    I couldn’t be happier to announce that my DFS MLB projection system, THE BAT, is launching today here at RotoGrinders! If you’ve used THE BAT over the past couple years, there’s probably not much more that I need to tell you; you know how much it can help your DFS game. If you haven’t heard of it yet, I’d like to think you’ll be happy you have now.

    What is THE BAT?

    I’ve developed THE BAT over the past six years and close to ten thousand hours, using skills and methods I’ve developed from my time in the sabermetric community working with some of the best baseball minds in the world, many of whom are now making decisions for Major League clubs. Skills and methods that help set THE BAT apart from your run-of-the-mill Vegas or wOBA model. Vegas and wOBA are shortcuts, plain and simple, and any model that relies on them will give you results and lineups that are shortcuts and, therefore, suboptimal. THE BAT goes well beyond that, incorporating everything wOBA or Vegas can tell you but in a more complex way and with plenty of layers and features on top. And it works with RotoGrinders’ Lineup Builder, helping you build your ideal lineups for both cash games and GPPs.

    What Goes Into THE BAT?

    While I was developing my system, the code name I used for it was BATMAN, named after a certain caped crusader who 1) Is awesome, like I intended my system to be, and 2) Uses all sorts of gadgets to get the job done, which is the perfect analogy for my system. As far as I can tell, THE BAT takes into account more factors and has more features than any other system out there. You can get more details here, but to list a few, every single day THE BAT considers:

    • Opposing Hitter/Pitcher
    • Ballpark
    • Weather
    • Umpire
    • Catcher Throwing, Intimidation, and Framing
    • Bullpen
    • League
    • Home Field Advantage
    • Platoon Splits (Hitter/Pitcher/Park/Umpire/Catcher)
    • Role
    • Lineup Position
    • Quality of Surrounding Lineup
    • And more, explained further in THE BAT FAQ

    And THE BAT doesn’t just take what a player has done at face value. There’s a big difference between past performance and expected performance, and that’s why each one of these factors has its own underlying projection system so that THE BAT can have the best estimate of how well everyone and everything should perform going forward.

    What’s New for 2016?

    For those who’ve used THE BAT before, I hope you’ll be as excited as I am for some of the features that are new for 2016. While plenty of smaller upgrades have been made, the two biggest ones are the inclusion of weather data (temperature, wind, humidity, and several others that impact on-field performance) and minor league data.

    So when this year’s version of Carlos Correa gets called up, THE BAT will already have an exact projection for how good he is based on his entire professional career. Along with minor league data is Asian player data. With a record number of Asian imports this winter, DFS players will quickly realize they need to know their Byung Ho Parks (potential cleanup hitter for Minnesota) from their Kenta Maedas (Dodgers number-two starter). While other systems wait for these guys to accrue MLB stats or make a conservative initial guess, THE BAT is already taking into account their body of work Japan and Korea and translating it to the context of Major League Baseball.

    Wrigley Wind: No More Guesswork

    One of the most exciting parts of my new weather formulas is eliminating the guesswork on days when there is wind blowing in Wrigley. We all know wind can make a difference, especially in Wrigley, but how much of a difference? Instead of guessing how many guys to try and squeeze into your lineup, THE BAT will weigh the exact importance of the wind in conjunction with every other factor for the game and help you make the best decision possible.

    Why RotoGrinders?

    I debated taking THE BAT off the market this year to just use for my own play, but when it came down to it, I just love the DFS community. I love helping and teaching. That was why I started doing this in the first place, and that was one of the driving factors behind my decision to join RotoGrinders. This site and these forums are a community, and I’m looking forward to being a part of it and helping you all at DFS through my articles, expert chats, radio spots, GrindersLive appearances, and by making my projection system available.

    How Do I Buy THE BAT?

    Simply head over to this page and follow the instructions, to purchase THE BAT! – If you have any questions, please post them here, or feel free to email TheBAT@RotoGrinders.com at anytime. I’m happy to answer any questions you have about myself, THE BAT, or DFS in general.

    I wish you the best of luck this season! Just four days until Opening Day!

    I purchased The Bat on Friday. I’m a small daily player and more of an Action Junkie than a studier of stats. Trust me, spending $150 that is not a deposit is pretty out of character for me. I do love and follow baseball though, so it made the purchase a bit easier because I would not purchase a NBA equivalent. Anyway, yesterday I entered a 14 person $27 Satellite and won a $333 entry using The Bat. I’ve done OK in other time slates using The Bat, maybe a few bucks down because I’m a sucker for Moon Shots. However, facts are facts, it took two days for me to already justify the purchase. I just wanted to pass on my first experience using The Bat. Now, I almost feel selfish that I do not want others to take the leap so that I have an edge, haha. Actually, I have no problems sharing with you fine folks. All the best.

    what is your overall opinion of this product. See several post referring to some problems. Do you feel this product is suited to Fanduel tournaments?

    Disappointed, but cautiously optimistic these issues get worked out soon.

    I apologize for the issues this morning, guys, and for not resolving them sooner. I have to import our probable pitchers feed manually, and I forgot to do so this morning traveling home from Bootcamp. We’re setting up the automation process for probable pitchers this week, and we’ve put additional safeguards in place so that I receive alerts if these ever don’t match up with what is on the RotoGrinders side. Normally I’d notice myself, but I didn’t play today with the travel passing through restricted states.

    Here is what I want to know. I purchased the Bat today 15 or 20 min before 1:05 roster lock. Didn’t have time to do any research so I just hit the Bats optimal lineup on grinders lineup builder. What came up was the exact lineup as grinders free lineup builder. But here’s the kicker. It was loaded with players from the Bal vs Tex game that had been postponed hours before.

    How can you sell this thing saying you take weather into consideration and you have players from a postponed game in the lineup you spit out. And if you are not even getting something that simple right how are we to trust that all the other metrics you are claiming you are even using. Please help me out here because I am feeling kind of skeptical right now.

    It defaults each day to the RG projections. You have to click on LOAD BAT at the top in order for the BAT projections to come up.

    I have noticed that sometimes players outside game slates as well as players excluded creep into the rosters…my advise would be to click on the teams/games you want to avoid in the filter. I do this a couple of times to make sure they are not loaded into the Lineup Builder. I don’t think this is a BAT issue, but a Lineup builder issue. As with anything, always double and triple check to be on the safe side.

    I did click on load Bat at the top and still got the same lineup. I did manually exclude the game and got a lineup without that game of course but my question is still the same. We are sold a product here that said weather is one of the metrics. If they don’t even know it’s raining how do they know there is a 20 mph wind in from center field. Can I trust things like catcher framing pitch’s or umpire data? IMO this is kind of a big deal. Hopefully Derek will address these concerns.

    How long can The BAT be used before the refund window is closed? This was not addressed. It’s easy to say, “you can be refunded, if you are not happy”. But that could mean 90 days, 60 days, 30 days, or 1 day. I’m curious as to how this works, so I am asking.

    The refund policy is listed here: https://rotogrinders.com/pages/premium-subscriptions-refund-policy-1222042

    THE BAT

    If for any reason you are not satisfied with THE BAT and you’d like a refund, we offer a full refund within 5 days of your purchase.
    Refund requests made after the 5 day full refund period, and within 15 days of initial sign-up will receive a prorated refund of your initial purchase.
    Refund request made after 15 days are not eligible for a refund, with the exception of state specific DFS restrictions. In the case of your state restricting DFS play, you will be eligible for a prorated refund.”

    I think Majorrock hit on why you got the same lineup, if it’s using the RG projections. If you find that happening again, please send an email to support and someone will be able to help you, as that’s a Lineup Builder issue.

    In terms of weather, the system takes into account the aspects of weather that affect on-field performance — temperature, wind, etc. — but we need to remember that just like anything else, this is a tool, not gospel. As several users have mentioned on this thread, it still requires a bit of user interaction and research. That’s why all of the customization options are there within Lineup Builder. RotoGrinders has a weather page, Kevin Roth gives out great reports, so if a game looks like it may get rained out or is announced as being rained out, the user needs to decide what to do with those players himself. The product can only work within the constructs it’s given, and as the weather reports it uses don’t say anything about whether a game has been cancelled, the system can’t know that it has been; that part is up to the user. The way the system is designed is to project performance under the assumption that the game will play. If the game doesn’t play or has a chance not to play, then the user needs to interact with the product and adjust accordingly. For those games, in the Lineup Builder, you just click the team logos and those players that you deem too risky or have been rained out will be removed.

    Hi Derek,

    Are you intending on adding filter by team capability to the BAT?

    Thanks

    Thanks for the reply. Of course I cancelled that game out of my lineups. My point is how can your system take any weather into account if it can’t know what it is now not hours ago. That game was postponed hours prior to first pitch.. How far in advance are you getting this weather data and using it in your calculations? 2hr 5hr 10hr? It wouldn’t be a big deal if that wasn’t a pretty big part of your pitch. I just want to know how much of what you are projecting I can count on.

    Daily baseball data has all the weather for every game. It’s one of the first places I go when doing my research for the day. I read Roth, I look at radar, I do the research and that’s my point. I was very surprised when the first thing I saw when I clicked on optimal lineup 3 or 4 players from a rained out game after just dishing out $150 bucks.

    Anyway, it’s a tool, Maybe I just signed up on the wrong day. This and all the other problems just really make me wonder wtf. I don’t expect to be using optimal lineups set by the optimizer very often. Today was just one of those days I didn’t have time to do the research and decided to give it a shot.

    Will withhold judgement for a bit longer and see how it works out. But you know what they say about first impressions and this one was not good.

    Right, like I said, it’s using a weather feed, but the weather feed is from a weather service and isn’t connected at all to the games themselves. The feed may tell the system that there’s a 90% chance of rain in Texas, but the weather feed itself can’t tell the system that the game has been postponed. That’s a subjective decision the baseball teams make and separate entirely from the weather feed. If you go to Weather.com or any other weather site and look for the weather in New York, it’ll tell you that there’s an X% chance of rain but not that the Yankees game has been cancelled because of it. The system projects what will happen on the field if the game plays, and it’s up to the user to do the additional research about whether the game might actually play or not.

    I know you have a lot of feature requests and bug fixes that you guys are currently working on. I want to chime in again and say that I think anything you can do to add some transparency for the user would be greatly appreciated. This is especially true while there are a few bugs to work out. A “last updated” time, list of teams currently in the projections, a weather column so we know what forecast you are using, etc would all be appreciated and make the product more dependable for us who have purchased it. Thanks.

    I agree that the time-stamp for latest projection update like is done for NBA is kind of a big deal.

    Also would be fantastic if players in games already started would disappear… I know we can delete the games from the builder, but when in “the bat” it’s a lot of clutter especially when is a split slate with 4-5 or more early games.

  • xdan3220

    I’ve been using this for about a week and just have a few questions that I can’t seem to figure out on my own:

    1) Is there any way (or will there be a way) to filter out early games from the projections, frustrating when I’m playing the main slate and see something I like in the projections click over to my lineup and realize I can’t use that player?

    2) The listed WOBA, BA, SLG for the hitters are those based on last season, career, only against the handedness of the pitcher they are facing that day? I just don’t know what those stats exactly represent

    3) Any chance we can get some additional info on Umpires? I like that they are considered but I don’t know which are considered good for pitchers or good for hitters even something as simple as green/yellow/red on them if you don’t want to give away the info just so we know which way they lean.

  • Gfry3

    So I am 1 day in and yesterday was not the best, seemed like ALL THE WHITE SOX and well that didn’t work out at all ha. But its one day, so we will try again.

    My question is it shows $/PT and says the higher the number the better the value. That is EXACTLY OPPOSITE of what you mean correct? For example Pineda is 7.7k as is Teheran, without giving much away Pineda is projected for higher points Teheran and thus has a LOWER $/PT, but your column heading says “the higher the number the better the value” That is a large mistake in my opinion given some people will sort that column. I would rather a guy get 5000 fp at 5k for 1$/Pt not the reverse.

    Just making sure I am reading that correctly, maybe im not ha!

    For Derek or any The Bat users…

    I’m fairly new to the research aspect of DFS (I was a plug and play guy). Does The Bat require understanding of saber-metrics and how to fit the pieces together or is it ‘beginner’ friendly, helping to use the projections to build your own lineup as well as the optimized lineup from the program?

    I’m told that the development team is working on a time stamp, and I’ve asked if we can include some weather columns. As far as the list of teams in projections, you should be able to get that pretty easily by looking at the pitchers page.

    1) A feature that will let you select the slate is in the process of being added

    2) These are the projected BA/OBP/SLG/wOBA for that player that day given the matchup he’s in

    3) Unfortunately, while we list the matchup factors, there are no plans to distribute what the quality of each factor is

    Yeah, they dropped a little bit right before lock when the umpire got announced, but mostly that’s just variance. It was a good matchup.

    You’re correct on this. I’m going to have the tech team fix this.

    THE BAT is streamlined in such a way that a beginner shouldn’t have much issue using it to build lineups, but it can also be incorporated as part of a larger research process for more advanced players as well. Like Majorrock said, if you check out the tutorial, that should give you an idea as to the simplicity of it.

  • maksik

    Derek, do you distribute backtest of your projection model? By how much do you outperform simple woba+vegas? I am interested in the confidence levels for all predicted quantities and predicted versus realized for last two years.
