August 31, 1909 – A. J. Reach Co. patented the cork-centered baseball. Previously the balls had a hard rubber core to them. It sounds harmless enough, after all the core is buried under a leather cover and inner bindings. The stats tell a different story though.
According to ThisDayinBaseball.com the number of .300 hitters jumped from eight in 1910 to 27 a season later in the American League. The league’s earned run average will go from 2.53 to 3.34.
