NEW MLB DFS TOOL: Introducing PlateIQ

By Brian Hourigan (CruzinToVictory), Last Updated 1 month ago

DFS baseball is unique from every other daily fantasy sport in that it’s all about individual matchups. A pitcher goes head to head against each hitter one by one, making each individual matchup just as important as the next.

Several months ago, the team here at RotoGrinders set out to create a tool that could bring together all of the relevant data about each of these matchups into one place, while also creating some new insight that you couldn’t find anywhere else. Hence, PlateIQ was born.

What is PlateIQ?

PlateIQ is a FREE, all-in-one dashboard that provides all of the relevant data about a particular matchup. You simply select a game from today’s slate, and it will automatically select the starting pitcher for that game and display his stats against each hitter he is expected to face.

All of the basics that you expect can be found in the main hitter table at the top of the page:

Here you will find everything from ISO to wOBA to batted ball rates; Essentially every stat that we find important in a hitter’s matchup. If you see a clock icon next to their batting order, it means they are in our projected starting lineup, and if they have a green check, it means they have been confirmed.

In addition to each individual’s stats, we also have aggregate data at the bottom of the table, and this is where this section really shines. Sure, you can find “Boston K rate against righties” in a lot of places, but this is the only place where you’ll find today’s starting lineup’s K rate against righties! We average every hitter’s data, excluding players with very small sample sizes, to avoid outliers skewing the data. This is a great way to get a quick glance at the overall matchup and what you can expect from the team against today’s starting pitcher.

Pitcher Data and Heat Maps

In addition to individual hitter data, you will find relevant statistics for the pitcher in the table at the top right of the page. Simple data for lefty/righty splits gives you a quick glance of how effective today’s starter is against each handedness. We will constantly be adding more to this table, but these are a great place to get started. Heck, you can even choose a different pitcher from the drop down if you wanted to research for a future slate!

The Heat Maps chart is where things really start to get fun.

We’ve broken the location of each pitch down into different zones; The main nine zones are strikes, and the four grey outside zones are balls. Using these zones, we’ve mapped out two things:

— How often the pitcher throws a pitch in each zone, and
— How often a hitter gets a hit in each of those zones.

In the above example, we see that Tanaka throws pretty often to the right side of the zone against lefties, while Mitch Moreland gets 27.5% of his hits from pitches in the bottom right and middle right zone. While this obviously doesn’t guarantee success, it’s yet another indicator that you can add to your research if you’re unsure on a particular hitter.

At the moment, you can compare the heat maps for any individual hitter, but in a future update, you’ll also be able to look at the aggregate data for all righties, lefties, or the entire lineup against today’s starting pitcher.

Pitch Type Breakdown

This is where things get a little crazy and, in my opinion, very cool. We wanted to come up with a way to take the data we have on individual pitch types to determine A) How successful a hitter is vs certain types of pitches, and B) How often the pitcher he’s facing actually throws that type of pitch. This tool went through a number of iterations, and will continue to evolve over time, but there is still plenty you can garner from its current form.

OK so this one looks a little intimidating, but let me explain.

The charts on the left hand side are called “spider charts”, and they’re used to display this type of frequency data for multiple data points all at once. Let’s start with the pitcher side:

In the above example, you can see two lines on the pitcher spider chart. Each “spoke” of the chart represents a pitch type (CH = changeup, SP = splitter, CT = Cutter, etc) and the grey line is the normalized league average frequency of that pitch type. We decided to normalize the league average because some pitches are thrown so frequently (or infrequently, in the case of something like a knuckle ball), that it made the chart difficult to read.

The blue line in the chart represents, in this case, the frequency at which Tanaka throws certain pitch types. So in this example, Tanaka throws many more splitters than the league average, as well as an above average amount of sliders, sinkers, and cutters.

With this in mind, we can now look at the hitter chart to see if we can find anything to indicate success against those pitches. The goal for good hitting matchup is to have the hitter’s chart show spikes on the same pitch types that the pitcher is showing. This would indicate that the hitter records a large number of hits against that pitch type, which is obviously a good thing if he’s going to see a bunch of those pitches today.

So in this example, Moreland gets a higher than league average amount of hits from curve balls, cutters, change ups, and splitters, but struggles against sliders, and has some difficulty with sinkers.This leads to an interesting situation, because we already saw that Tanaka throws a ton of splitters (which Moreland is successful against), but also a fair amount of sliders and sinkers (which Moreland struggles with). At the end of the day you’ll have to decide how you believe that effects the matchup, but it’s one more data point to help you make that final decision about rostering a player.

Summary

PlateIQ was designed to present all of the most important data about an individual matchup in one, easy to use place. Our goal was to aggregate things you would normally need to search multiple places for, while also adding some new features that focus on daily fantasy implications that you can’t find anywhere else. I’m extremely excited about what we came up with, and I hope you are too! So dig in, play around with the data, and go win some GPPs!

After you’ve had some time to play around with it, let us know what you think! Are there certain stats that you’d like to see added? Features that you’re interested in? Let us know in the comments below, because this tool will also be constantly evolving over time, and we’d love to hear what you want us to add first.

    Hi,

    Do you happen to be using an older version of Internet Explorer? If so, can you give it a try on Chrome or see if you have a browser update available in your settings?

    What browser, browser version, and operating system are you using? We’re noticing some issues with the stats loading for people on older browsers and are looking into it.

  • Whereschris

    Using Safari version 6.1.6 on my Mac. For what its worth, it is working on my iPhone. Thanks for looking in to it!

  • cantclark

    Great stuff

  • SweeneyPhoto

    Works awesome, thanks for this, my new favorite tool!

  • SweeneyPhoto

    PS, you might want to note if the heat maps are “catchers view” or “pitchers view”.

  • tonytone1908

    I’m on Chrome on my PC and it’s not showing any data. No numbers for anyone.

  • Rainmakers5

    No stats load here. Tried in Safari on IPad, IE on PC, Chrome on PC, and Chrome and Samsung Internet on Android

  • Whereschris

    It was working on my phone but not anymore

  • Brandon684

    Just the tool I needed! Thanks!

    We had a moment of unavailability while something updated. Should be back up now

  • nateshidler

    Cant believe this is going to be a free tool. Amazing amount of data. You are going to put JT and Cheezels out of a job

  • Shacko13

    Just an FYI… It’s working for me on Google Chrome but on Internet Explorer no stats are loading, everything is at 0%. I’m using the most up to date version of IE 11 for Windows 7. —— It does look like this will be a valuable free tool. Will there be any “extras” or more in-depth stats/info available using the tool for Premium members?

    No, the data from this tool is from our own data provider, Sportradar.

    That’s a good point, Sweeney. Thanks for the feedback!

    IT SHOULD SHOW HARD CONTACT

    And Mitch Moreland hits a homer tonight

    Albeit on the wrong pitch, in the wrong place lol.

    Seriously, though, this tool is sick. Thank you, Rotogrinders!

  • Vicar

    The Plate IQ rocks. I played Avisail Garcia and Alex Avila to fill last 2 spots. Dongs for both!

  • Vicar

    As for hard contact why do you need a tool for that? You should know who hits the ball hard and use the spider web to tell you if player X hits that pitch well in the zones that pitcher X throws it in at a high %.

    IMO great tool to leverage against elite pitchers for GPP’s 1 or 2 offs to be contrarian.
