How Is Each Decade Unique?

Great question! Let me start with the most dramatic transformation in baseball history - the rise of power hitting. In the Dead Ball era (1900s-1910s), teams averaged just 0.14 home runs per game. Then Babe Ruth changed everything.

The 1920s saw home runs nearly triple. The 1950s brought another leap with integration and stronger athletes. Then came the steroid era - the 2000s peaked at 1.07 home runs per game, almost 8x the Dead Ball era. The 2010s pulled back slightly as testing got stricter.

Here's the most shocking change in baseball - the death of the complete game. In 1900, pitchers finished what they started nearly 80% of the time.

Today it's under 3%. The 1950s brought relief specialists. The 1990s brought setup men. Now we have openers, bulk guys, and the whole bullpen game. A starter going 7 innings is an achievement. Going 9? Basically extinct.

This one's fascinating - stolen bases tell the story of baseball's strategic pendulum.

The Dead Ball era was all about small ball - 1.2 steals per game. Teams scratched and clawed for runs. Then Ruth showed everyone you could just swing for the fences, and stolen bases collapsed to 0.3 per game by the 1950s. Why risk an out when you can hit it over the wall? Then Lou Brock and Maury Wills revived the running game in the 1960s-70s. Rickey Henderson dominated the 1980s. Speed peaked again at 0.77 per game before analytics convinced teams that stolen bases weren't worth the risk.

You're right - strikeouts define the modern game more than anything else.

In 1900, teams struck out 1.2 times per game. Today it's 7.4 - over 6x higher. Pitchers throw harder, have nastier stuff, and there's no stigma about striking out anymore. Hitters swing for power and accept the Ks. The 2010s set strikeout records almost every year. The game went from contact and manufacturing runs to three true outcomes: walk, strikeout, or home run.

Let me show you the back-and-forth battle through ERA trends.

The Dead Ball era (sub-3.00 ERA) belonged to pitchers. Then hitters exploded in the 1920s-30s with ERAs over 4.00. The 1960s saw a pitcher renaissance - Bob Gibson's 1.12 ERA in 1968 was so dominant they lowered the mound. The steroid era (1990s-2000s) pushed ERA back over 4.40. Now we're seeing another correction as pitching depth, bullpen usage, and velocity have improved. It's an eternal arms race - and each decade tips the balance differently.
