What is the Nasty Factor?
The Nasty Factor evaluates several properties of each pitch, and rates the "nastiness" of the pitch on a scale from 0-100, based in part on the success or failure of opposing hitters against previous similar pitches. The Nasty Factor incorporates several different factors for each pitch, including:
- Velocity — The greater the pitch's velocity — as compared to that pitcher's and the league's range of speed for that pitch type — the greater the nastiness;
- Sequence — The more the pitcher mixes up his pitches, the greater the nastiness… and certain pitch sequences are nastier than others, too;
- Location — The closer to the edges of the strike zone is, the greater the nastiness, while pitches closer to the middle of the plate, and farther away outside the strike zone, decrease in nastiness;
- Movement — The more movement the pitcher applies to the pitch — as compared to that pitcher's and the league's range of movement for that pitch type — the greater the nastiness.
The Nasty Factor also adjusts for how often the pitcher has faced the current batter during the game, as well as how often he has used the same pitch type against the same batter in the current at-bat and previously in the game.
Hot / Cold Zones
Use the hot/cold zones to find the pitch locations in which the current batter and pitcher perform their best, and where they struggle. The strike zone is divided into nine regions and balls are grouped into four regions, with each zone color-coded to indicate whether the batter or pitcher is hot or cold in that zone.
- Red and pink zones show where the batter outperforms his season OPS (or where the pitcher betters his season OPS allowed)
- Light and dark blue zones show where the batter underperforms his season OPS (or where the pitcher is worse than his season OPS allowed).
- White zones show where the batter's performance is comparable with his season OPS (or where the pitcher's performance is comparable to his season OPS allowed).
In addition, the hot/cold zone displays can be filtered by splits according to pitch types faced or thrown, ball/strike count, number of outs, baserunners, and vs. left/right. Choosing a particular split not only updates the statistics, it also gives you a detailed look at the hot/cold zones for that particular situation.
For example, you can see that a particular hitter loves to hit changeups low and inside, but struggles against the fastball in the same zone - or you can see if a pitcher tends to work down in the zone with runners in scoring position.
Pitcher / Batter Tendencies
Use pitcher tendencies to get an overview of the pitcher's performance throughout the game and compared to his previous outtings. Using Pitch-f/x data, we determine the properties of every pitch and track the changes in these values over time:
- Pitch Type
- Release Point
This enables you to tell if a pitcher is losing bite on his slider, throwing harder to get through one more inning, relying more on off-speed pitches as the game goes on, or dropping his arm angle as he fatigues.
Velocity and movement are calculated on a per-pitch basis for each inning in the current game as well as season-to-date and last five games, so you can see how this outing stacks up against the pitcher's historical performance. Release points are also broken down by pitch type, enabling you to notice if the pitcher is changing his arm angle or perhaps 'tipping' different pitches.

Pitch F/X versus Break
The revolutionary Pitch-F/x technology, exclusive to MLB.com Gameday, describes the movement of each pitch with two values: Pitch-F/x versus Break.
- The Pitch-f/x or 'PFX' value is the distance between the location of the actual pitch, and the calculated location of a ball thrown by the pitcher in the same way but with no spin; this is the amount of 'movement' the pitcher applies to the pitch.
- Break is the greatest distance between the trajectory of the pitch at any point between the release point and the front of home plate, and the straight line path from the release point and the front of home plate.
- A faster, straighter pitch like a fastball will have a higher Pitch-F/x value than a slower, breaking ball like a curveball, which will have a higher break.
Enhanced Pitch Type Identification
Our real-time pitch type identification utilizes software known as an artificial neural network, which compares a series of training pitches, generously provided by Mike Fast and Major League baseball clubs, to each pitch as it is thrown. The results are then tailored to each pitcher's specific pitch repertoire and normal velocities for the most likely match. Each pitch-type is grouped and color-coded in Gameday:
Full 3D Pitch-by-Pitch Visualization
Use the controls in the 3D interface to zoom in or out, rotate around the action, or tilt up and down.
- Select one of three pre-defined camera positions (behind the pitcher, behind the batter or "high home"), or take over the controls at any time for a better look at the pitches from any point in the game.
- The batter model and strike zone are scaled to the exact height of the player currently at bat.
- Use the Options button to toggle to "light" mode for a more optimized experience on slower computers.
