The play-index is a fantastic tool too, but you have to pay for an account to use it. Simply awesome.

[grall1126]

I looked at the play index and does anyone know what the difference is when paying for it? I am able to get to things by using it?

I click on the tabs on top and get information, I don't how the player index does more? Is it the comparison component?

You can get a list without the subscription, but the first ten names will be blanked out. I think you can get such lists at fangraphs.com for free as well, so that's something to keep in mind if you don't want to shell out. That feature is available under the "Leaders" tab. You can select any range of years you want, and see who the leaders were in whatever stat you want during those years.

Baseballsavant.mlb.com is also pretty good. Has a lot of visual stuff and highlights a few of player's top numbers and ranks them with other players in that year.

I like using baseballsavant for finding standard numbers, and using baseball-reference for sorting through league player statistics.

If you like incorrect stats, then Baseball Reference is your place. I went through their stats last year and over 9% of their stats on their player pages in current years(2015-2018) are incorrect. To tell if you are looking at good stats, you need to match up the player page stats to the split stats. It seems that they don't fix stats when notified either. I gave them a list and prove their stats were wrong and they never corrected them a year later. Too much checking to use this site for accurate results. Fangraph was a little better but a lot of wrong name duplicate players when I started reviewing them, so I gave up and that was just 2018 alone. Best stats come off the MLB.com player pages. It's a pain in the *ss but they seem to be the correct stats when reviewing everyone. I just wish that the MiLB.com site used the MLB.com Player Page.

How did you prove 9% were wrong? Examples?

[BaseballMan]

I know mlb.com does not recognize the National Association stats where i think Baseball reference and retrosheet does.

Retrosheet is the best for MLB stats history.


They add stats that were not tallied like BB and others the official records don't show. But they do make mistakes also, like Rob Mackowiak.

[Drstrangelove]

A single box score on BBRef could easily have 1,700 pieces of data. In the course of 4 seasons, that exceeds 16 million single pieces. In theory, that could be replicated for every player that played in that game. Plus, there's the summation of all those numbers along with calculations. I don't doubt they have some mistakes. I don't see how not.

I love when people ask me to prove things!


So here you go! (Sorry Admins I just had too!)


First thing I do is review every player on my spreadsheet. Since I know the count of players on my spreadsheet this gives me how many players I reviewed(That is my base number). I then cross match BR Stats on their profile page with MLBAM stats on the MLB.com page.(This includes minor leagues) Once I find a players stats are not matching on each site, I research the game logs of both sites to see where the error is. As you will see below, I detail every non matching stat and the cause of the error. Sometimes I don't even have to leave BR to find out there is an error. The player page stats don't match up with the game logs and splits. Now since I reported this almost 18 months ago, there has not been any changes in the players I reexamined. Now your going to say, no one puts this much time into going through stats of every player in the last 5 years, well there you would be wrong. Many people can vouch for me that I do this for a living and more. I do have a rep in this area, so I would not be blowing smoke if not true.Here are some examples as asked for so you can see for yourselves. Sorry No Pics.


Reynin Reynoso DSL Royals 2017 Game on 8/17 was cancelled and stats removed. Game Log doesn’t reflect this. Otherwise matches MLBAM. PA on Register should be 193 not 192. After removal of cancelled game. Per your Game Log and MLBAM.

Carlos Pacheco DSL Cubs1 2017 Batting Register shows 67 Games and 280 PA. MLBAM shows 67 Games 281 PA. Your Game Log shows 68 Games. If you remove the cancelled game for the game log.( Aug17 vs. DSL Astros Orange, Canceled: Rain). The Game Log will match MLBAM stats. Meaning the Batting Register’s PA are incorrect.

Pedro Castillo DSL PIT 2017 PA shows 146 for Batting Register, Game Log shows 149 (Note:AUG 17 vs. DSL Rangers1, Canceled: Rain-148) MLBAM shows 147. Have no idea who is correct but MLBAM and Game Logs usually match but Game Log shows 4AB on 8/5 Game while MLB shows 3AB. If 3 was correct like I believe it is after reviewing box score. 3AB and 1BB he couldn’t reach 5PA. This would mean MLBAM would match Game Logs and Splits at 147.
Samuel Inoa DSL PIT 2017 Batting Register shows 150 PA, the Game Logs and Splits match MLBAM at 151.
Victor Garcia DSL STL 2017 Batting Register shows 106 PA. Game Logs and Batting Splits along with MLBAM show 107PA.

The 6/5 Game he officially had no PA because he took over the AB for Sanchez. a-Struck out for Sanchez, D in the 7th. With this removal his PA should be 108 the same as MLBAM.

I don't think Markus wants me to put up ALL of BR errors on his site.
So I gave you a few and what to look for. The only other way is to have someone review it themselves and then if it is not you, are you are still going to question it?


I've done the research and even let them know the errors and they (Including Sean) didn't change anything, it's not their data.


You can question it all you want but I do this on BR, Fangraph and MLBAM especially. If I was wrong they would of let me know.



I have more things changed on Milb and MLB.com in a week than the top poster here can post in a week. I am known by all 30 Top PR Executives in MLB. Minor League Presidents send me League Schedules. I am very well known for doing these things, along with reviewing signing dates and getting people put on rosters on MiLB and sometimes MLB (but not so much). That is my resume and I'm well respected for finding errors in stats or biographies



If you want more proof spend the time and audit it yourself.


But after you wasted that time, it would be nice if you confirmed it and not ran away.

[Drstrangelove]

At most, I see your point that the Dominican Summer League might have identifiable differences in one database to another database. But as I mentioned before, in MLB there are 4 million numbers per year that could be wrong. When you add in all the other leagues, that number increases dramatically. Of course, anyone can find differences when they are comparing two independently maintained real time databases with tens of millions of numbers. That should be expected. Especially if they use different sources.

Even one quarter of 1% of differences could work out to 100,000. But that doesn't prove the error is in BBRef. It proves there's an error somewhere. And even if it was all in BBRef, it doesn't prove the total is 9%.

[Drstrangelove]

duplicate posting

[Benchmark]

You sound like Dr. Theo? I'm guessing that is who you are.

If so, yes you have flaws in your system. I didn't say the complete BR was 9% and you seem to know a lot about how the database is put together.

Keep confusing people with 4 million calculations but you have a system to check it! Why not check it and let us know since if you are Dr. Theo then you should let the people know they are YOUR STATS and that is why you are declaring it not possible. Please explain your connection to BR or this database since you seem very knowledgeable how he puts it together.

If you aren't I apologize but you are pushing this a little too much not to be invested and the board should know if your connected to this in anyway.

I've done the research, that was my calculation on my database, now you do it and prove me right. I stand by my findings and I am not associated with BR or any other stat company.

You may be pleased to see this post from Markus's AMA.

[tward13]

Are all the errors you've documented from the DSL and VSL? Are there the same errors with MLB stats?

[BirdWatcher]

Is it just me or is this thread getting a bit unhinged?
