The Game's Community Ratings Calculator

Re: The Game's Community Ratings Calculator

Thanks to statdude for all the work he's doing testing this out. You are helping immensely with improving this calc.

So here's the deal. Steven Souza has now been fixed with Steven Souza Jr. giving you the correct info. He probably won't be the last guy we find either, so skip them for the time being and please post them here so I can get it fixed.

Second in regards to Mikie Mahtouk and others like him, your finding has caused me to change how I'm choosing whether to use their minor league stats or major league stats. The first file was basing it off total at bats which you can see in row 5 above each year. What I've now done is changed it to at bats vs l and at bats vs r. So Mikie Mahtouk is now having all his calculations based on his minor league stats.

Here's how it happened. Mikie Mahtouk had 37 ABs vs R and 68 ABs vs L. This got him above my minimum at bats of 100, but it really wasn't enough data to support using his SMALL major league statistics. He produced incredibly well when he played in 2015, but it was in a small number of at bats.

He now gets a career 51 vs R and 55 vs L, a 44 and 47 for 2015, with weighted ratings of 49 and 53. Power is now lowered significantly too.

So here's a question for the community. Per year, what do you think is the minimum number of at bats a player should have vs R and vs L to justify using his MLB stats. I need this by year and for career. Currently, it's set at 100 ABs across the board, but I feel this needs to be tweaked.

Thoughts? Thanks again statdude!

Oh, and updated version will be posted within an hour or 2.

I would think 100 AB's would be about right myself. Are you wanting/considering to make it more or less than 100? I don't think I would want it to be under the 100 AB mark but that's just me. Thanks!

Re: The Game's Community Ratings Calculator

Here is an article from Fangraphs that show when certain stats stabilize. This can be a starting point. This is also dependent of having 2000 PAs total.

But then, according to this article (http://www.fangraphs.com/library/principles/split/), it states that you need about 1,000 PA per hand (L and R).

Note: This is for a career.

Well, I'm undecided. Keep in mind it's 100 ABs vs R and 100 ABs vs L. So 200 total ABs. Maybe 75 a piece per year and 150 a piece for career? Something like that? If they are less than the 75 or 150, it would then revert to rating them based on their minor league stats.

Re: The Game's Community Ratings Calculator

I think you should stick with a 100 if not more on both side. But I would scale the stats back if he is on a tear . TREVOR STORY, for example. Great program and I cannot begin to think of the amount of time and hard work you have put into this Program, Thank YOU.

That's awesome. I feel 1,000 per hand for career would be a little much and a ton of guys wouldn't reach that metric. But I definitely might be using numbers too low.

As an example, Jose Altuve doesn't even have 1,000 PA vs L, but we all basically know what he can do with the bat, especially against lefties. 500 maybe? 250?

Lastly, since you mention PA, I wonder if I should be using PA instead of ABs. Thoughts?

Re: The Game's Community Ratings Calculator

Since some people have asked how I calculate the weighted stats, here's how.

55% to most recent season played, 30% to season prior to that, and 15% to career numbers. This is only changed when a guy has only two years of available data, which then I give 75% to most recent season and 25% to career.

Does that make sense?

No way for me to scale it back just based on a tear. Mikie Mahtook is a really good example, although I think Trevor Story will be MUCH better. Mahtook in limited ABs had some incredible numbers. Almost a .300 average against righties and lefties, and some even more ridiculous power numbers with 57 HR/550 ABs against lefties and 30HR/550 ABs against righties. In limited time, dude looked like a stud. But I don't think ANYONE thinks that is even close to sustainable.

If it's me rating it, I take the calculation for Story and bump contact and power up maybe 5 points per rating, but that's about it.

It depends, imo.

If you're counting stuff for when contact is made, then I would go (AB - K), i.e. almost like the BABIP formula, or maybe (PA - K - BB) if you don't mind counting SH and SF (and for hit type, I might would go with Hits since you only want the safe hits - no need to count BIP outs if you're trying to see how often someone's hits go for doubles or HR, for example).

If you're looking at things like walks and strikeouts (like for rating PVis or Disc), then PAs works because you need the raw event. ABs strips walks out, which is what you'd be trying to count for walk rate (BB/PA). BB/AB is taking walks and dividing it by something that removes walks.

I don't know what all is being calculated - just showed up in the thread today since the title happened to be showing for the Rosters forum and I got curious and I haven't had the chance to grab the file and play with it, but this kind of thing interests me, even if I don't usually play with rerates (due to draftees).

Oh. I thought you meant 100 AB's total combined from both sides of the plate. What you have listed there seems fine to me then.

Game, forgive me for not thinking LOL, you are working with a calculator and scale back or whatever changes I think is on me.

Re: The Game's Community Ratings Calculator

Use both majors and minors stats combined. That's what I do with all of my players, including players that had a couple rehab games or whatever. Majors plus minors with MLE. Whatever's the total is what goes into attributes.

Re: The Game's Community Ratings Calculator

Guys you don't need 2000 PA or whatever. You just use, say, 150 PA of what has actually happened, and add in 1850 PA of a comparable average as regression.

There's one problem with that. What my calculator does is scale back minor league stats based on their current level. Some of my ratings do combine minor league stats with major leagues, such as steals, base running ability, and strikeouts. But other stats like contact, plate discipline, vision, walks (pitcher), and a few others can be WAY different between minor leagues and major leagues. These are stats where a guy might excel in the minors but do nothing even close in the majors.

If a guy has power in the minors, he usually can have power in the majors. If a guy strikes a lot of guys out with power pitches, he usually can strike out a lot of guys in the majors. But that doesn't mean he's going to hit a lot in the majors (contact) or keep from getting hit in the majors. That's just my take from years of being a baseball stats dork.
