Pitch Movement

Created with Highcharts 6.2.0Chart context menuJack Flaherty Vertical Movement vs Avg (Inches) by SeasonSource: baseballsavant.mlb.comFour SeamerCurveballSliderChangeupSinkerCutter201720182019202020212022202320242025-7.5-5-2.502.557.5

How this works: This section shows two different ways to evaluate pitch movement. On the left, “Total Movement” shows the real-world movement of a pitch, including the forces of gravity, which affects every pitch thrown. Since gravity requires time, and slower pitches aren't 'better' just because they have more time to move, a pitch's movement is compared to other pitches of the same pitch type, within +/- 2 MPH and +/- 0.5 feet of extension/release. On the right, Induced Movement (or IVB) is reported without gravity, and attempts to isolate movement created by the pitcher's ability to spin and manipulate the ball.
