This repository hosts two Streamlit applications designed to analyze MLB pitchers' pitch movement and consistency using 2024 Statcast data.
-
Shape Consistency App:
- Analyze a pitcher’s ability to consistently repeat the shape of their pitches.
- Search for a pitcher, select a pitch type, and visualize its movement profile along with a consistency score.
-
Movement Profile Distributions App:
- View violin plots of horizontal and vertical movement, as well as velocity distributions, for each pitch type in a pitcher's arsenal.
- Rank pitches by their shape consistency and compare them to other pitchers throwing the same pitch type.
Both apps utilize the 2024 Statcast monthly data files.
-
Search for MLB Pitchers:
- Find and select a pitcher from the dataset.
-
Pitch Arsenal Dropdown:
- Choose from the available pitch types in the pitcher's arsenal.
-
Pitch Movement Visualization:
- Display a movement plot of the selected pitch type (horizontal and vertical break).
-
Consistency Score:
- View a calculated consistency score for each pitch type based on its movement repeatability.
-
Search and Filter:
- Search or select a pitcher from the dataset.
-
Violin Plots:
- View horizontal break, vertical break, and velocity distributions for all pitch types in the pitcher's arsenal.
- Each pitch type is color-coded for clarity, with a key displayed next to the graphs.
-
Shape Consistency Ranking:
- Rank pitches in a pitcher's arsenal based on their movement and velocity consistency (lowest standard deviation first).
- Includes percentile rankings for each pitch type compared to other pitchers in the dataset.
-
Definitions:
- Clear definitions for consistency score, density, and percentile are provided to aid interpretation.
- Python 3.8 or later
