How long can Tarik Skubal stay on top of his game?

On Saturday night, Detroit Tigers’ ace Tarik Skubal made baseball history by collecting his second straight American League Cy Young award. For all the conversation around Skubal as he prepares for his last season prior to free agency, the basic calculus for all parties involved revolves around the fundamental question; how long can Tarik Skubal stay at this level?

Since the middle of the 2023 season when he settled in after 2022 flexor tendon surgery, Skubal has been the best pitcher in baseball. When we talk about his arbitration battle with the Tigers, whether he should be traded or extended, and what he will ultimately be paid in a long-term contract next offseason, it all comes down to an assessment of how good Tarik Skubal will be going forward, and for how long.

Assuming he has another great season in 2026, which certainly isn’t guaranteed, Skubal is set to ask for $400 million in free agency over a 10-year span, and he may end up making more than that. To be worth such a deal, Skubal needs to have numerous great seasons ahead of him, and to be able to still produce good numbers in his decline phase. No one is going to expect Cy Young caliber production out of him for 10 years, but they’ll be paying like he can average well above average production over the life of the deal. In reality, deals like this are really only about the first 5-6 years, with a big spending team expecting to eat much of the remaining contract.

The game has changed so much over the last quarter century that drawing reasonable comparisons to other great pitchers is difficult.

We can look to former Tigers ace Justin Verlander as one possible point of comparison. The future Hall of Famer has been the most valuable pitcher in the game over the last 20 years, though the title of “best” may go to Clayton Kershaw. It’s difficult to use JV as a comp because Verlander is a freak. He was throwing 100 mph by the time he was 21-22 years old, and he was able to reach back for triple digits with his max fastball for over a decade before settling into steady mid-to-high 90’s velocity for much of another full decade. Skubal had his first major arm surgery when he had Tommy John in his freshman year of college. A 2022 flexor tendon injury also required surgery and cost him over a season of work. Verlander had one stretch in 2014-2015 of core and shoulder trouble, but was otherwise unscathed until he finally blew out his UCL in 2020. He then returned at age 39 and won his long coveted second American League Cy Young award in 2022.

Verlander possesses a once in a generation type combination of arm strength, durability, hunger, and work ethic that can really only be surpassed by the likes of Nolan Ryan and Randy Johnson, and even now he’ll land himself a solid one-year deal in the coming weeks as he reaches his 43rd birthday. Roger Clemens and Pedro Martinez had better careers than Verlander, though he’s closing in on Pedro, but they didn’t throw as hard nor maintain that kind of top shelf velocity deep into their careers.

Comparing aces

Other contemporary examples of a true ace, rather than just a good pitcher who had a peak season or two, may be a little more instructive than Verlander. So let’s take a quick look at the other top pitchers over the last 20 years and see what happened from age 30-35.

This chart below is the top 20 pitchers in fWAR from 2005-2025. Essentially you can see how much in fWAR they were worth prior to their 30’s, and then how much fWAR they earned in successive seasons. I left out guys who started their career in the 90’s like Roy Halladay. The 2020 season throws a bit of a wrinkle into this, and makes it a lot more of a project to take all these pitchers and get a fair average by each year of their career from age 30 onward. It’s not exactly cutting edge statistical analysis, but this is enough to give you a pretty good picture of the risk of a serious performance drop off from age 30 on.

Again this only tells you so much, but it’s already pretty clear that paying a pitcher $35-40 million a year in their 30’s is never going to go very well. There’s a pretty good chance he’ll be a good pitcher for several more years, but the odds of many more Cy Young award caliber seasons isn’t great. Beyond 34, really only Justin Verlander remained a pretty valuable pitcher for a long time.

We should also note that most of these pitchers either never had a Tommy John surgery, or didn’t have one until they were already into their 30’s. DeGrom has already had two, and Zack Wheeler had the surgery in 2015 and came back very strong. Adam Wainwright had the surgery in 2011 and came back strong for another decade. Chris Sale had the surgery in 2020. Otherwise, the only other TJ guy on the list is Verlander, and he was 37 at the time with a crazy amount of mileage and high velocity heat behind him.

Now let’s consider the actual specimen himself.

Skubal is at the height of his powers

Tarik Skubal’s main attributes as a pitcher are velocity, a pretty unique fourseam fastball shape, a deceptive delivery, and one of the best changeups in baseball. The velocity isn’t going to last, but the other traits do bode well for Skubal remaining a pretty good starting iptcher even when he’s sitting 95 mph rather than the 97.6 mph he averaged in 2025. Frankly there’s a pretty good chance we’ve already seen peak velocity from the big left-hander. He averaged 95.8 mph in his 2023 return from flexor tendon surgery. He averaged 96.8 mph in winning his first Cy Young in 2024. That’s a pretty incredible trendline, but it can’t last forever.

Still, even when Skubal eventually falls back to averaging 95-96 mph again, his seam-shifted changeup is still going to remain a great weapon. Per Statcast, Skubal’s changeup was worth 26.8 runs above average, easily the best changeup is baseball. Christopher Sanchez of the Phillies was second at 19.8 runs above average, and only three other pitchers were above 10 runs above average. Certainly a great changeup benefits from a great fastball, and the changeup won’t be as effective when his velocity declines, but it’s so good it should remain a well above average pitch for Skubal for many years to come.

The distinctive thing about Skubal’s fourseamer is the fact that it’s basically a straight pitch. His ability to tie up right-handed hitters inside is predicated both on the velocity and deceptive delivery, but it’s also the fact that not many left-handers have a fourseamer with that shape. It’s almost a 97-98 mph cutter, and hitters cannot get used to the idea that it won’t run back over the plate at all. And just as he’s got you recognizing that fact, he’ll mix in a sinker that does swing back 10 inches on average more than the fourseamer, and he can start that pitch right at a right-handed hitters’ hands and nail the inner edge of the strike zone. There’s just no way to get experience against that combination of velocity and stuff.

If there’s any flaw in his game right now, it’s that Skubal doesn’t really have a good breaking ball indpendent of his other pitches. His slider plays up because his two main offerings are both elite, but it’s really a pretty average slider that thrives on velocity and the need for hitters to worry about the fastball-changeup combination. It’s a straight 90 mph pitch that doesn’t really break at all, with very pedestrian spin considering the velocity he’s throwing with. As the effectiveness of his two main pitches declines along with his velocity, he isn’t going to have that third pitch to fall back on unless he comes up with something new.

Of course, maybe he will. One of the unifying tendencies of the greats is the insane work ethic and dedication to keep making adjustments as their peak phase of raw athleticim starts to decline. Skubal can occasionally dump in a solid curveball, and as his velo declines perhaps he leans more into the sinker and converts to a pitcher who gets more ground balls than fly balls, playing the sinker and changeup off each other. When you have such outsized weapons, coming up with adjustments as they decline may be a little bit more straightforward.

Full steam ahead to 2026

For now, there’s nothing to suggest that Skubal isn’t going to go right back out there in 2026 and win his third straight Cy Young award. Garrett Crochett, Hunter Brown, Cole Ragans, and a few others, will try and step up to challenge him, but until Skubal starts losing velocity or gets injured, he’s going to remain really hard to beat.

At some point in the next few years, Skubal is basically guaranteed to have a letdown year. Maybe it will be an injury, maybe wear and tear will just sap a little gas out of the tank, but it’s bound to happen. No pitcher can maintain a peak like this for a half decade or more, particulary once they’re into their 30’s. Then the question will be if Skubal can adapt. Justin Verlander has been able to do so because he has a great slider, outstanding command, and the spin rates to continue throwing a good fastball even without the ability to scrape triple digits. Max Scherzer mixed fastball types and leaned into his excellent slider-changeup combination to continue pitching well through his mid-30’s.

Perhaps Skubal will simple mix fourseamers and sinkers more, while still relying on a changeup that wreaks havoc on either-handed hitters to remain a well above average starting pitcher. Right now, his stuff is so overpowering that he doesn’t rely on pinpoint command, but at lower velocities he may be forced to spot his stuff a little more precisely rather than just aiming over the middle and trusting his stuff.

What I hope this post illustrates, is why signing Skubal long-term was never really in the cards for the Tigers. With no apparent interest in an early extension after 2023 or 2024, he was always going to free agency.

Based on the Tigers payroll, they could afford $40 million a year for great Skubal. They would still be fine paying him $40 million a year for just good Skubal. The club is paying Javier Báez $24 million to be a quality utility player and that isn’t killing them right now. One underwater contract is not the end of the world. But what Scott Harris probably can’t do under the Ilitch family’s payroll restrictions, is pay $40 million a year for 5-6 seasons while Skubal is injured or just a fairly average pitcher down the road. That’s the fear. Such a deal could work out for the Tigers, but it’s hard to fault Scott Harris for not making that move without the Ilitch family committing to eating some of the back of that contract without limiting the rest of the Tigers’ payroll should things go that way. This is the kind of deal that ownership has to make happen. No doubt if Mike Ilitch were still around he would be pretty likely to push it through. Unlikely that the Ilitch family trust controlling the Tigers now feels the same way.

If Skubal is great for 2-3 more seasons and then is still a good starting pitcher into his mid-30’s, he’ll be plenty worth his money. If it all starts to unravel for him in his early 30’s, whoever signs him long-term is going to have a problem. But, for the likes of the Dodgers or the Mets? Just another huge deal they can easily absorb.

For now, we still have 2026 to enjoy this, so let’s just hope Skubal has at least one more monster year in him.
