In 1968, Bob Gibson posted a 1.12 ERA for the St. Louis Cardinals, the lowest mark in 54 years. That same season, Gibson won 22 games with 268 strikeouts, dominating hitters so completely that Major League Baseball lowered the pitcher’s mound from 15 to 10 inches the following year. One man’s dominance rewrote the rulebook.
The 1968 Dominance
Gibson wasn’t just good—he was nearly unhittable. He completed 13 games, threw 304.2 innings, and allowed just 198 hits all season. Batters hit .164 against him in September alone. His 11.5 WAR made him the decade’s best pitcher. The Cardinals won the World Series, and Gibson earned Series MVP honors with a masterful performance that left hitters helpless.
The Rules Changed Because of Gibson
MLB’s front office convened after 1968 because the game had tilted too far toward pitchers. Gibson became the face of that imbalance: his 1.12 ERA was so extreme that owners feared fans would stop coming to games with no runs being scored. The mound reduction was direct and unprecedented—Gibson and his peers had seized too much advantage. It remains one of the few times baseball altered its fundamental rules in response to a single player’s dominance.

The Competitor Who Never Quit
Gibson was more than statistics. He pitched with an intensity that intimidated: hard stare, no smile, no surrender. He won three World Series (1964, 1967, 1968) and was elected to the Hall of Fame in 1981 with 337 votes from 401 ballots. His competitive fire was legendary—even in practice, he refused to ease up. At 34 in his final season (1975), he finished with 3,117 career strikeouts, a testament to his sustained excellence across two decades.
FAQ
Why was Gibson’s 1.12 ERA so extreme?
Gibson threw a fastball over 95 mph in the 1960s, a devastating slider, and had near-perfect control. Hitters had no answer. The higher mound (15 inches) gave him a mechanical advantage too. The combination was lethal.
Did the mound reduction hurt Gibson?
Yes. His ERA jumped to 2.18 in 1969 and never returned to 1968 form. But he remained excellent—he won 20 games in 1970. The rule change was designed to balance the game, not destroy it.
Is Gibson the greatest pitcher ever?
That’s debatable. Most place him in the top five with Cy Young, Walter Johnson, and Sandy Koufax. His 1968 season, however, is undisputedly the best single season by a pitcher in the modern era.
