A Club with Fewer Members
The numbers paint a stark picture of the decline. In 2015, 28 pitchers reached the 200-inning mark. A decade later, in the 2025 season, that number plummeted to just three. The trend has been steadily downward for years, accelerating recently as front
offices armed with data change the fundamental approach to pitching. Once a benchmark for a quality starter, the 200-inning season is now an outlier, an achievement reserved for a select few who defy the modern logic of the game. Even Cy Young Award winners are falling short of the milestone, signaling a major philosophical shift across the league.
The Third Time Through the Order
One of the biggest drivers of this change is a simple but powerful analytical concept: the "third time through the order penalty." Data overwhelmingly shows that the more times a hitter faces the same pitcher in a game, the better the hitter performs. By the third at-bat, familiarity kicks in. Hitters have seen the pitcher's full arsenal, timed his delivery, and can make better adjustments. Simultaneously, the starter is often experiencing fatigue, which can lead to a slight dip in velocity or less sharp movement on his pitches. Fearing this predictable decline, managers now preemptively pull their starters, often in the fifth or sixth inning, rather than risk giving up a big inning to the top of the lineup.
The Rise of the Specialized Bullpen
As starters have been asked to do less, bullpens have been asked to do more. Teams now invest heavily in building deep rosters of relief pitchers, each with a specific skill set. For much of baseball history, the bullpen was for failed starters or emergencies. But with the creation of the "save" statistic in 1969, roles began to formalize. Today, bullpens are a collection of specialists: left-handed matchup guys, high-velocity setup men, and lights-out closers. A manager might prefer a fresh reliever with a 98-mph fastball for one inning over a tiring starter, even if that starter is the team's ace. This strategic shift makes pulling a starter early not a sign of failure, but a calculated move to maximize matchups and prevent runs.
Protecting the Investment
Starting pitchers are among the highest-paid athletes in sports, with teams investing hundreds of millions of dollars in their arms. With pitcher injuries on the rise, organizations are increasingly cautious about workloads. The prevailing logic is that fewer innings and lower pitch counts will reduce wear and tear, hopefully preventing catastrophic injuries and prolonging a pitcher's career. While the direct statistical link between fewer innings and better health is still debated, the financial risk is undeniable. Teams would rather pay a pitcher to be dominant for 170 innings and turn the game over to the bullpen than risk losing their multi-million dollar asset to an injury from pushing him too far.
From Pacing to Max Effort
The very nature of pitching has changed. In previous eras, a starter would pace himself, knowing he was expected to go deep into the game. Today, the philosophy is often "max effort" from the first pitch. Pitchers are encouraged to throw as hard as they can, with maximum spin on their breaking balls, for as long as they are in the game. This approach is designed to generate more swings and misses, but it's also more physically taxing. It’s a trade-off: higher effectiveness over a shorter duration. This intensity makes it nearly impossible to maintain elite stuff for seven, eight, or nine innings, further reinforcing the trend toward shorter starts.
