Not sure if I read this when first posted, but the defensive stats mentioned by Mejdal include the following:

infielders:

where the ball was hit, where the infielder was standing, the time the infielder had to get to the ball, the time it took to accelerate, the time to get to the ball, the time to exchange the ball, the time to release it, the time it took the ball to get to first base

Information on State cast leaderboards: catcher framing, outfielder jump, catch probability, 

Statcast OF Info: outfielder jump, reactions in burst, route efficiency

One starts to get the idea that all functions (skills) involved in a play are measured and yield averages and peak results.

All great and very interesting stuff.

As I mentioned last summer, when I spoke to an Aberdeen pitcher during a rainout, the report given to the pitcher the day after pitching has 16 stats on every pitch thrown.

I have every confidence that our front office is building a state of the art analytics department and that it will help close the gap with a good portion of the rest of the league evaluates and trains players.

And the key word is "building". It takes time.

I think this is probably Sabermetrics 101 for these guys.   I don’t think Sig is giving away state secrets here.

I read this earlier and forgot to post. Very good story.  Raises a ton of questions about the defensive metrics.

I know a guy who works in the analytics department of MLB.   He says the department now has defensive metrics for infielders akin to what they’re doing in the outfield, but they are still working out the kinks before making them public.    Can’t wait.

Didn’t Zobrist break the WAR system because he was playing all over the IF, and with shifting was putting up good dWAR with TB?  He never had a positive dWAR after leaving there.

War doesn't work anymore. If it really ever did. But they are going to fix it. They will.

He broke UZR because of his shifting.  IIRC they ended up taking out plays that are fielded more than a certain distance away from the usual starting position for a given fielder so Zobrist and a few others wouldn’t get OOZ credit for balls hit in the RF gap as a 3B.

      Jackson Holliday 2024

      By Sports Guy · Posted

      Like I said the other day, it would be nice to hear from some scouts, the org or whoever about all the walks, lack of power, lack of BA, etc…is he tweaking things? Is the elbow bothering him to where he can’t drive the ball? Is he getting nothing to hit?     I’m surprised someone from the Banner hasn’t gotten into this because it’s obviously a big story and one that should be reported on.

      One thing to note is that Jackson made swing tweaks his first three weeks back in Norfolk but then abandoned them because they “didn’t feel great”. From this Baltimore Banner article:  “Earlier, as he fiddled, Holliday felt he was “surviving” and “didn’t feel great” about where his swing was, even though he produced at the Triple-A level upon his return. That has since changed. Over the last two weeks, particularly, Holliday’s return to the mechanics he’s more familiar with has helped him get back on track.” His contact rate really dropped off when he reverted back to his familiar mechanics. I worry that he gave up on the changes too soon. First three weeks back vs. after (includes tracked pitches and non-bunts)   PAs    K%           wOBA  xwOBA whiff % 4/27-5/18 91 19.8% .366 .349 21.6% 5/19-7/2 118 28.8% .392 .337 32.1%     PAs    EV      hard hit % barrel/PA 4/27-5/18 91 89.5 44.4% 4.4% 5/19-7/2 118 89.8 44.6% 4.2%

      John Smoltz on why pitchers are "breaking" and what we should do about it..

      Sure. And his ligaments would have likely snapped, and he'd have put that college degree to good use instead of being a ballplayer. Or he would have thrown at 90% like most everyone else and topped out with Cedar Rapids in the Three-I League.

      Let's say you allow the sticky stuff. The guys whose sweeper breaks 10" might now see it break 12". You think they're going to grip the ball more loosely, throw with a little less effort, get hurt less, and be content with a 10" sweeper?  No! They're going to grip the hell out of the ball and use the sticky stuff and try to get a 15" sweeper. And they'll keep getting hurt just as much. It couldn't be more clear that almost every pitcher and every coach and every team chooses the high-risk, high-reward path. You can't put the genie back in the bottle.

      I guarantee you that if Christy could only get guys out by using his best stuff he would have.

      I'm going to guess that in the olden days there was a weeding out that happened before most kids played an organized baseball game. Many, many kids played baseball all day long in the summer, and many, many of them tore up their elbow or shoulder at 11 or 13 or whatever and never pitched on a high school or other team. And nobody was Drivelining anyone. Part of the philosophy of pitching was you don't throw as hard as you possibly can because it hurts and you'll ruin your arm. A few people got away with throwing near max effort, but most couldn't. And there was a very stong stigma to coming out of a game, so pitchers knew they'd be shamed and mocked if they threw until it really hurt and had to come out. In the 1910's Christy Mathewson (or a ghostwriter) wrote Pitching in a Pinch, where he explicitly said that using your best stuff except when you really needed to was stupid.  Smoltz is a guy who idiotically venerates the past, making the era where he came up into some kind of golden nirvana. But, he is right that the driving factor in injuries today is that everyone throws at 110% of rated capacity all the time. It's just a matter of time until something tears.  The problem is that there is no simple solution, since throwing at 110% is simply more effective than throwing at 90%. 90% gets you (essentially) limitless innings. But 110% makes your ERA half a run or a run lower (numbers made up for illustration). And it couldn't be more clear that when $millions and wins are on the line, essentially everyone picks the lower ERA over the more innings. An average MLB pitcher has an ERA in the mid-4s. If he backs it off to 90% so he can pitch into the 8th or 9th, he'll likely have an ERA in the mid-5s, which puts him in AAA. The difference between pacing and pitching until it breaks is often the difference between $7M a year and $70k a year.
