Early impact of injuries on MLB teams in 2026: Down and Left = Better Up and Right = Worse Logo size = Total Games Lost to the IL 3 teams (circled in red) have already lost over 1 full game of projected WARP this season. Arizona leads the league in games missed at 241.

Here is a fun one from @robmains.bsky.social ! We explore one of the visualizations available at @baseballprospectus.com to examine team IL usage the last few years. For example the Dodgers have been first in games lost to the IL for 3 straight years. Losing 1,155 more games then the next team!
Data visualization showing IL usage for major league baseball teams. It has 3 separate charts showing number of IL placements, number of days lost, and projected WARP lost for each team. The LA Dodgers lead the league in IL placements, games lost, and projected WARP lost over the last 3 years.

Heat in the Infirmary is a new injury tool over at BP. It's a different way to see multi-year trends. E.g., over the last 3 seasons no team has had more IL stints than the Giants (noted by the tone of gray in the bar chat), but they are only 10th in IL games lost over that same stretch.

@robmains.bsky.social with a great piece on some of the IL trends we saw in 2024. I thought it was especially interesting to see IL stints down noticeably for batters.

I made alternate city logos/icons for every MLB team a couple of years ago. I decided to dust those off for an injury viz. This is every IL placement in 2024. If you click through to the link the viz is interactive. Does anyone have a favorite icon? public.tableau.com/views/2024IL...

In addition to those constantly updated tools, @robmains.bsky.social and I publish many injury-related articles throughout the season. They feature Rob's great writing and analysis, accompanied by timely visuals to help dig into injury trends as they occur.

The Pain Points tool gives context to what injuries are spiking in a given year. For instance, the great hamstring plague of 2021. #neverforget

The IL Team Totals tool displays various stats on a team level from 2018-2024. Total games missed, total days missed, projected WARP missed.

The Injury timeline shows IL stints in a timeline-style format. You can easily see the shape of a season from an injury perspective. There is both a team view (any single season from 2018-2024) and a player-specific view (all seasons from 2018-2024).

The Recovery Dashboard is a detailed IL database. Data dates back to 2016. This is a great place to research how long it takes to recover from a specific injury. Or you could use it to see how many times a player has gone on the IL due to a ruptured testicle. (Thankfully just once, sorry Mitch.)
