Help Needed: Hitters Who Played Through a 2021 Injury

With the season just over, I’d like some help collecting information on the hitters who played through a 2021 injury. First, I’m not looking for those who may have struggled because of COVID-19 complications but played through a physical injury.

The information can help fantasy managers help point to why a hitter may have struggled when they begin their 2022. Also, my research has shown that these hitters see a production decline that can be incorporated into projections. It’s one offseason data point to have available going forward.

But first, here is how last year’s list faired.

2021 Projected and Final OPS for Hitters Who Played Through a 2020 Injury
Name Steamer Proj Actual Diff
Ronald Acuña Jr. .929 .990 .061
Ozzie Albies .822 .798 -.024
Luis Arraez .789 .733 -.056
Nolan Arenado .827 .806 -.021
Jackie Bradley Jr. .721 .497 -.224
Ryan Braun
Kris Bryant .821 .834 .013
Matt Chapman .829 .717 -.112
Maikel Franco .782 .608 -.174
Joey Gallo .810 .809 -.001
Bryce Harper .908 1.044 .136
José Iglesias .714 .700 -.014
Kevin Kiermaier .687 .716 .029
Scott Kingery .668 .106 -.562
Shed Long Jr. .701 .618 -.083
Max Muncy .820 .895 .075
Shohei Ohtani .833 .964 .131
Roberto Pérez .658 .564 -.094
Jorge Polanco .768 .826 .058
Jose Ramirez .879 .893 .014
J.T. Realmuto .789 .782 -.007
Anthony Rendon .880 .771 -.109
Pedro Severino .715 .691 -.024
Gio Urshela .751 .720 -.031
Christian Vázquez .720 .660 -.060
Luke Voit .810 .765 -.045
Average -.045
Median -.024

The results hold this year with the hitter projection missing by about 25 to 50 points. If Kingery is removed, both the median and average go to -.023. These are almost are just a little higher than the historical values (Average = -.017, median = -0.009).

Please let me know if I’m missing from the following list in the comments. All I ask is that as much information as possible is provided like the location (e.g. hip), when (e.g. spring training), or an article link. Just a name doesn’t help. I started begging on Twitter and here are the hitters I have so far (list from 2017, 2018, 2019, 2020). There is a second table that contains players some people thought played through an injury but I could not find a source to verify. Thanks.

Can you please include what metric this is? I assume OPS.

Didi Gregorius was dealing with side effects from medication to manage his right elbow injury. Might be worth including.

I wouldn’t trust that given that he has dumb ideas about the effects of medication

Andrew Vaughn was/is dealing with a back issue going back a month or so, I believe he went on the IL but was fighting through it before that. You can see the effect in his 15-game rolling wRC+ very clearly, he was really getting going before that.

Yasmani Grandal had a knee issue he was dealing with from spring training until he went on the IL for knee surgery, although that might have been the other knee and the surgery was due to him over-correcting.

Adam Engel has been dealing with persistent hammy and to a lesser extent left shoulder issues throughout the season, who might be fantasy relevant if the lines he’s put up in SSS in 2020 and 2021 are real at all.

Eloy Jimenez tore his pec right before opening day and came back months later, if that counts for your purpose.

Buxton also tore his hip flexor, like Robert, though not as severely I think. Poor guy can’t stay healthy.

Nick Madrigal’s coming back from a bad hamstring tear next year but I don’t believe there was any indication his hammy was an issue before the tear. Same with Robert, I don’t know that he ever actually played through it as a nagging issue, seems like it just happened suddenly and he was out for months. He certainly didn’t miss a beat coming back

Would you consider Eloy Jimenez playing through injury? Maybe he came back too quickly from his pec injury and may have affected his last month and a half

Yastrazemski and Grandal both injured themselves during spring training.

There were articles in the player notes section of Yahoo fantasy baseball. It’s a good way to find information about injuries etc.

According to Yahoo, Grandal had his games per week capped during the first couple of months due to the injury.

Since these are higher than historical values, do you think that extra downgrade is within expected deviations or the results of an additional pressure downwards?

Safe to assume Tapia’s final month of production was affected by his toe injury, I think.

An easy way to find injury articles: https://mlb.com/injury-report. Click “More” under the player’s team. Scroll through older articles on the left. Need to go back further? click on oldest article and wait a moment. Older articles will populate.

“(Rhys) Hoskins said he will have season-ending surgery … to repair a tear in his lower abdomen, an injury he had been quietly playing through this season.

Hoskins always planned to have surgery after the season, but the injury worsened over the past few weeks as he suffered and recovered from an injured left groin.”

He suffered the groin injury on 7/29 and played through it for seven games (with a 260 wRC+).

I would include Mark Canha into this discussion. He had a hip injury in July and after coming back his power completely disappeared along with his average exit velocity!

The emphasis on the word “Physical” implies that Covid complications are somehow non-physical which is a weird implication.
