Kaelen Culpepper and the Mildest Hamstring Strain in Baseball History

When the Twins called up Kaelen Culpepper to take over as their shortstop on August 7, one of the noteworthy things about the decision was that they forfeited an (admittedly remote) shot at scooping up some significant future value. Because Culpepper came up with 52 days left in the season, he was all but guaranteed to exceed the thresholds that exhaust a player's rookie eligibility: 130 at-bats, or 45 days on the active roster. That meant Culpepper would not be eligible for the 2027 Rookie of the Year Award, and that he could not net the team a prospect promotion incentive (PPI) draft pick by winning that honor or finishing well in MVP voting over the first two or three years of his career.

For most players, this is a minor consideration, but it was a major talking point. Some fans believed the Twins were holding Culpepper and Walker Jenkins back from being called up purely to preserve the possibility that they might someday net them a draft pick. Calling up Culpepper just a week before the date at which they could have done so without compromising that chance was another indication that the organization felt a sense of urgency to win in 2026, adding to the indications they'd given by being moderately aggressive at the August 3 trade deadline.

Then, something a little funny happened. On September 15, on a ground ball to shortstop, Culpepper came up limping slightly. He left that night's game against the Yankees, and the next day, the Twins placed him on the 10-day injured list with a left hamstring strain. By then, it was abundantly clear that the team was not going to make the playoffs, so it was equally clear that Culpepper's rookie season was over. Or was it?

"I think it’s one of those situations that we think it’s best for him to make sure" it doesn't become a bigger issue, Shelton told reporters that day. “Now, on the flipside, there is a possibility he could come back with two games left. Our goal right now is that. Now, if it doesn’t happen, obviously, we will make those kind of arrangements. But the goal we’ve had for him, because it is a mild strain, is to see if the last two games are available.”

In a vacuum, that was very, very strange. It jibes a bit with Shelton's unusual approach to managing the team and the clubhouse, but even taking that into account, it was strange. Teams don't bring back injured players who are important to the long-term outlook of the organization for a couple of games at the end of the season. At the time, it felt like Shelton was merely paying lip service to that option, as a way of underscoring how mild the strain was. It still seemed extremely unlikely Culpepper would play again before the year was over.

He did. Throughout his minimum-length stay on the shelf, the team and the player were unwavering in their belief that he would return, and he played the final two games of the season, despite the Twins having been officially eliminated from playoff contention the previous weekend. He finished the season with a .274/.328/.393 line in 117 at-bats. He also finished, thanks to that 10-day stay on the IL, with 42 days of active roster time. Culpepper will appear on top prospect lists this winter, and he'll be Rookie of the Year- and PPI-eligible next season, after all.

There is no chance—none whatsoever; do not take this to Conspiracy Theory Town—that Culpepper was not actually injured, or that the Twins acted improperly by putting him on the IL in the wake of his hamstring tweak. Now, though, I think we can safely say a couple of things:

1. "Tweak" is a better word for it than "strain". It was as mild an issue as a high-level athlete is ever likely to have with that muscle, which is always so troublesome.
2. If the Twins had still been in serious contention when he got hurt, Culpepper would have played through the problem.

Baseball people are fond of reminding everyone that no one is 100% healthy in September, at the end of a grueling 162-game season. This is the kind of injury to which they're alluding, and it's one players push through all the time. Culpepper could have pushed through this one, too. If that weren't true—if it were actually an injury severe enough to unequivocally require 10 days off—there is no chance he would have come back for the two meaningless games at the end of the year. 

This highlights something that's good to keep in mind, anyway, when it comes to injuries in sports: there's almost always ambiguity. There are often perfectly sound cases for or against any particular course of action, from a routine day off to an IL placement to surgery. Health is a skill for big-league athletes, made up of two component skills: avoiding injuries, and playing through ones minor enough to permit that. The former has much to do with one's genetics, conditioning and playing style. The latter depends on those things, too, but it's a tricky needle to thread. One must be careful not to increase the chances of a more severe injury, without losing time that doesn't need to be lost. 

Culpepper was never going to push through this particular injury, extremely mild though it clearly was—not because he couldn't have or didn't want to, but because once that issue arose, the Twins saw an opportunity. It's unlikely that Culpepper wins an award or garners enough MVP votes to earn them a PPI draft pick someday, but it's not impossible. Why foreclose the possibility, when you've been given a sudden and unexpected chance to maintain it? You don't have to love that there were incentives for the Twins to err so much on the side of caution, but they were there. It was a kelp-and-sailboat situation—kind of.

The Twins didn't fudge anything or make any unethical choices; they didn't have to. This was just a very fortuitous hamstring tweak, as well as a very mild one. It gave them a chance to add a bit of value to their long-term portfolio, and while they're unlikely to realize any actual value from it, it cost them nothing to take the opportunity.

Culpepper could, perhaps, have learned a little about playing through mild injuries by staying on the field for those 10 days, but that's the kind of thing you'd rather have players learn when it's necessary—when the stakes are much higher, that is. Besides, that would have involved some risk of worsening the injury. They minimized any chance of having to worry about Culpepper's legs going into the winter, and they gave him a slightly greater chance to make extra money next season (there are bonuses for Rookie of the Year Award vote-getters, as well as value going to the winner's team in the form of a future pick) while helping themselves. They even got him back onto the field to enjoy a few last cheers from the fans at Target Field, before the campaign ended—though if those two days had tipped him over to no longer being rookie-eligible, it feels safe to guess that his hamstring issue would have been season-ending, after all.

The games may have been meaningless for the 2026 Twins but they aren’t for Culpepper.

Absolutely correct! Certainly, to listen to him talk about it and having been around him even a little bit, I think that's right.

AND,

There's still no chance he comes back to play those games if there's any injury that actually forced him to be placed on the IL, as opposed to merely making him eligible to be.

I mean, I doubt it affected him either way outside of not seeing full pitching. He did a minimal stint and I'm sure he was still out on the field taking grounders, learning to read pitchers off the mound, taking BP as a player should, and pretty much doing everything, albeit probably around 60-70% speed. But there is nothing wrong with that. 

I for one thought the injury was more severe than it was believed, because as a Twins fan, we can't catch a break when it comes to injuries that are typically normal tweaks or strains. But I am glad that we might have 3 or more potential players eligible for ROY contention going into next year.

I thought that days on the major league IL counted towards service time.  Is that wrong?

Got a good smile from your comment about 'there's almost always ambiguity regarding injuries."  Tell that to Brock Faber.
