On January 26, 1963, Major League Baseball’s Rules Committee increases the size of the strike zone. The zone will stretch from the top of the batter’s shoulders to the bottom of the knees. The committee hopes the return to the 1950s strike zone will result in a decrease in runs scored.

The results will exceed the committee’s expectations, and after the “Year of the Pitcher” in 1968, the strike zone will be tweaked again to give the hitters a break.
