    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 haven’t conducted any studies on the accuracy of the system

    This seems to be at odds with what simsina quoted, i.e. “the sound methodology, process, and analytical rigor behind THE BAT (and its track record) stand on their own”. Have you performed some type of cross-validation or was your test set the same as your training set?

    To chime in on the question related to variability of lineups for multiple lineups, the RG lineup builder that is configured to load BAT projections has a sliding scale for you to set the level of variability that you desire for multiple lineups. It’s under the settings.

    I’ve performed lots of tests to maximize the accuracy of various components of the system (i.e. how many years of data to use and in what proportion, etc.), but I haven’t compared the accuracy of the final projections to anything. I’d need something to compare it to (Vegas, other systems, etc.) for something like that to hold any meaning, and I didn’t have the technical skills or time to pull that kind of information together last year with everything going on. It is something I’m planning on doing this year, though, as I expect the processes of the system itself to cause it to perform well in this regard.

    So you’ve performed lots of tests to maximize the accuracy of various components of the system but have never checked to see how accurate your projections are.

    To be clear, in a previous post by a mod, a link was provided in which you said “the sound methodology, process, and analytical rigor behind THE BAT (and its track record) stand on their own”. That link is no longer accessibile (I’m still waiting for the mod who said he will check up on it to reply). To which you later said that “track record” was the wrong word choice because you actually have no data, and that reputation would be more apt. Am i misrepresenting anything ?

    Correct. And I don’t believe there was a ever a link there. Not sure what it would link to.

    Quoting Derek from this post since it covers some of the recent questions here.

    “What needs to be understood for anyone playing DFS MLB with the goal of winning (and which I’m sure most RG readers understand) is that even though it’s called “daily fantasy,” it truly needs to be approached from a long-term perspective. Anything can happen in a short amount of time — Mike Trout has weeks where he hits .125 — but in the long-run things even out. While anything can happen in a one-week test drive, win or lose it shouldn’t make any difference to someone who is looking to use THE BAT effectively. While there are no guarantees when it comes to predicting the future, the sound methodology, process, and analytical rigor behind THE BAT (and its track record) stand on their own. And it’s important for anyone hoping to use a system like THE BAT effectively (or anyone hoping to profit from DFS in general) to realize that a sound process is vastly more important than any results of a trial sample.”

    Sorry, Dee, I was updating the way projected lineups are handled this afternoon. Temporary glitch, should be fixed now.

    Depends on how you define success. I played 3 of the 4 days days using only The Bat projections and my own assessments of which stacks to target which came close to most of the bats suggestions which validated my thinking. The players I did not like I swapped out to others. I played only GPPs and cashed (profited both times) 2 out of the 3 days. The day I didnt was opening day. The sample size is much to small an my winnings were not top 10% but I felt comfortable using The Bat. When I have the time to pair it with more research and as the season progress I will continue to evaluate how I feel. I am sticking with The Bat throughout the season and compare it to how I did last year when I was alone and afraid with no premium subscription service and ended very well into the green,

    Thanks I found that and it was set at 10. If I move it to 5 will that make more variety of lineups? Not sure i completely understand how that works,

    thanks,

    The Bat debuted on a different site two years ago and I decided to give it a shot. I was very successful with The Bat in its debut year. Based on my success with it I reupped last year and had zero success. As a result I have not bought it this year. One thing I will say is that I found The Bat more accurate with pitchers than hitter, especially the first year it was out.

    With The Bat, I have had success, but the user still needs to make decisions. There might be several guys within a half point projection from each other. No system is perfect but I appreciate it being on here, and happy to be a subscriber, regardless of how I use it.

  • flip4flop

    Took down the Aces $11 GPP last night with help from TheBat so I would say its paid for itself at this point. It still requires user thought as has been mentioned there are many players that are close in projection. Based on other factors adn research you have to make your own call.

    Love the updates but we can please get an option to sort by slate!

    BAT is definitely one of the best systems out there you can pay for a $150 is a more than fair price. As said here, any projection system is only as successful as how you use it, but Carty knows his stuff and his product is a great resource.

    I would echo this desire for slate-specific sorting. Once that feature is added, it will be exactly what I need.

    Congrats flip4flop on the success last night on Aces!

    Last night was the first night I can say that I truly utilized THE BAT due to rainouts, split slates, etc. I cashed my Double-Ups on both slates thanks mainly to Ryan Braun who THE BAT projected as top-10. I did not really have Braun on my radar, so I was stoked with that recommendation.

    As others have said, there’s still a great deal of variability in terms of user decision. I am considering a blog utilizing THE BAT projections, but I have not yet fully decided how best to structure it. I know tvsfrink has an awesome forum thread going where he compares RG optimal lineup, THE BAT optimal lineup, and his own modified BAT lineup daily.

    @MickyD10970 I am not sure the answer. I have not really used it; I only know it’s there as an option.
