In 127 years of Major League Baseball, 21 teams have won at least 100 games at least two years in a row. The 2018-19 New York Yankees are one of those teams. And consider this: As the decade comes to a close, no team won more games than the Yankees. They won 921 – 57 more than the team’s chief rival, the Boston Red Sox; 100 more than the San Francisco Giants. And 150 games more than the Houston Astros.

After 342 pages, he does not offer a concrete answer for the epidemic because, at this point, no one really knows.
