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.

Some later additions from the comments (the table with the links is a mess to redo, so I’ll try to redo it after I think the list is done).

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