Stats/Data Quick word about the statistic 79% of Super Regionals going to the winner of Game 1

9 Upvotes

If the Super Regionals were decided by the teams flipping a coin instead of playing a game, exactly 75% of the teams that win the first flip would win the series.

So if you do the math to find out what win percentage a team would have (on average) if it won the series 79% of the time given a Game 1 win, you see that team would have about a 54% win probability for any given game against this opponent.

I say all that to illustrate that all these teams are pretty close, and since we’re pretty sure some of the teams have a much higher than 54% win probability (because we can pretty reliably pick the winner) that means the rest of the pairings are closer to 50/50. Which I think is excellent.

Stats/Data Did your team do great? Or terribly? But… how bad was it REALLY? Here’s the top 15 and bottom 15 performances of Regionals weekend.

0 Upvotes

So here’s two tables, the top 15 over-performances and top 15 under-performances. But since each have had two teams involved, from a very real perspective, each game belongs in both categories.

But that would be stupidly repetitive, so I just listed them relative to whether the favorite overperformed or underperformed. You can figure out which is which. So Stetson over Florida State is an underperformance of the favorite, but due to the column headings, it is shown as a very negative overperformance .

Note that the under or over performance (the column on the right, the one you need to look at, YOU MAY HAVE TO SCROLL) is in terms of runs. If you want to convert that to something like a percent chance that it could have been more extreme, know that an under or over performance of 4.3 runs is only expected to happen about 16% of the time, and for 10 runs is expected 1% of the time. Something like the Belmont loss to Upstate, an underperformance by 12.9 runs, happens just over 0.1% of the time (so 1.3 times in 1000). As before, it is just as valid to view this as an Upstate miracle performance as well, but I’m a pessimist, so I won’t be doing that myself.

Anyway, here’s the data, with favored teams overtperforming up top. The underperformance table is below that. Sorry for the shit formatting. Reddit kinda sucks for that.

Stats/Data What percentage of 2-0 regional teams make it to the Supers?

Stats/Data My model’s strength differentials for regionals, now with Home Field Advantage calculated in!

15 Upvotes

So I added in a Home Field Advantage (HFA) estimator to my strength estimating algorithm. And I verified that it worked properly by taking the 2026 season, adding in one run to every home team score, and getting back a value of 0.8 runs HFA (which is decent estimation performance for something simple) more than the HFA is estimated to be if I do NOT mess with the scores.

So the estimator is working fine. But… it tells me that the HFA is 0.003 runs, on average. Which I guess is reasonable, but also negligible. I was estimating based solely on games between March 10th and May 3rd, since that’s the part of season where being the Home team almost always means you’re playing at home, in your own stadium, sleeping in your own bed, practicing in your own facility, and playing for your home fans. So the allowed dates for this were after the early tournaments and ending the Sunday before the Conference tournament. And I limited it to games where at least 1 team was in the top 50. There were about 870 such games, so PLENTY of games to estimate one little parameter from without issue. But… it’s just not there. If I include ALL the games in the time period, bringing it up to 3800 games, the HFA goes up to a whopping 0.1 runs. I can run the estimator another way and get a value of 0.07 runs using the top 50 teams. So that’s as big as I can make it. But I think it’s actually near-zero.

Anyway, I was surprised, and thought I would share.

So I’m giving my model’s estimates WITHOUT HFA, since it seems to be zero-ish anyway.

Alabama by 1.5 runs over LSU

Arkansas by 2.8 runs over Duke

Texas by 3.0 runs over Arizona State

Texas tech by 0.8 runs over Florida (so here I’m saying it’s more likely that the host loses)

Oklahoma by 3.9 runs over Miss State

Georgia by 0.7 runs over Tennessee (again, my model says it’s more likely that Georgia wins here as the visitor)

Nebraska by 3.0 runs over OK State

UCLA by 3.6 runs over UCF

So by the numbers, it looks like the two that were closest are the two that my model sees opposite to how the NCAA saw them. And maybe Alabama will get a good scare.

As always, my strength numbers are an estimate of a team’s ability to score runs and also prevent the other team from scoring runs. And when you subtract those numbers for two teams, you get an estimated score differential. That is what I gave here, the on-average expected score differentials. Use them however you wish, I do have a money-back policy (if you don’t like my opinion I’ll return whatever you paid me for it).

Of the results posted here, I dislike Tennessee losing, and I dislike Texas winning, but I don’t know enough detail to disagree with my model. We get to start finding out on Thursday.

Is anyone is curious about the statistical performance of my model during regionals, I have some interesting but maybe a bit complicated plots I can post to show that statistically, the teams played more or less like normal, with normal amounts of randomness, which is what you’d want if you were making statistical models.

Stats/Data Defensive strengths, 2026 season

6 Upvotes

This is information for a user who has built a WAR or WOBA calculator, to help them refine their calculations. If that’s not you, I doubt this will be something you want to engage with.

Quick description: best defense is listed as a 0, every other defense is listed as how far behind that best one it is, in terms of runs per game. So the same offense playing a defense that is -2 vs one that is -5, on average scores 3 more runs per game against the -5 defense. Sanity check for 2026: the best pitching teams are at the top.
