What's Going on With the Baseballs?

About this event

Wednesday, June 2 | 12:30 PM ET

Batting averages are down, strikeouts are up, and baseballs are spinning off pitchers’ fingers like never before. When Major League Baseball made changes to its ball this season, the idea was to create more offense by having more balls in play instead of home runs. Yet, we saw six no-hitters and one faux-hitter (Madison Bumgarner’s in seven innings) before we even got to the last week of May. Did MLB’s decision to reduce the weight of the baseball have the unintended consequence of raising the seams and giving pitchers an edge? Ask questions and get the latest from this panel of scientists and experts.

Featured Speakers (Additional speakers to be announced)

Rob Arthur is a Chicago-based independent journalist and data scientist. He uses data to write stories about baseball, criminal justice, and politics, as well as consulting for various companies from MLB teams to law firms.

Dr. Meredith Wills is a Data Scientist for SportsMEDIA Technology (SMT). Her independent research on the composition of Major League baseballs--published in The Athletic and Sports Illustrated--has shed new light on the offensive changes in recent seasons, earning her the 2020 SABR Analytics Conference Research Award for Contemporary Baseball Analysis. In her spare time, Wills is a knitting designer, partnering with both the Baseball Hall of Fame and the Negro Leagues Baseball Museum to create reproductions of vintage baseball sweaters. She has a B.A. in Astronomy & Astrophysics from Harvard University, and a M.S. and Ph.D. in Physics from Montana State University-Bozeman.
