Introducing cricpy:A python package to analyze performances of cricketers

Full many a gem of purest ray serene,
The dark unfathomed caves of ocean bear;
Full many a flower is born to blush unseen,
And waste its sweetness on the desert air.

            Thomas Gray, An Elegy Written In A Country Churchyard


It is finally here! cricpy, the python avatar , of my R package cricketr is now ready to rock-n-roll! My R package cricketr had its genesis about 3 and some years ago and went through a couple of enhancements. During this time I have always thought about creating an equivalent python package like cricketr. Now I have finally done it.

So here it is. My python package ‘cricpy!!!’

This package uses the statistics info available in ESPN Cricinfo Statsguru. The current version of this package supports only Test cricket

You should be able to install the package using pip install cricpy and use the many functions available in the package. Please mindful of the ESPN Cricinfo Terms of Use

Note 1: Cricpy can now analyze performances of teams in Test, ODI and T20 cricket see Cricpy adds team analytics to its arsenal!!

Note 2: Cricpy can also do granular analysis of players click Cricpy performs granular analysis of players

This post is also hosted on Rpubs at Introducing cricpy. You can also download the pdf version of this post at cricpy.pdf

Do check out my post on R package cricketr at Re-introducing cricketr! : An R package to analyze performances of cricketers

If you are passionate about cricket, and love analyzing cricket performances, then check out my racy book on cricket ‘Cricket analytics with cricketr and cricpy – Analytics harmony with R & Python’! This book discusses and shows how to use my R package ‘cricketr’ and my Python package ‘cricpy’ to analyze batsmen and bowlers in all formats of the game (Test, ODI and T20). The paperback is available on Amazon at $21.99 and  the kindle version at $9.99/Rs 449/-. A must read for any cricket lover! Check it out!!


This package uses the statistics info available in ESPN Cricinfo Statsguru.

Note: If you would like to do a similar analysis for a different set of batsman and bowlers, you can clone/download my skeleton cricpy-template from Github (which is the R Markdown file I have used for the analysis below). You will only need to make appropriate changes for the players you are interested in. The functions can be executed in RStudio or in a IPython notebook.

The cricpy package

The cricpy package has several functions that perform several different analyses on both batsman and bowlers. The package has functions that plot percentage frequency runs or wickets, runs likelihood for a batsman, relative run/strike rates of batsman and relative performance/economy rate for bowlers are available.

Other interesting functions include batting performance moving average, forecasting, performance of a player against different oppositions, contribution to wins and losses etc.

The data for a particular player can be obtained with the getPlayerData() function. To do this you will need to go to ESPN CricInfo Player and type in the name of the player for e.g Rahul Dravid, Virat Kohli, Alastair Cook etc. This will bring up a page which have the profile number for the player e.g. for Rahul Dravid this would be Hence, Dravid’s profile is 28114. This can be used to get the data for Rahul Dravid as shown below

The cricpy package is almost a clone of my R package cricketr. The signature of all the python functions are identical with that of its R avatar namely  ‘cricketr’, with only the necessary variations between Python and R. It may be useful to look at my post R vs Python: Different similarities and similar differences. In fact if you are familiar with one of the languages you can look up the package in the other and you will notice the parallel constructs.

You can fork/clone the cricpy package at Github cricpy

The following 2 examples show the similarity between cricketr and cricpy packages

1a.Importing cricketr – R

Importing cricketr in R


2a. Importing cricpy – Python

# Install the package
# Do a pip install cricpy
# Import cricpy
import cricpy
# You could either do
import as ca 
#ca.batsman4s("../dravid.csv","Rahul Dravid")
# Or
from import *
#batsman4s("../dravid.csv","Rahul Dravid")

I would recommend using option 1 namely ca.batsman4s() as I may add an advanced analytics module in the future to cricpy.

2 Invoking functions

You can seen how the 2 calls are identical for both the R package cricketr and the Python package cricpy

2a. Invoking functions with R package ‘cricketr’

batsman4s("../dravid.csv","Rahul Dravid")

2b. Invoking functions with Python package ‘cricpy’

import as ca 
ca.batsman4s("../dravid.csv","Rahul Dravid")

3a. Getting help from cricketr – R


3b. Getting help from cricpy – Python

## Help on function getPlayerData in module

The details below will introduce the different functions that are available in cricpy.

3. Get the player data for a player using the function getPlayerData()

Important Note This needs to be done only once for a player. This function stores the player’s data in the specified CSV file (for e.g. dravid.csv as above) which can then be reused for all other functions). Once we have the data for the players many analyses can be done. This post will use the stored CSV file obtained with a prior getPlayerData for all subsequent analyses

import as ca
#dravid =ca.getPlayerData(28114,dir="..",file="dravid.csv",type="batting",homeOrAway=[1,2], result=[1,2,4])
#acook =ca.getPlayerData(11728,dir="..",file="acook.csv",type="batting",homeOrAway=[1,2], result=[1,2,4])
import as ca
#lara =ca.getPlayerData(52337,dir="..",file="lara.csv",type="batting",homeOrAway=[1,2], result=[1,2,4])253802
#kohli =ca.getPlayerData(253802,dir="..",file="kohli.csv",type="batting",homeOrAway=[1,2], result=[1,2,4])

4 Rahul Dravid’s performance – Basic Analyses

The 3 plots below provide the following for Rahul Dravid

  1. Frequency percentage of runs in each run range over the whole career
  2. Mean Strike Rate for runs scored in the given range
  3. A histogram of runs frequency percentages in runs ranges
import as ca
import matplotlib.pyplot as plt
ca.batsmanRunsFreqPerf("../dravid.csv","Rahul Dravid")

ca.batsmanMeanStrikeRate("../dravid.csv","Rahul Dravid")

ca.batsmanRunsRanges("../dravid.csv","Rahul Dravid") 

5. More analyses

import as ca
ca.batsman4s("../dravid.csv","Rahul Dravid")

ca.batsman6s("../dravid.csv","Rahul Dravid") 

ca.batsmanDismissals("../dravid.csv","Rahul Dravid")

6. 3D scatter plot and prediction plane

The plots below show the 3D scatter plot of Dravid Runs versus Balls Faced and Minutes at crease. A linear regression plane is then fitted between Runs and Balls Faced + Minutes at crease

import as ca
ca.battingPerf3d("../dravid.csv","Rahul Dravid")

7. Average runs at different venues

The plot below gives the average runs scored by Dravid at different grounds. The plot also the number of innings at each ground as a label at x-axis. It can be seen Dravid did great in Rawalpindi, Leeds, Georgetown overseas and , Mohali and Bangalore at home

import as ca
ca.batsmanAvgRunsGround("../dravid.csv","Rahul Dravid")

8. Average runs against different opposing teams

This plot computes the average runs scored by Dravid against different countries. Dravid has an average of 50+ in England, New Zealand, West Indies and Zimbabwe.

import as ca
ca.batsmanAvgRunsOpposition("../dravid.csv","Rahul Dravid")

9 . Highest Runs Likelihood

The plot below shows the Runs Likelihood for a batsman. For this the performance of Sachin is plotted as a 3D scatter plot with Runs versus Balls Faced + Minutes at crease. K-Means. The centroids of 3 clusters are computed and plotted. In this plot Dravid’s  highest tendencies are computed and plotted using K-Means

import as ca
ca.batsmanRunsLikelihood("../dravid.csv","Rahul Dravid")

10. A look at the Top 4 batsman – Rahul Dravid, Alastair Cook, Brian Lara and Virat Kohli

The following batsmen have been very prolific in test cricket and will be used for teh analyses

  1. Rahul Dravid :Average:52.31,100’s – 36, 50’s – 63
  2. Alastair Cook : Average: 45.35, 100’s – 33, 50’s – 57
  3. Brian Lara : Average: 52.88, 100’s – 34 , 50’s – 48
  4. Virat Kohli: Average: 54.57 ,100’s – 24 , 50’s – 19

The following plots take a closer at their performances. The box plots show the median the 1st and 3rd quartile of the runs

11. Box Histogram Plot

This plot shows a combined boxplot of the Runs ranges and a histogram of the Runs Frequency

import as ca
ca.batsmanPerfBoxHist("../dravid.csv","Rahul Dravid")

ca.batsmanPerfBoxHist("../acook.csv","Alastair Cook")

ca.batsmanPerfBoxHist("../lara.csv","Brian Lara")

ca.batsmanPerfBoxHist("../kohli.csv","Virat Kohli")

12. Contribution to won and lost matches

The plot below shows the contribution of Dravid, Cook, Lara and Kohli in matches won and lost. It can be seen that in matches where India has won Dravid and Kohli have scored more and must have been instrumental in the win

For the 2 functions below you will have to use the getPlayerDataSp() function as shown below. I have commented this as I already have these files

import as ca
#dravidsp = ca.getPlayerDataSp(28114,tdir=".",tfile="dravidsp.csv",ttype="batting")
#acooksp = ca.getPlayerDataSp(11728,tdir=".",tfile="acooksp.csv",ttype="batting")
#larasp = ca.getPlayerDataSp(52337,tdir=".",tfile="larasp.csv",ttype="batting")
#kohlisp = ca.getPlayerDataSp(253802,tdir=".",tfile="kohlisp.csv",ttype="batting")
import as ca
ca.batsmanContributionWonLost("../dravidsp.csv","Rahul Dravid")

ca.batsmanContributionWonLost("../acooksp.csv","Alastair Cook")

ca.batsmanContributionWonLost("../larasp.csv","Brian Lara")

ca.batsmanContributionWonLost("../kohlisp.csv","Virat Kohli")

13. Performance at home and overseas

From the plot below it can be seen

Dravid has a higher median overseas than at home.Cook, Lara and Kohli have a lower median of runs overseas than at home.

This function also requires the use of getPlayerDataSp() as shown above

import as ca
ca.batsmanPerfHomeAway("../dravidsp.csv","Rahul Dravid")

ca.batsmanPerfHomeAway("../acooksp.csv","Alastair Cook")

ca.batsmanPerfHomeAway("../larasp.csv","Brian Lara")

ca.batsmanPerfHomeAway("../kohlisp.csv","Virat Kohli")

14 Moving Average of runs in career

Take a look at the Moving Average across the career of the Top 4 (ignore the dip at the end of all plots. Need to check why this is so!). Lara’s performance seems to have been quite good before his retirement(wonder why retired so early!). Kohli’s performance has been steadily improving over the years

import as ca
ca.batsmanMovingAverage("../dravid.csv","Rahul Dravid")

ca.batsmanMovingAverage("../acook.csv","Alastair Cook")

ca.batsmanMovingAverage("../lara.csv","Brian Lara")

ca.batsmanMovingAverage("../kohli.csv","Virat Kohli")

15 Cumulative Average runs of batsman in career

This function provides the cumulative average runs of the batsman over the career. Dravid averages around 48, Cook around 44, Lara around 50 and Kohli shows a steady improvement in his cumulative average. Kohli seems to be getting better with time.

import as ca
ca.batsmanCumulativeAverageRuns("../dravid.csv","Rahul Dravid")

ca.batsmanCumulativeAverageRuns("../acook.csv","Alastair Cook")

ca.batsmanCumulativeAverageRuns("../lara.csv","Brian Lara")

ca.batsmanCumulativeAverageRuns("../kohli.csv","Virat Kohli")

16 Cumulative Average strike rate of batsman in career

Lara has a terrific strike rate of 52+. Cook has a better strike rate over Dravid. Kohli’s strike rate has improved over the years.

import as ca
ca.batsmanCumulativeStrikeRate("../dravid.csv","Rahul Dravid")

ca.batsmanCumulativeStrikeRate("../acook.csv","Alastair Cook")

ca.batsmanCumulativeStrikeRate("../lara.csv","Brian Lara")

ca.batsmanCumulativeStrikeRate("../kohli.csv","Virat Kohli")

17 Future Runs forecast

Here are plots that forecast how the batsman will perform in future. Currently ARIMA has been used for the forecast. (To do:  Perform Holt-Winters forecast!)

The fitted model is then used to predict the runs that the batsmen will score for a given Balls faced and Minutes at crease.

22 Analysis of Top 3 wicket takers

The following 3 bowlers have had an excellent career and will be used for the analysis

  1. Glenn McGrath:Wickets: 563, Average = 21.64, Economy Rate – 2.49
  2. Kapil Dev : Wickets: 434, Average = 29.64, Economy Rate – 2.78
  3. James Anderson: Wickets: 564, Average = 28.64, Economy Rate – 2.88

How do Glenn McGrath, Kapil Dev and James Anderson compare with one another with respect to wickets taken and the Economy Rate. The next set of plots compute and plot precisely these analyses.

23. Get the bowler’s data

This plot below computes the percentage frequency of number of wickets taken for e.g 1 wicket x%, 2 wickets y% etc and plots them as a continuous line

import as ca

Key Findings

The plots above capture some of the capabilities and features of my cricpy package. Feel free to install the package and try it out. Please do keep in mind ESPN Cricinfo’s Terms of Use.

Here are the main findings from the analysis above

Key insights

1. Brian Lara is head and shoulders above the rest in the overall strike rate
2. Kohli performance has been steadily improving over the years and with the way he is going he will shatter all records.
3. Kohli and Dravid have scored more in matches where India has won than the other two.
4. Dravid has performed very well overseas
5. The cumulative average runs has Kohli just edging out the other 3. Kohli is probably midway in his career but considering that his moving average is improving strongly, we can expect great things of him with the way he is going.
6. McGrath has had some great performances overseas
7. Mcgrath has the best economy rate and has contributed significantly to Australia’s wins.
8.In the cumulative average wickets race McGrath leads the pack. Kapil leads Anderson till about 150 matches after which Anderson takes over.
