You’ve probably heard it a thousand times by now. The "workhorse" is dead. If a guy makes it through the sixth inning, we treat him like he just ran a marathon in hiking boots. But honestly, if you look at how Major League Baseball starting pitchers are actually being used in 2026, the "death of the starter" narrative is kinda lazy. It's not that they can't go long. It’s that the math—and the sheer physical violence of a modern 100 mph fastball—has changed the job description entirely.
Think about Tarik Skubal or Paul Skenes. These guys aren't just "pitching." They are essentially performing a series of high-intensity explosive sprints with their elbows. When Skubal won the AL Cy Young recently, he wasn't doing it by pacing himself. He was doing it by maintaining a 32.2% strikeout rate and a WHIP under 1.00. That is pure dominance, but it comes at a cost.
The 200-Inning Myth and the New Reality
We used to obsess over the 200-inning mark. It was the gold standard. In 2025, Logan Webb led the league with 207 innings, and Garrett Crochet was right there behind him. But look at the rest of the field. Most "aces" are now living in the 170 to 185-inning range.
Is that bad? Not necessarily.
The quality of those innings has skyrocketed. In the 2025 postseason, we saw a massive shift. Starter ERA- dropped to 91, which is significantly better than the historical average of around 98. Basically, when Major League Baseball starting pitchers are on the mound now, they are more effective than they've been in years. They just aren't out there as long. Managers have realized that a dominant five innings from a guy like Yoshinobu Yamamoto is worth way more than seven innings of a guy "figuring it out" while his velocity dips.
Why the Third Time Through is a Killer
It’s the "Times Through the Order" penalty. You've likely heard the term. By the third time a hitter sees a 98 mph heater, their brain has calibrated. The advantage shifts.
- First time through: Pitchers hold a massive edge.
- Second time: It’s a toss-up.
- Third time: Hitters start teeing off.
Because of this, the average start in 2025 hovered around 5.1 innings. Some people call it "soft." I call it optimized. Why would you leave your $300 million asset out there to get hammered by the top of the order when you have a bullpen full of guys throwing 101 mph?
The Great Velocity Tax
Let's talk about the elephant in the room: injuries. The UCL—that tiny ligament in the elbow—is under siege. We are seeing more flexor tendon and forearm issues than ever before.
A lot of fans blame the pitch clock. They think the lack of recovery time between pitches is snapping arms like dry twigs. But the data from Samford University and recent NIH studies suggests otherwise. The pitch clock hasn't actually led to a "statistically significant" spike in Tommy John surgeries.
The real culprit? Max effort.

Every single pitch is now a maximum-velocity event. When Shane Bieber or Jacob deGrom (who managed 185 strikeouts in limited 2025 action) take the mound, they aren't "pitching to contact." They are hunting whiffs. The torque required to generate that spin and speed is simply more than the human body was designed to handle for 250 innings a year.
The Rise of the "Splitter" Era
If 2024 was the year of the sweeper, 2026 is shaping up to be the Year of the Splitter.
Look at what Yamamoto did in the 2025 World Series. His splitter was basically unhittable. Pitchers like Joe Ryan and Kevin Gausman have leaned into this, using the pitch to neutralize high-velocity bats without needing to redline their arm on every single four-seamer. It's a survival tactic as much as it is a strategy.
Who Actually Owns the Mound Right Now?
If you're betting on who the best Major League Baseball starting pitchers are heading into the rest of 2026, the list is getting younger and weirder.
- Tarik Skubal (Tigers): He’s the undisputed king. Sub-2.00 ERA potential every time he walks out there.
- Paul Skenes (Pirates): The "Skenes-mania" is real. He’s already hitting 216+ strikeouts a season.
- Garrett Crochet: After that monster 2025 where he threw over 200 innings and struck out 255, he's proven he's not just a "flamethrower" but a durable ace.
- Zack Wheeler: The veteran exception. He still manages to look like an old-school workhorse while using new-school stuff.
Then you have the wildcards. Sandy Alcantara is working his way back. Hunter Brown in Houston has turned into a legitimate strikeout machine. Even someone like Trey Yesavage is making a name for himself as a "pitching nerd" favorite because of his command.
What Most Fans Get Wrong About "Durability"
There is this idea that pitchers today are "fragile."
Actually, they are stronger than they’ve ever been. The training at places like Driveline Baseball has turned these guys into lab-grown monsters. The problem is that the league has gotten better. Hitters are better at identifying pitches. They have better data.
To beat a modern MLB hitter, you have to be perfect. You can’t just "toss it in there" at 91 mph and hope for a flyout. If you do, that ball is landing in the third deck. This pressure to be elite on every single delivery is what wears pitchers down, not a lack of "grit."
The Financial Shift: Paying for Peak, Not Length
Look at the contracts. Teams aren't necessarily paying for 200 innings anymore. They are paying for "Impact Innings."

A guy like Yoshinobu Yamamoto gets paid because his innings are high-leverage. If he gives you 160 innings of 2.50 ERA ball, that is worth more to a front office than 210 innings of 4.20 ERA ball. We are seeing a shift where the "Net Worth" of a pitcher—take the recent comparisons between Shane Bieber and Trey Yesavage—is tied to their ability to dominate the strike zone, not just stay on the mound until their arm falls off.
Actionable Insights for Following the Rotation
If you want to actually understand how the game is moving, stop looking at "Wins" and "Losses." They are basically useless stats for individual pitchers now.
Instead, track these three things:
- Stuff+: This measures the physical characteristics of a pitch (velocity, break, release point). It tells you who should be winning, even if they have a bad luck game.
- Whiff Rate: If a pitcher can't make guys miss, they won't last in 2026. Period.
- Average Velocity by Inning: Watch if a guy’s heater drops from 98 to 95 by the fifth. That’s the signal he’s done for the day.
The role of Major League Baseball starting pitchers isn't disappearing; it’s just evolving into a specialized, high-intensity sprint. We might never see another 300-inning season, but the guys we have now are arguably the most talented athletes to ever touch a baseball.
To keep up with the changing rotation, prioritize watching pitchers who have at least three plus-pitches and can maintain velocity into their 80th pitch. These are the "new workhorses." They might only go six innings, but those six innings will be the most dominant baseball you've ever seen. Focus on K/BB ratios rather than innings pitched to identify the true top-tier talent in your fantasy leagues or when evaluating team strength.
