Ruth's home runs were at the epicenter of an offensive explosion in baseball. In 1918, the major league batting average was .254; in 1921 it was .291. The league ERA went from 2.77 to 4.02, runs increased 25% and home runs increased 300% over the same time span. Almost overnight, baseball had gone from the most anemic hitting era in baseball history (the dead-ball era) to what would be the greatest hitting era—the 1920s.

A few factors have been cited for the dramatic increase in offense. One major reason was that baseball in 1920 outlawed the spitball pitch (with some exceptions), the emery (scuffed) pitch, and all unorthodox pitching deliveries. The spitball was a devastating pitch to the batter, as it gave a pitcher great movement on the ball, especially downward. Another factor for increased scoring was the league mandate to regularly replace the baseball during a game. Previously, the same discolored, tobacco-stained ball was used over and over until it was literally falling apart. The overused ball would lose its resiliency, making it much more difficult to hit it for distance. The impetus for this change was the death of Ray Chapman in 1920, who was killed when he was hit in the head with a dirty, darkened pitched ball that may have contributed to him losing the baseball in the hitting background.

Another reason given for the increase in home runs was that more players were emulating Ruth's full, free swing. Before Ruth and the Live Ball Era, the emphasis was for batters to choke up on the bat and hit for direction, not distance. With his swing, Ruth showed it was possible to hit a prodigious amount of home runs, and more players started to swing for the fences. With the home run now a weapon, more managers lessened their previous absolute control of the offense, and they started to play for the big inning by giving their players freedom to swing away. By 1921, stolen bases were half the total from just a few years earlier, and the use of the sacrifice and hit and run, additional overused strategies during the dead-ball era, also decreased.

Skeptical of the new offense in the game, some baseball writers of the time claimed the baseball was livened (usually done by winding it tighter, or changing the cork center, or both). This assertion even became accepted as a fact over time, even though there was no scientific evidence the ball had changed. One study in August 1920 confirmed the ball was the same as in previous years, and early in 1921, also hearing rumors about the "juiced" ball, National League President John Heydler launched his own investigation and also concluded the ball was no different. Heydler's findings stated the outlawing of the spitball was the predominant factor for the increased scoring. Those who claimed the ball was livened may not have had hard evidence, but they had history and statistics on their side, as never in baseball history had there been such a quantum leap in offense over such a short time.
