Spray Charts by Neil Weinberg March 30, 2016 Spray charts are useful for recording individual events and illuminating player tendencies. If you want to know about a specific play, you might look to a spray chart to tell you where the ball went, but spray charts are most often used to determine if player pulls the ball often or if his fly balls tend to go to right field or left field. FanGraphs has spray charts for batters, fielders, and pitchers, available by clicking on the tab at the top of the stat portion of their player page, based on Inside Edge data. For hitters, you’ll start with something like this: You can toggle between batted balls (the player as a hitter) and fielding location (the player as a fielder), which we’ll do in a moment, but first we’ll walk through the options. You have the option of selecting a player and then your chart types, seasons, and the handedness of the pitcher. In chart type, you can select to display the data by hang time, batted ball type, or hit type. In the season drop down, you can select any year from 2012 forward, or any consecutive stretch of years in that window. Handedness allows you to choose all pitchers, righties, or lefties. You’ll also notice that the site displays two charts side by side so that you can select different options and compare. Remember to hit Refresh All Charts when you want to update the page to reflect your change. As with many features on the site, the icon in the upper right corner of the chart allows you to download and embed the results as you wish. The basic functions of the fielding side of things are the same: This time the chart type options are made plays, missed plays, or made/missed plays. The season function works the same and you can select the player’s position as well if you have a player who gets reps at multiple spots. The percentages refer to the Inside Edge fielding data we have on the site which puts plays into buckets based on the probability a play gets made. Pitchers have the same fielding charts as hitters, but their default charts reflect batted balls with them on the mound. The options are the same as if you’re looking at a hitter’s charts from a functionality perspective: You might notice that for players with lots of plate appearances, batters faced, or fielding chances that the charts can get cluttered quickly. To help alleviate that problem, you have the ability to click the key at the bottom of the page (i.e., the green dot that has ground ball next to it) to turn the display on and off. Here is the exact same example, with ground balls turned off. Here’s what it looks like to embed a spray chart: Source: FanGraphs If you have any questions about functionality, don’t hesitate to ask. And if you’re feeling extra ambitious, check out Bill Petti’s spray chart tool which takes similar data from PITCHf/x and offers many additional features.
