Dr. Meredith Wills was born on a Major League Baseball Opening Day, but it was not a run-of-the-mill Opening Day: It was the day Henry Aaron tied Babe Ruth’s home run record. Her father, who grew up watching Aaron play, went out and bought his newborn daughter a baseball bat. “He was absolutely convinced that I was going to be something in the game,” says Dr. Wills. The elder Wills’ vision was prescient. Dr. Wills has been busy over the past several years researching and solving the mysteries within a seemingly simple but beloved object: the baseball. The impact of Dr. Wills’ research is changing the game of baseball and what we know about MLB operations.
