Schedule anomaly
Wed, 16 Sep 2020 (by RotoGuru)

Today's SF @ Sea game was postponed, due to poor air quality in Seattle. It has been replaced by a game in SF instead. However, since Seattle is still the listed home team, my schedule feed thinks the same game is postponed and being played - which is technically correct, since both games are listed as SF @ Sea.

I have updated the weather dashboard to show the game in SF. Some reporting will probably show the game as postponed, at least until it starts being played. So disregard the postponement indicator.

Just another "charm" of the 2020 season!

Any Laura Losses Lingering?
Thu, 27 Aug 2020 (by RotoGuru)

Hurricane Laura knocked my server offline for awhile last night. (It's in the Dallas area.) I believe all functionality has now been restored. I've attempted to rerun all processes that failed overnight, and hope that I have remembered them all. If you see anything that appears to be missing or off-kilter, please let me know.

As of 9am ET Thursday morning, Yahoo has not posted any daily contests for MLB or NBA for today, so I'm guessing their operations were knocked for a loop last night as well.

Unmasking ADI & VMI values
Tue, 25 Aug 2020 (by RotoGuru)

Going forward, in order to see the current day values for ADI and VMI, you'll need to have an active membership at

If the values are not appearing on the Weather Dashboard, there is a validation link in the notes just above the table data.

If the values are not appearing in the master file, then append your email address to the URL, as illustrated here:

Transporter Malfunction?
Mon, 17 Aug 2020 (by RotoGuru)

My systems are not configured to properly recognize the correct gametimes or venues for doubleheaders when the home and visiting teams switch. For example, today's Cardinals vs Cubs doubleheader officially lists the opener as St. Louis @ Chicago, and the nightcap as Chicago @ St. Louis. But both games are played at Wrigley field. And some of my systems think that both games are to start at the same time.

Maybe I'll eventually figure out a way to compensate. But for now, just be aware of the likely discrepancies in those situations.

Christmas in August
Sat, 15 Aug 2020 (by RotoGuru)

After some thought, I've decided not to charge anything for the "premium" data related to the 2020 MLB season. The season is so short, and there are many anomalies in schedules, postponements, and cancellations that - quite frankly - are giving some of my programs fits in interpreting. And of course, there is a non-negligible chance that the season will all come crashing down at some point. So, 2020 is on me.

There is one weather-related exception. Beginning on August 24, current day ADI and VMI values will only be displayed if you have a valid membership at This applies to the weather dashboard, and also to the 2020 master data file.

Premium data for prior seasons will continue to cost you, however. Subscription details for seasons from 2015-2019 are HERE.

Off the grid
Wed, 05 Aug 2020 (by RotoGuru)

My home and office neighborhood was hit hard by the tropical storm on Tuesday evening. I lost power, and also lost my internet connection. The local damage is severe enough that it's likely to take several days for power to be restored, and then I have no idea when internet service might be restored. So I'm relying on my cell phone for data connection at the moment. There is so much demand for cell data right now, that most of the day I'm unable to get anything through - not even email flows easily. I had to drive to a remote location just to find a cell signal ample to post this message.

So for the time being, my ability to do any troubleshooting is virtually nil. Fortunately, the server is in a remote location, and is unimpacted. But I'm not really able to connect with my server for the time being. Thanks for your patience.

Befuddling postponements
Wed, 29 Jul 2020 (by RotoGuru)

Some of my systems are a bit befuddled about some of today's postponements. In particular, the programs don't really know how to interpret schedules for the Orioles and Yankees - who each have a canceled game as well as a scheduled game against each other. I think it will all sort itself out, but you may see some unusual listings in some reporting formats. Deal with it.

Bullpen report enhancements
Sun, 26 Jul 2020 (by RotoGuru)

If you've pulled up the daily bullpen report this season, you may have noticed some changes from prior years.

First, all pitchers are now included, including starters. With many teams now using a reliever as an "opening pitcher", excluding starters created some anomalous omissions. So I avoided the issue by simply tracking all pitchers.

Also, the lookback period can now be expanded to 14 days. This option provides a deeper look at usage (and patterns) for all relievers.

Hopefully, these enhancements prove to be useful.

De-Glitching continues...
Fri, 24 Jul 2020 (by RotoGuru)

I've fixed a number of glitches in the past 24 hours, and I think everything is working as expected. Active links for all pages and reports can be found in the menu bar above.

If you see something that looks off, please say something.

2020 Master File
Thu, 23 Jul 2020 (by RotoGuru)

The 2020 Master file is up.
Here's the link:

A few notes:

  • For the first few days, the file may be updated late, and some info may be slow to populate. Hopefully, by the weekend, all data conduits will be fully activated.
  • The file will be free for the first few weeks. At some time in early August, subscription terms will be announced, and subscriptions will be offered.
  • Remember that each MLB season is offered under a separate subscription. Data for prior seasons can still be purchased. See this page for information in accessing master file data for prior seasons.

Looks like this is going to happen...
Wed, 22 Jul 2020 (by RotoGuru)

Daily Batter vs Pitcher reports are now active, and the Weather Dashboard now has forecast data for opening day (7/23). I hope to have a preliminary 2020 master file ready by the morning of July 23. Sortable Stats reporting is still inactive. Hopefully, those reports will also be up by opening day. Umpire and Bullpen reporting will not begin until Friday.

I rely on users to report apparent glitches in data or formatting. Several of you have already helped me identify and correct some minor issues. With any luck, eveything should be ship-shape by the weekend.

Dusting off the cobwebs
Tue, 14 Jul 2020 (by RotoGuru)

At this point, it looks like the MLB season will be starting on July 23. How long we go before the first interruption is anyone's guess, but at this point, I'm gearing up to provide the usual data and reports.

The schedule is out and posted. The rest of the pages should begin populating with data as we approach opening day. Don't expect to see much until July 22, but I'm hoping that most of the reporting should be available by July 23.

The master data file for 2020 will be free for the first few weeks before subscriptions are offered. I have not yet figured out the exact timing or price; stay tuned.

Into hibernation
Thu, 31 Oct 2019 (by RotoGuru)

After a very entertaining World Series, now goes into hibernation for the off-season. Thanks for your support during 2019. Hope to see you back in 2020.
