@drhoa3.bsky.social's latest viz at @baseballprospectus.com answers: How long will an injured player be absent? (e.g. Vinnie Pasquantino: Batters on the IL with wrist soreness/inflammation miss an average of 22 and a median of 15 days) Really useful. www.baseballprospectus.com/news/article...

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.

As you might guess, while trending up is a good thing, 2% is not enough to fend off a potential price increase. So here I am asking again to help us keep our price an insanely affordable $45.95 for what you get. It's a great time to subscribe with our Midseason 50 out and the deadline coming up.

Some interesting data in here on how 2025 has played out very differently on the injury front.

while you're checking out our standings, please take a look at @bachlaw.bsky.social's introduction to 2025 PECOTA to see what's changed about the projection system and why we're particularly excited about some gains made on the pitching side:

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.

Be on the lookout for these metrics to arrive on our leaderboards and player pages, and for them to become incorporated into our pitch models. We are thrilled about this work and hope you are as well! www.baseballprospectus.com/news/article...

I didn't post out our weekend Best of BPs, so a little catch up here: @timjacksonsays.bsky.social on what the Phillies (and other teams) are doing to prep for funky pitchers pre-game, and how it works:

We have some of the best injury data and visualizations around, thanks to @drhoa3.bsky.social. He and @robmains.bsky.social write some great, insightful pieces using it throughout the year, like this one dissecting 2024's injury bug:

@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.

Our first BP Annual Comment giveaway, for a premium subscription courtesy of @blandalytics.pitcherlist.com is below! A reminder that these come from the 2024 Annual and thus are referring to the 2023 season:
The player is an athletic outlier. Ninety-eighth-percentile footspeed and 99th-percentile arm strength have made him an elite defender by any measure; he nearly hit 106 mph on a throw and tops out at around 30 feet per second when he's sprinting. To put those cartoonish features into cartoonish context, he's what you'd get if you gave the Popeye's strength to the Road Runner without weighing him down at all. The player can hit the ball hard too, topping out at a solid 111 mph off the bat, but he'll have to trade some of his spinach for carrots if he really wants to improve on offense; his swing decisions made him the worst batter by DRC+ among any with his number of plate appearances. Coupled with a penchant for whiffs, those decisions resulted in a nearly 30-percentage-point difference between his strikeout and walk rates (also the largest among hitters by that cutoff). If he can get his bat into “well-below- average” territory instead of whatever last season represents, then his secondary skills will make him into a star.

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...

As @cdgoldstein.baseballprospectus.com points out BP subscribers get access to a ton of stuff. I work with our injury database and associated visuals. Below is a thread with a glimpse of our injury content.
