Cricket is a sport of statistics. So how do we use all these stats to find some insights? This post will demonstrate how you can develop a very basic win probability model using Python and cricket match data—here's an example of how we do data science in sport.
Why Win Probability Matters
Of note are Win Probability Models. These can assist broadcasters to make sense of the game when momentum shifts, evolving in real-time as wickets fall and runs accumulate, overs pass, and the run-rate tightens. They're a thousand times more sophisticated than betting odds, but designing such a thing is a good way for techie types working with data to understand time-series logistic regression.
Dataset Preparation
In this example, we have used real ball-by-ball datasets which are available on the internet (e.g., Cricsheet). Key features include:
Current Score & Wickets
Overs Remaining
Run Rate Required
Historical Win % for Similar Situations
Note: Make sure whatever sets of data you are planning to use are licensed. Use any public data for the sole purpose of education/learning and not in a betting/gambling business.
Python Implementation: Logistic Regression Baseline
Below is a sample implementation in scikit-learn. Keep in mind this is just a baseline; actual production models have many more features and rigorous validation.
import pandas as pd
from sklearn.linear_model import LogisticRegression
from sklearn.model_selection import train_test_split
Load preprocessed ball-by-ball data
df = pd.read_csv('cricket_matches.csv')
Feature selection
features = ['runs', 'wickets', 'overs_remaining', 'required_run_rate']
X = df[features]
y = df['match_winner'] # Binary: 1 = Batting Team Wins, 0 = Bowling Team Wins
Train/Test Split
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)
Model Training
model = LogisticRegression()
model.fit(X_train, y_train)
Prediction Example
new_situation = [[150, 3, 10.2, 8.5]] # 150 runs, 3 wickets, 10.2 overs left, RRR 8.5
probability = model.predict_proba(new_situation)[0][1]
print(f"Win Probability: {probability:.2%}")
Limitations & Ethical Considerations
This is not a perfect model at all and it overlooks a lot of other elements like pitch condition, type of players in the team, weather conditions, and team lineups. Sports data requires domain knowledge apart from knowledge of programming.
Having that in mind, the model is just there to help studying and analyzing. It should NEVER be used in any way to influence any decisions taken for financial, betting, or gambling purposes. There's NEVER a model that can predict the outcome of any sport, and betting always comes with a risk. Responsible data science knows its boundaries AND its limits.

Next Steps for Learners
Add player-specific features (strike rate, economy rate)
Experiment with ensemble methods (Random Forest, XGBoost)
Visualize probability swings using matplotlib/seaborn
Validate against actual match outcomes
