Errors in Baseball Pitch

Describing baseball pitch movement with right-hand rules

The right-hand rules show the direction of the spin-induced deflection of baseball pitches: thus, they explain the movement of the fastball, curveball, slider and screwball. The direction of deflection is described by a pair of right-hand rules commonly used in science and engineering. Our new model for the magnitude of the lateral spin-induced deflection of the ball considers the orientation o...

Using Multi-Class Classification Methods to Predict Baseball Pitch Types

Since the introduction of PITCHf/x in 2006, there has been a plethora of data available for anyone who wants to access to the minute details of every baseball pitch thrown over the past nine seasons. Everything from the initial velocity and release point to the break angle and strike zone placement is tracked, recorded, and used to classify the pitch according to an algorithm developed by MLB A...

Effect of pitch type, pitch count, and pitching mechanics on risk of elbow and shoulder pain in youth baseball pitchers.

BACKGROUND Joint pain is thought to be an early sign of injury to a pitcher. OBJECTIVE To evaluate the association between pitch counts, pitch types, and pitching mechanics and shoulder and elbow pain in young pitchers. STUDY DESIGN Prospective cohort study. METHODS Four hundred and seventy-six young (ages 9 to 14 years) baseball pitchers were followed for one season. Data were collected ...

Effect of First Pitch type and Outcome on Hitter Success in High School Baseball

The effect of pitch type on ground reaction forces in the baseball swing.

Coaches have identified the batter's weight shift as a critical component for promoting proper timing and balance in a baseball swing. Analysing the weight shift through maximum horizontal (Fx) and vertical (Fz) ground reaction forces (GRFs) of professional batters (N = 29; height = 185 +/- 6 cm; mass = 92 +/- 9 kg), the purpose of this study was to compare GRFs among swings against fastballs a...
