The 95% confidence intervals in minutes per game preceding the Achilles tear vs the rest of their season. 10 games: 24.5-33.5 vs 23.2-31.6 15 games: 24.2-33.0 vs 23.2-31.6 A statistical difference, but not a clinical one.

This study is a textbook example of statistical significance not meaning clinical significance. The "small spikes" equated to a couple minutes. I'm confident saying these "small spikes" were ultimately meaningless. It's also the problem of using linear statistics to explain nonlinear dynamics.

#WNBA but present it like a soap opera.

That's technically a knee dislocation for Fedko. Going to be a long recovery.

Twins outfield prospect Emmanuel Rodriguez is back in the lineup at High-A Cedar Rapids after dealing with thumb soreness. St. Paul Saints outfielder Kyler Fedko is out for the season after he tore his ACL, MCL and LCL in his left knee. Fedko appeared in 14 games with the Twins this year.

Teams do *a lot* more data collection behind the scenes than the gen. pop. knows. One of the objective assessments Cerfolio talks about in this interview is force plate testing. Force plate analyses, when done correctly, can reveal quite a bit about an athlete's athletic foundation.

line from Rob Cerfolio's interview at FanGraphs is gonna stick with me for awhile bc so much of public player evaluation has turned the other way: "We’re not solving for Double-A performance. We’re solving for major league impact." blogs.fangraphs.com/cardinals-fa...

The W is up to 366 games lost due to knee injuries this season. Since the start of the 2023 season, 1284 of 3318 games lost have been because of knee injuries. No other body part has caused 500 cumulative games lost. And these numbers are very likely underestimates because of insufficient reporting.

Just in from the Fever: Damiris Dantas has a torn meniscus in her left knee. She underwent knee surgery yesterday and will miss the remainder of the 2026 WNBA season.

Hello

Buckle up folks

This study is a textbook example of statistical significance not meaning clinical significance. The "small spikes" equated to a couple minutes. I'm confident saying these "small spikes" were ultimately meaningless. It's also the problem of using linear statistics to explain nonlinear dynamics.

NBA players’ Achilles tendon tears are linked to small spikes in playing time, study finds

The injury is one of basketball’s most serious. A recent study found that players logged more minutes than their season averages during the 10 to 15 games before their Achilles tendons ruptured.

My bias when evaluating athletes is that since it's functionally impossible to actually improve an athlete's instincts/reaction times and speed, if they grade out poorly in these domains, either stay away or consider early position changes to mitigate any potential negative consequences.

Lucas Seehafer@seehafer.bsky.social · 3d ago

Most of what we think of as "instincts" are just functional reaction times. Determining how to legitimately improve reaction times, speed, and agility (and get those improvements to stock beyond transient improvements) are the holy grails of player dev, particularly at the pro level.

A Short History of Medicine is great

Joey@joeybi4alt.bsky.social · 3d ago

Do you have any medical history book recommendations?

I really enjoy writing and running but those are sports-adjacent, so I'll say reading about medical history and philosophy. People know about the influence of the Greeks and Indians on healthcare throughout the ages, but the Middle East also has a rich and influential history.

What’s your favorite non-sports pastime?

100% correct. It's a glaring problem for many franchises - and a huge advantage for the select few that do the work to integrate departments. Here's what I wrote in my "Hacking the Jumper" article a couple months ago (defector.com/can-the-jump...):

I think there's a misunderstanding about how much communication occurs between a team's sports science staff and front office/coaches/player dev/athletes/etc. I've spoken to multiple sports scientists for multiple teams in multiple leagues. It's a lot less than you'd think, on average.

It does and there is not... I've got a research paper I've been putting off writing up, so maybe I'll do that...but I'll probably doom scroll for trades and fall asleep

Does the bus have a tv? If so, is there a movie playing? If no to all of those, what’re you doing outside of an AMA to entertain yourself?

I get to be on a bus for the next 6 hours. AMA.

Having an entire MLB season cancelled would be so devastating to the sport and to the owners pocketbooks. Zero chance the entire season is lost. They decided to play through a global pandemic for God's sake because they were so concerned about their bottom lines.

Bupkis is my favorite top prospect

Well these two sequences alone have me convinced Lackey would be the best defensive catcher on the Twins *right now*

Aaron Gleeman@aarongleeman.bsky.social · 3d ago

Vahn Lackey was touted as being a high-level defensive catcher with excellent throwing ability. Here's the No. 3 overall pick nailing two runners with perfect throws in his third professional game:
