Jacob Misiorowski’s Unprecedented Season: A Deep Dive into His Historic Performance

Jacob Misiorowski is undeniably making waves this season, and with 14 starts under his belt, his numbers are nothing short of extraordinary. Leading the National League in several key categories, Misiorowski’s performance invites a closer examination within the rich tapestry of baseball history.

In the annals of AL/NL history, only 18 qualified starters have concluded a season with an ERA better than 1.34. Remarkably, 16 of those instances occurred during the “Deadball” era from 1900 to 1919. The two outliers include Tim Keefe, who in 1880 finished with a 0.86 ERA over just 105 innings, and the legendary Bob Gibson, whose 1.12 ERA in 1968 is still revered. Yet, the context shifts when we adjust for league-wide offense and ballpark effects, leading us to a new metric: ERA+. Here, Misiorowski shines brightest, boasting a staggering 307 ERA+, the highest ever recorded by a qualified starting pitcher.

The 2000 season of Pedro Martínez serves as a benchmark for excellence, as he posted a 1.74 ERA that year, translating to an impressive 291 ERA+. Meanwhile, Greg Maddux made his mark with exceptional back-to-back seasons in the mid-90s. However, Misiorowski has outstripped all of these legends with his current ERA+.

When examining his FIP (Fielding Independent Pitching), Misiorowski’s 1.68 ranks 15th all-time, and after filtering out Deadball pitchers, he stands second only to Martínez in 1999 and Corbin Burnes in 2021. His 0.736 WHIP not only leads the current season but would also set the record for any qualified starter, narrowly surpassing Martínez’s 2000 mark. Additionally, allowing just 4.3 hits per nine innings, Misiorowski is on track to shatter existing records.

In terms of home runs allowed, while Misiorowski’s mark of 0.4 per nine innings doesn’t threaten historical records due to the current high-home-run environment, it still ranks among the best of recent seasons. Strikeouts could be a different story; while Misiorowski might not break any strikeout records, he has an outside chance of joining the elite club of pitchers with 300 strikeouts in a season, a feat accomplished only nine times this century.

Despite his remarkable achievements, Misiorowski’s walk rate remains merely excellent, with a 5.95 strikeout-to-walk ratio that places him 80th all-time among qualified starters. It’s essential to recognize that while these 14 games are impressive, they represent a small sample size in the grand scheme of a season.

Historically, there have been 42 instances where a pitcher struck out 131 batters while maintaining an ERA of 1.34 or lower over 14 starts. However, many of these instances are clustered within the same streaks, making Misiorowski’s current run even more noteworthy.

When comparing Misiorowski’s season to others, Jacob deGrom’s 2021 campaign stands out. DeGrom’s 1.08 ERA and jaw-dropping 373 ERA+ in 15 starts showcased a level of dominance rarely seen. While it’s crucial not to speculate on Misiorowski’s future, the parallels are intriguing, as both pitchers exhibited extraordinary skills during their respective stretches.

As it stands, Misiorowski is performing at a Hall-of-Fame level, and the only pitchers who have matched his effectiveness over similar spans are either Hall of Famers or players whose legacies compel fans to reminisce. The true longevity of Misiorowski’s brilliance remains uncertain, but for now, he is captivating audiences and delivering performances that will be remembered. Fans should relish this moment, for one day they will undoubtedly say, “You should’ve seen Miz.”
