## Introduction

The *biggest nag* in the collective psyche of cricketing fraternity these days, is whether Virat Kohli has surpassed Sachin Tendulkar. This question has been troubling cricket lovers the world over and particularly in India, for quite a while. This nagging question has only grown stronger with Kohli’s 41st ODI century and with Michael Vaughan bestowing the *GOAT* title to Virat Kohli for ODI cricket. Hence, I decided to do my bit in addressing this, by doing analysis of Kohli’s and Tendulkar’s performance in ODI cricket. I also wanted to address the the best among the cricketing idols of India in Test cricket, namely Sunil Gavaskar, Sachin Tendulkar and Virat Kohli. Hence this post has 2 parts

- Analysis of Tendulkar, Gavaskar and Kohli in Test cricket
- Analysis of Tendulkar and Kohli in ODIs

In this post, I analyze the performances of these titans in Test and ODI cricket using my R package **cricketr**. While some may feel that comparisons are not possible as these batsmen are from different eras. To some extent this is true. I would give some leeway to Gavaskar as he had to bat in a pre-helmet era. But with Tendulkar and Kohli a fair and objective comparison is possible. There were pre-eminient bowlers in the times of Tendulkar as there are now.

From the analysis below, it can be seen that Tendulkar to of everybody else in Test cricket. However it must be noted that Tendulkar’s performance deteriorated towards the end of his career. Such was not the case with Gavaskar. Kohli has some catching up to do and he still has a lot of Test cricket in him.

In ODI Kohli can be seen to pulling ahead of Tendulkar in several aspects.

My R package **cricketr** can be installed directly from CRAN and you can use it analyze cricketers.

This package uses the statistics info available in ESPN Cricinfo Statsguru. The current version of this package supports all formats of the game including Test, ODI and Twenty20 versions.

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

### 1 Load the cricketr package

if (!require("cricketr")){ install.packages("cricketr",lib = "c:/test") } library(cricketr)

## A Test cricket – Analysis of Gavaskar, Tendulkar and Kohli

### 2. Get player data

tendulkar <- getPlayerData(35320,dir=".",file="tendulkar.csv",type="batting") kohli <- getPlayerData(253802,dir=".",file="kohli.csv",type="batting") gavaskar <- getPlayerData(28794,dir=".",file="gavaskar.csv",type="batting")

### 3a. Basic analyses for Tendulkar

par(mfrow=c(1,3)) par(mar=c(4,4,2,2)) batsmanRunsFreqPerf("./tendulkar.csv","Tendulkar") batsmanMeanStrikeRate("./tendulkar.csv","Tendulkar") batsmanRunsRanges("./tendulkar.csv","Tendulkar") dev.off()

### 3b Basic analyses for Kohli

### 4a.More analyses for Tendulkar

It can be seen that Tendulkar and Gavaskar has been bowled more often than Kohli. Also Kohli does not have as many sixes in Test cricket as Tendulkar and Gavaskar

par(mfrow=c(1,3)) par(mar=c(4,4,2,2)) batsman4s("./tendulkar.csv","Tendulkar") batsman6s("./tendulkar.csv","Tendulkar") batsmanDismissals("./tendulkar.csv","Tendulkar") dev.off()

### 6. Performance if batsmen against different Opposition

- Tendulkar averages 50 against the following countries – Australia, Bangladesh, England, Sri Lanka, West Indies and Zimbabwe
- Kohli average almost 50 against all the nations he has played – Australia, Bangladesh, England, New Zealand, Sri Lanka and West Indies
- Gavaskar averages 50 against Australia, Pakistan, West Indies, Sri Lanka

par(mar=c(4,4,2,2)) batsmanAvgRunsOpposition("./tendulkar.csv","Tendulkar") batsmanAvgRunsOpposition("./kohli.csv","Kohli") batsmanAvgRunsOpposition("./gavaskar.csv","Gavaskar")

### 7. Get player data special

This is required for the next 2 function calls

### 8 Get contribution of batsmen in matches won and lost

Kohli contribution has had an equal contribution in won and lost matches. Tendulkar’s runs seem to have not helped in winning as much as only 50% of matches he has played have been won

par(mfrow=c(2,2)) par(mar=c(4,4,2,2)) batsmanContributionWonLost("tendulkarsp.csv","Tendulkar") batsmanContributionWonLost("./kohlisp.csv","Kohli") batsmanContributionWonLost("./gavaskarsp.csv","Gavaskar")

a

### 9 Performance of batsmen at home and overseas

The boxplots show that Kohli performs better overseas than at home. The 3rd quartile is higher, though the median seems to lower overseas. For Tendulkar the performance is similar both ways. Gavaskar’s median runs scored overseas is higher.

par(mfrow=c(2,2)) par(mar=c(4,4,2,2)) batsmanPerfHomeAway("tendulkarsp.csv","Tendulkar") batsmanPerfHomeAway("./kohlisp.csv","Kohli") batsmanPerfHomeAway("./gavaskarsp.csv","Gavaskar")

### 10. Moving average of runs

Gavaskar’s moving average was very good at the time of his retirement. Kohli seems to be going very strong. Tendulkar’s performance shows signs of deterioration around the time of his retirement.

par(mfrow=c(2,2)) par(mar=c(4,4,2,2)) batsmanMovingAverage("./tendulkar.csv","Tendulkar") batsmanMovingAverage("./kohli.csv","Kohli") batsmanMovingAverage("./gavaskar.csv","Gavaskar") #dev.off()

### 11 Boxplot and histogram of runs

Kohli has a marginally higher average (50.69) than Tendulkar (48.65) while Gavaskar 46. The median runs are same for Tendulkar and Kohli at 32

### 19. Check batsman in form

As in the moving average and performance forecast and cumulative average runs, Kohli and Gavaskar are in-form while Tendulkar was out-of-form towards the end.

checkBatsmanInForm("./tendulkar.csv","Sachin Tendulkar") ## [1] "**************************** Form status of Sachin Tendulkar **************************** \n\n Population size: 294 Mean of population: 50.48 \n Sample size: 33 Mean of sample: 32.42 SD of sample: 29.8 \n\n Null hypothesis H0 : Sachin Tendulkar 's sample average is within 95% confidence interval of population average\n Alternative hypothesis Ha : Sachin Tendulkar 's sample average is below the 95% confidence interval of population average\n\n Sachin Tendulkar 's Form Status: Out-of-Form because the p value: 0.000713 is less than alpha= 0.05 \n *******************************************************************************************\n\n" checkBatsmanInForm("./kohli.csv","Kohli") ## [1] "**************************** Form status of Kohli ****************************\n\n Population size: 117 Mean of population: 50.35 \n Sample size: 13 Mean of sample: 53.77 SD of sample: 46.15 \n\n Null hypothesis H0 : Kohli 's sample average is within 95% confidence interval of population average\n Alternative hypothesis Ha : Kohli 's sample average is below the 95% confidence interval of population average\n\n Kohli 's Form Status: In-Form because the p value: 0.603244 is greater than alpha= 0.05 \n *******************************************************************************************\n\n" checkBatsmanInForm("./gavaskar.csv","Gavaskar") ## [1] "**************************** Form status of Gavaskar ****************************\n\n Population size: 125 Mean of population: 44.67 \n Sample size: 14 Mean of sample: 57.86 SD of sample: 58.55 \n\n Null hypothesis H0 : Gavaskar 's sample average is within 95% confidence interval of population average\n Alternative hypothesis Ha : Gavaskar 's sample average is below the 95% confidence interval of population average\n\n Gavaskar 's Form Status: In-Form because the p value: 0.793276 is greater than alpha= 0.05 \n *******************************************************************************************\n\n" #dev.off()

### 20. Performance 3D

A 3D regression plane is fitted between the the Balls faced, Minutes at crease and Runs scored

### 20. Runs likelihood

This functions computes the K-Means and determines the runs the batsmen are likely to score.

par(mar=c(4,4,2,2)) batsmanRunsLikelihood("./tendulkar.csv","Tendulkar") ## Summary of Tendulkar 's runs scoring likelihood ## ************************************************** ## ## There is a 16.51 % likelihood that Tendulkar will make 139 Runs in 251 balls over 353 Minutes ## There is a 25.08 % likelihood that Tendulkar will make 66 Runs in 122 balls over 167 Minutes ## There is a 58.41 % likelihood that Tendulkar will make 16 Runs in 31 balls over 44 Minutes batsmanRunsLikelihood("./kohli.csv","Kohli") ## Summary of Kohli 's runs scoring likelihood ## ************************************************** ## ## There is a 20 % likelihood that Kohli will make 143 Runs in 232 balls over 330 Minutes ## There is a 33.85 % likelihood that Kohli will make 51 Runs in 92 balls over 127 Minutes ## There is a 46.15 % likelihood that Kohli will make 11 Runs in 24 balls over 31 Minutes batsmanRunsLikelihood("./gavaskar.csv","Gavaskar") ## Summary of Gavaskar 's runs scoring likelihood ## ************************************************** ## ## There is a 33.81 % likelihood that Gavaskar will make 69 Runs in 159 balls over 214 Minutes ## There is a 8.63 % likelihood that Gavaskar will make 172 Runs in 364 balls over 506 Minutes ## There is a 57.55 % likelihood that Gavaskar will make 13 Runs in 35 balls over 48 Minutes

### 21. Predict runs for a random combination of Balls faced and runs scored

BF <- seq( 10, 400,length=15) Mins <- seq(30,600,length=15) newDF <- data.frame(BF,Mins) tendulkar <- batsmanRunsPredict("./tendulkar.csv","Tendulkar",newdataframe=newDF) kohli <- batsmanRunsPredict("./kohli.csv","Kohli",newdataframe=newDF) gavaskar <- batsmanRunsPredict("./gavaskar.csv","Gavaskar",newdataframe=newDF) batsmen <-cbind(round(tendulkar$Runs),round(kohli$Runs),round(gavaskar$Runs)) colnames(batsmen) <- c("Tendulkar","Kohli","Gavaskar") newDF <- data.frame(round(newDF$BF),round(newDF$Mins)) colnames(newDF) <- c("BallsFaced","MinsAtCrease") predictedRuns <- cbind(newDF,batsmen) predictedRuns ## BallsFaced MinsAtCrease Tendulkar Kohli Gavaskar ## 1 10 30 7 6 4 ## 2 38 71 23 24 17 ## 3 66 111 39 42 30 ## 4 94 152 54 60 43 ## 5 121 193 70 78 56 ## 6 149 234 86 96 69 ## 7 177 274 102 114 82 ## 8 205 315 118 132 95 ## 9 233 356 134 150 108 ## 10 261 396 150 168 121 ## 11 289 437 165 186 134 ## 12 316 478 181 204 147 ## 13 344 519 197 222 160 ## 14 372 559 213 240 173 ## 15 400 600 229 258 186 #dev.off()

## Key findings

- Kohli has a marginally higher average than Tendulkar
- Tendulkar has the best strike rate of all the 3.
- The cumulative average runs and the performance forecast for Kohli and Gavaskar show an improving trend, while Tendulkar’s numbers deteriorate towards the end of his career
