or creating the baseballs, they're coming up with a rounder baseball.

Sports data scientist Meredith Wills. With a doctorate in astrophysics, her first studies were

in publications like the Astrophysical Journal and Solar Physics. But our most recent research

on the 2019 baseball appeared June 25th in the online sports publication, The Athletic.

So how do you make a baseball that's rounder than other baseballs?
