create a molecular profile of the offered materials.

The lessen in drag is probably a results of a smaller, slicker baseball with lessen seams. The adjust in air resistance could add a further five feet for the vacation distance of a fly ball.
