Let’s be real: watching Nolan Arenado last season was tough. For a decade, the guy was a metronome. You could set your watch to 30 homers and a Gold Glove. But then 2025 happened, and suddenly, the "is Nolan Arenado hurt?" searches started blowing up. The swing looked slower. The ball wasn't jumping. He looked... well, human.
Now that it’s January 2026 and the dust is finally settling on that blockbuster trade to the Arizona Diamondbacks, we actually have the answers. It wasn’t just "old age," though turning 35 in April is its own kind of injury in pro sports. It was a classic case of a gamer trying to be too tough for his own good.
The 2025 Injury Timeline: It Started with a Finger
If you want to know if Nolan Arenado is hurt right now, you have to look at how he finished last year. He didn't just fall off a cliff because he forgot how to hit; he was basically playing one-handed for a significant chunk of the summer.
Back in late June 2025, specifically around a series in Cleveland, Arenado jammed his right index finger. Most guys take a week off. Nolan? He’s built differently—or maybe too stubbornly. He tried to play through it.
The result was a disaster. Because his finger was swollen and vibrating every time he made contact, he started subconsciously changing his swing to avoid the pain. This is what trainers call "compensation." You fix one problem by creating a bigger one. By August 1, that compensation turned into a full-blown right shoulder strain.
The Cardinals finally had to step in and shut him down. He missed six weeks. When he eventually came back in September for a rehab stint with Double-A Springfield, the power was gone. He finished the season with a .237 average and only 12 home runs. For a future Hall of Famer, those aren't just bad numbers—they're "something is broken" numbers.
Is Nolan Arenado Healthy for 2026?
So, the big question for Diamondbacks fans: is he still hurt?
The short answer is no, not in the medical sense. Reports coming out of Phoenix following the January 13 trade suggest that the shoulder has fully healed. The Cardinals wouldn't have been able to move him—and Arizona wouldn't have taken him, even with St. Louis eating $31 million of the contract—if he hadn't passed a physical.
But there’s "healthy" and then there’s "baseball healthy."
Honestly, Arenado admitted himself that his biggest mistake was not going on the IL the moment the finger injury happened. He told reporters that he didn't evaluate himself the right way. That’s a huge admission. It shows that while the physical injury might be gone, the mechanical damage from months of "playing hurt" is what he’s fighting now.
Why the Diamondbacks Took the Risk
Arizona is gambling on the bounce-back. They aren't paying for the 2025 version of Arenado. They're paying for the guy who, before the shoulder issue, still had elite contact skills.

Check out why they pulled the trigger:
- The Price Tag: St. Louis is paying for the vast majority of his remaining $42 million. Arizona is essentially getting a legend for $11 million over two years.
- The Defense: Even with a bad shoulder, Nolan’s glove didn't die. He’s still an upgrade at the hot corner after Eugenio Suárez left.
- The Video Work: Word is Arenado has already been firing off hitting videos to the D-backs coaching staff. He’s obsessed. He knows his reputation is on the line.
The Wear and Tear Factor
We can't talk about Nolan being hurt without mentioning his back. If you look at his injury history over the last five years, "back tightness" and "lower back strain" appear more often than any of us would like.
It’s the curse of the third baseman. All that diving, twisting, and torquing takes a toll. While the shoulder was the headline injury of 2025, the chronic back issues are what usually sap a player's power over a full 162-game grind.
In St. Louis, the management (specifically Oli Marmol) was often criticized for not resting veterans enough. In Arizona, expect Mike Hazen and the staff to be much more protective. They need him for October, not for a random Tuesday in May against the Rockies.
What Most People Get Wrong About His Decline
A lot of fans think Nolan is "washed." They see the exit velocity numbers—which, admittedly, were in the bottom 10th percentile last year—and assume the tank is empty.

But there’s a nuance here. Arenado’s strikeout rate stayed incredibly low (around 11%). That’s rare. Usually, when a player's eyes or reflexes go, they start swinging at air. Nolan is still hitting the ball; he just wasn't hitting it hard.
If the shoulder is truly 100%, that whip in his swing should return. He won't be a 40-homers-at-Coors guy again, but a healthy Nolan Arenado in Chase Field? He could easily hit 20-25 bombs and bat .270. That’s a massive upgrade for a Diamondbacks team that struggled to find stability at third last year.
Actionable Insights for the 2026 Season
If you're following Nolan's health this spring, keep an eye on these specific markers:
- Opposite Field Power: When Arenado’s shoulder or back is bothering him, he stops driving the ball to the right-center gap. If he’s spraying doubles to all fields in Spring Training, he’s healthy.
- The "Dive Test": Watch his first few defensive gems. If he’s popping up quickly after a diving stop, his back is holding up.
- Rest Cycles: Watch how Arizona manages his off-days. If they are proactive about giving him one game off every week, it’s a sign they are managing chronic wear-and-tear to prevent another "compensation" injury like we saw in 2025.
Basically, Nolan Arenado isn't currently on the injured list, but he is at a crossroads. He's healthy enough to be traded, healthy enough to swing a bat, and motivated enough to prove the Cardinals wrong for "waving the white flag" on him. Whether his 35-year-old frame can survive the desert heat for six months is the only real question left.
