On March 13, 1943 — The major leagues approve a new official ball manufactured by the Spalding Company for the upcoming season. Instead of the usual combination of cork and rubber, the inside of the ball is made up of recycled cork and balata, materials not needed in the war effort. Officials insist the ball will have the resiliency of the 1939 ball, but the players will express dismay that they cannot drive the new ball and point out the dearth of runs and homers in 1942 even with the old ball.
