I'm very excited to be concocting way-too-early and very incomplete advanced metrics for the WPBL! I'm sure they'll update the league their website with more stats the moment I finish this code, but it's a fun exercise anyway.

A teacher I know in the south has to put these stickers in all of the students' textbooks. It's USSR levels of pointless waste out here.

A sheet of stickers that say "The Gulf of Mexico has been renamed as The Gulf of America."

#Rockies pitcher Tomoyuki Sugano has long had the ability to outperform his peripherals. Strong, wild defensive plays like this have been part of the equation. www.baseballprospectus.com/news/article...

Run scoring has taken a weird, big bump this summer. It's likely due to a one-two punch of the ball changes and the insane summer heat.

How can you not be romantic about baseball? theonion.com/mlb-players-...

Ronald Acuña Jr.: “Before my first game, a veteran came up to me and said, ‘Listen, kid. Don’t ever let an umpire show you what’s underneath his mask. It’ll drive you to madness.’ I thought he was kidding, but then, before my first at-bat, the umpire whispered, ‘Do you want to see?’ and there was smoke funneling out of his mask. I politely declined, but it really freaked me out. I didn’t sleep for a week.”

From the transcript for Arrested Development episode "Sad Sack":

Wayne Jarvis: We’re going to get you, Bluth. We’ll give you a few minutes to think about what you want to do. [To Cho] He knows less than anyone we have ever questioned.

Narrator: G.O.B. knew too little to know that, however, and his confidence had never been more shaken. And just when he thought he couldn’t handle another embarrassment...

One of the key takeaways: Stolen base success rate remains very high, but teams are attempting fewer stolen bases. But this isn't the 90s anyone. That bases-clearing dinger is hard to come by right now.

A line chart timeseries graph that shows stolen base attempts per opportunity, as well as the highest and lowest rate teams in the league. Since the rule changes in 2023, teams have become increasingly more selecting about stolen base attempts.

I think this graph represents the key detail: Working 1 extra pitch per AB can force teams into undesirable bullpen management on a regular basis. The problem is that averaging +1 pitcher per AB is a HUGE change in plate approach. Not an easy accomplishment.

A pair of area charts show the rates of bullpen usage in my Monte Carlo simulation. The team that works longer at bats (1 extra pitcher per at bat) is more frequently accessing long relievers in late innings.

This was probably the biggest realization for me -- the idea that we should be hunting blowout wins, no small-margin victories. Looking for 1-run game magicka is tantamount to playing hoopaloo with the wind. The effort is better redirected towards talent ingestion.

A trio of bar graphs showing the distribution of result margins among playoff contenders, .500 teams, and losing teams. The big takeaway is that good teams win by large margins, but everyone has about equal qnatities of 1-run games.

It's very rare to get a top tier #MLB hitter from someone who didn't crush minor league pitching. To quote Billy Beane from Moneyball: “If he’s a good hitter, then why doesn’t he hit good?” www.baseballprospectus.com/news/article...

A bar graph that shows the percentage of above average MLB hitters, grouped by their minor league OPS+. By far, they come from hitters with 130 OPS+ or better in the minors, and that group has produce a median 19 WARP.

It's a very optics-oriented day at @baseballprospectus.com this morning.

There are two headlines on the homepage about eyes and visibility.

I'm not saying it's inevitable, but it's the direction things are going: By 2030, the #Brewers' Brice Turang is going to break all of MLB's single season records. www.baseballprospectus.com/news/article...

But seriously, this is just my same plate approach in #MLB The Show.

Pitchers aren't adding velocity mid-season like they used to. Finding out why is as difficult as being sure it's happening at all. www.baseballprospectus.com/news/article...

A plot showing total velocity added per month. Colored lines represent individual seasons, 2008, 2013, 2019, and 2025. Pitchers in 2008 added about 0.6 mph by the season end. In 2025, that number was closer to 0.3 mph.

This was a terrible call. And I say we bring it back.

Over at least the past two game, the #Cubs have already been using the 1114 W Grace St location for paid parking.

The above plot shows Kikuchi's 2025 season (all batters). Yordan is interesting because, in his abbreviated 2025 season, the whole league pitched to him like they were channeling Kikuchi.

Bradley Woodrum@bradleywoodrum· Mar 25

Some players zig with the league zags. And some players have to be zigged around because they're so terrifying. I present: Yusei Kikuchi vs Yordan Alvarez. Zig meet zig. I had a lot of fun putting together the visuals for this one.

I'm old enough to remember the early days of PITCHf/x when we all collectively realized with a pained gasp that #MLB lefties had a vastly different strikezone than righty hitters. That "lefty strike" disappeared quickly (thank goodness!), but how many decades had it been there?!

A screenshot of the article that notes how umpires have improved their strike-calling accuracy by almost 6 percentage points since 2009.

Sweeper dotted down and away. No problem of Okamoto-san. He blapped it 103 mph over the CF wall. Wow!

A pitch plot showing the locations against Okamoto in the at bat. The final pitch is highlighted with a red arrow. It is a sweeper low and away in what is essentially a perfect locaiton.

A commentor named TDMOC asked how far Barrels need to slip in run value in order to be more like a Single in RV. A great question! And I should have included it on the original bar chart. In short, they've got a long way to fall. At the current rate of decline, I estimate circa the 2046 MLB season?

A 2015 to 2025 timeseries line chart that shows MLB home run run value (about 1.4 RV), doubles run value (about 0.8), and singles run value (about 0.5) as horizontal lines. A jagged black line representing Barrel run values start about at 0.9 and decline down to around the 0.8 mark where Doubles sit.

But there's got to be a better way to phrase this.

"Sure enough, Tillman gave Bush a Peanut Punch, knocking the ball out."

It's been 10 years since David Bowie died, and I still am deeply sad during my annual listening of this album. He lived an exceptionally good, long, successful life. An accomplished artistic career beyond any standard. But I'm greedy. I still wanted more. As he said, he couldn't give it all away.
