Best Death Bowlers In IPL In Recent Years: A Statistical Case Study

 

Bowling Strike Rate:

Death bowlers in IPL
  • There have been 9 bowlers who take less than 10 balls for each dismissal, with Kuldeep Yadav being the lone spinner. Kagiso Rabada has the best strike rate (8.00), followed by Mohammed Shami (8.14) and Kuldeep Yadav (8.40).
  • Deepak Chahar, despite having an impressive strike rate (8.43, fourth-best), gets nearly 1 over per match in death overs.
  • Among bowlers who bowl more than 10 balls per innings, only Rabada has a strike rate below 10, while Jofra Archer has the worst strike rate (15.43)
  • 4 bowlers have picked 30 or more wickets; Bhuvneshwar Kumar (47), Jasprit Bumrah (45), Dwayne Bravo (32) and Jayev Unadkat (30)

Dot ball and Non-boundary ball Percentage:

Death bowling in IPL Dot ball percentage
  • Krunal Pandya (7.57), R Ashwin (7.77), Mustafizzur Rehman (7.87), and Deepak Chahar (7.93) are the only bowlers with an economy below 8.
  • 5 of the 10 bowlers with the best economy are spinners, most of whom bowl in the sixteenth or seventeenth overs.
  • Navdeep Saini has the highest dot ball percentage in death overs, but a comparatively lower non-boundary ball percentage.
  • Rashid Khan has been really difficult to get away with in the death overs, with more than one-third of his balls being dot balls and less than one-fifth of balls being hit for boundaries.

Impact Factor:

Impact Economy – An impact economy of +1 indicates the bowler concedes 1 run less than other bowlers in all the matches the particular bowler was involved in. The negative impact economy indicates the bowler has conceded more than the rest of the bowlers.

Impact Strike Rate – An impact strike rate of +1 indicates the bowler takes 1 delivery less than other bowlers to pick a wicket in all the matches the particular bowler was involved in. The negative impact strike rate indicates the bowler has taken more deliveries to dismiss a batsman than the rest of the bowlers.

Impact Average – An impact average of +1 indicates the bowler concedes 1 run less than other bowlers to pick a wicket in all the matches the particular bowler was involved in. The negative impact average indicates the bowler has conceded more runs to dismiss a batsman than the rest of the bowlers.

  • pinners in the death overs; Narine, Jadeja, R Ashwin, Rashid Khan and Tahir, all have been on the economical side but not amongst the wickets. This is probably as they hardly bowl in the last three overs and batsmen look to play them out before launching the attack on the pacers.
  • In the limited opportunities he has got, Deepak Chahar has been a regular wicket taker and also has a positive impact economy, proving how important an asset he was for CSK in 2019.
  • The likes of Ishant Sharma, Umesh Yadav, Basil Thampi and Jaydev Unadkat have to be used better by their captains by minimising their overs at the death.
Death bowling in IPL
  • Navdeep Saini, despite having a 9-plus economy in death overs, concedes 2.5 runs less than rest of the bowlers in the games he is involved in.
  • Deepak Chahar takes nearly 9 balls less than other bowlers for each dismissal in death overs. He concedes almost 1 run less than all bowlers in the matches he has played, despite bowling all his overs from overs 18-20.
  • The likes of Shami and Rabada have been average in terms of economy, but take wickets quite frequently.
Death bowling in IPL
  • Deepak Chahar is miles ahead of anyone else who have frequently bowled in the last three overs. He is ahead of the second placed Mitchel Johnson by almost 5 points.
  • The more regular death bowlers like Bumrah, Bhuvneshwar and Malinga have a positive impact factor but not very far ahead of others as they are believed to be. (The performance in crunch games is not considered here, which is of course a major reason why they are regarded so highly)
  • Among bowlers who bowl more than 50% of their death over deliveries in last 3 overs, only Jaydev Unadkat has a negative impact factor, mostly due to his highly negative impact economy.
Death bowlers in IPL
  • Among the regular death bowlers, Malinga despite having a negative impact on economy, proves his worth with consistent wickets.
  • The likes of Archer and Mustafizur have been on the economical side, despite not being amongst wickets.
  • Tim Southee, Jaydev Unadkat and Trent Boult have been consistently shown faith upon by the management despite not been up to the mark in death overs.

The Crucial Three Overs:

True Economy, True Strike Rate and True Average – Difference in Economy, Strike Rate and Average between overall numbers excluding the player and the numbers for the player.

A positive True Economy/Strike Rate/Average indicates the player has performed better than average and the number quantifies the magnitude.

OPFrf-deviation-in-economy-rate-in-last-
  • Among 20 bowlers who have bowled the most deliveries in the last 3 overs, Chris Morris concedes nearly 3 runs less than the average runs conceded in those overs. He has been one of those bowlers whose economy actually gets better in the end overs.
  • Umesh Yadav has been terrible at the death and leaked way too many runs. Quite clearly he has been over-utilized at the death, especially in the last 3 overs.
  • The like of Unadkat, Thakur and Bravo have also leaked runs more than average. And we have seen Dhoni minimising Bravo’s overs at the death in the last two years.
Death bowling in IPL
  • Chris Morris, Deepak Chahar, Nathan Coulter-Nile, Mohammed Shami, Lasith Malinga, Navdeep Saini and Kagiso Rabada have been quite impressive in the last 3 overs. Malinga’s numbers in overs get better in overs 18-20 as compared to overs 16-17, indicating how crucial a man he is under pressure.
  • The likes of Umesh Yadav, Shardul Thakur and Dwayne Bravo have been far from impressive in the last 3 overs.
  • Narine and Rashid have been economical, while Rabada, Perera, Shami have been amongst the wickets and have a scope to improve in economy.

The overall analysis gives a clear idea on how some bowlers need to be used better; some are under-utilised and some over-utilized in death overs. There are a few games where the players with negative impact in this analysis have turned out to be match-winners, but they certainly need to work on their consistency.

Is R Ashwin An Underrated T20 Bowler; How Do The Numbers Stack Up?

 

Ravichandran Ashwin, who rose to limelight as a crafty and skillful finger spinner, specialized in bowling the powerplay overs in T20 cricket, is now out of contention for the national side for more than 3 years now. Post the Champions Trophy 2017, the Indian team management has emphasized on wrist spinners in the limited overs games, which has resulted in R Ashwin being overlooked since then. But does his performance justify this?

Overall International Numbers:

Ashwin T20I

With an impressive economy rate of 6.97 and Strike rate of 19.70, R Ashwin has done a brilliant job so far in the T20Is. However, these numbers do not portray the complete picture. Let us look at how his numbers stack up against all other bowlers involved in the games Ashwin has been a part of:

 

Ashwin in international T20 games has clearly been better than rest of the bowlers playing in the games Ashwin was a part of.

  • Ashwin has conceded 0.82 runs per over less than all other bowlers in the games in which he played
  • With a strike rate of 19.70, Ashwin takes nearly 2 balls less than other bowlers for each dismissal.

Let us look how has Ashwin fared as compared to all other spinners playing in the games Ashwin was a part of:

ashwin in t20i
  • R Ashwin has taken nearly 6 balls less and conceded nearly 7 runs less per dismissal than all spinners who bowled in the games Ashwin was a part of, while conceding 0.22 runs less per over.
  • Also, Ashwin has taken 0.57 wickets more than the other spinners playing in the games Ashwin was involved in.

IPL numbers and Stats:

A look at the phasewise comparison between R Ashwin and all other spinners who bowled in the games Ashwin played:

ashwin in powerplays
  • In Powerplays, R Ashwin has taken 11 balls (nearly 2 overs) less than other spinners for each dismissal.
  • While there is not much difference in checking the run flow (dot percentage and runs on non-boundary balls), Ashwin has conceded lesser boundaries, with almost 2 balls more than other spinners for each boundary, owing to his lower economy.
ashwin middle overs
  • The numbers are not much different when it comes to middle overs, except for the fact that Ashwin concedes boundaries a little less frequently (nearly 2 balls more than other bowlers for each boundary).
ckRPi-r-ashwin-vs-spinners-in-death-over
  • In death overs, Ashwin conceded nearly 1.5 runs per over less than other spinners and has taken 3 balls more to concede a boundary.

Overall, when we compare R Ashwin with other spinners in the games that he has played, the Chennai-based finger spinner has been way ahead in both wicket-taking ability and economy in the powerplays, there is not much difference in the middle overs while being much more economical in the death overs.

Let us have a look at how Ashwin’s numbers satck up against all bowlers who bowled in the games Ashwin played in:

[Relative “parameter” = Ashwin’s numbers – Other bowlers’ numbers]

R Ashwin IPL
  • R Ashwin in powerplays has been sensational, conceding 1.20 runs per over less than others while taking nearly 6 balls less than others for picking a wicket .
  • The wicket-taking ability decreases in the remaining phases, but the economy remains better than others as he concedes boundary less often.

Let us find out how has Ashwin performed in recent years in the IPL (since 2015):

ashwin ipl economy
  • While the economy in middle and death overs has not changed drastically, there has been a huge increase in the economy in powerplays (nearly 2 runs per over). Overall economy has also increased by more than 1.5 runs per over.
ashwin strike rate
  • Ashwin’s effectiveness in the powerplays has decreased significantly as he has taken 17 balls more than he did before 2015 per dismissal.
  • The overall strike rate has also taken a dip, which probably has been one of the reasons why he is not in the scheme of things for the national side.
RjQTa-distribution-of-overs-by-phases-in
  • Ashwin has bowled significantly higher percentage of overs in middle overs in recent years. While his powerplay numbers have not been upto the mark leading to him bowling less in that phase, he can certainly be used more in death overs than he is used right now.

Let us have a look at how Ashwin has performed in comparison with all other bowlers he has played with/against.

Ashwin in IPL since 2015
  • While Ashwin has continued to stay highly economical, conceding 1.73 runs per over less than others, his strike rate has taken a massive dip, especially in the powerplays.
  • Death bowling is an area Ashwin has certainly improved upon, having positive impact on all parameters in the death overs phase.
  • While Ashwin has been difficult to hit for boundaries (as evident from his good Relative BpB), bastsmen have found it easier to manoeuvre singles and doubles off his non-boundary balls.

Overall, we can say Ashwin has been exceptional in terms of economy in both T20Is and IPL, but has struggled to pick wickets regularly off late. The strength which he possessed in the initial phase of his career, being the go-to man in the powerplays, has faded away a bit in recent years, which has led to his overall decrease in effectiveness. The numbers in recent years have not done justice to the skill Ashwin possesses, but there is certainly room for much more improvement, especially the wicket-taking ability.

The role might have changed a bit in recent years, making him bowl in a more defensive style, but for Ashwin to be at his absolute best, he must get back to bowling in the powerplays more often and hence his wicket-taking knack.

The Masters Of Chasing In IPL: Best In The Business Since 2017

 

The IPL is one of the most competitive T20 leagues around the globe; the quality of cricket, the unpredictability, the number of games going down to the wire are some of the factors in making IPL a huge success. One thing that it has in common with most other leagues in recent years is the tendency of captains to field first after winning the toss. Chasing in IPL has become the most preferred options in recent years, so much so that the last 4 years have seen more than 80% of times skippers choosing to chase.

Here we have a detailed look at who have been some of the best in the business while chasing totals in the IPL since 2017.

 

  • Parameters include Strike Rotation, Boundary Hitting, Team Contribution, Successful finishing Ability, Death Overs Impact and Consistency.
  • Top 20 percentile of each parameter are categorized as Excellent. The next 4 sections of 20 percentile are classified as Good, Average, Needing Improvement and Poor respectively.

Strike Rotation

What the team does on the non-boundary balls and how they deal when boundaries are not coming easy decides the outcome to a large extent. The strike rotation impact is calculated as the number of runs scored on non-boundary balls.

Strike rotation while chasing
  • Dinesh Karthik and Manish Pandey have scored more than 0.8 runs per non-boundary ball.
  • The likes of KL Rahul, Steven Smith, David Warner and Hardik Pandya have been quite decent with Strike Rotation score in ‘Good’ category while chasing in IPL since 2017.
  • MS Dhoni, Shreyas Iyer, Rohit Sharma have been average, while the likes of Chris Gayle, Quinton de Kock, Kedar Jadhav abd Andre Russell have been poor in strike rotation, scoring less than 0.5 runs per non-boundary balls.

Boundary Hitting:

Boundary hitting refers to the frequency of hitting boundaries. The lower the value, the better it is.

Balls per boundary while chasing
  • Sunil Narine and Andre Russell have been exceptional boundary hitters, hitting a boundary almost every 3 balls, thus making up for the low strike rotation.
  • The likes of Ambati Rayudu, MS Dhoni, Kedar Jadhav and Steve Smith have been poor with boundary hitting, taking more than 7 balls per boundary.

Team contribution:

Team contribution refers to how a player is contributing while chasing in terms of percentage of runs scored and percentage of balls faced.

Team contribution while chasing in ipl
  • Russell and Narine provide excellent value till the time they stay on the crease.
  • The likes of Steve Smith, David Miller, Kedar Jadhav abd Shubman Gill provide a below 90 value (below 100 is considered negative).

Death overs impact:

Death overs impact is the impact a batsman has in the last five overs of a chase, in terms of balls faced in this period per innings and the batting strike rate in this period.

death overs in IPL
  • KL Rahul has been sensational at the death, proving how lethal he can be if he stays longer.
  • The likes of Glenn Maxwell, Kedar Jadhav and David Warner haven’t been up to the mark in death overs and need a lot of improvement.

Consistency:

Consistency of a player refers to his ability to stay on the crease for long and keeping wickets intact. This aspect takes into account the balls per dismissal and batting average of a batsman.

Consistency while chasing in IPL
  • KL Rahul and Shubman Gill have been quite sensational in run chases, keeping their wickets intact and scoring the bulk of runs.
  • MS Dhoni and Dinesh Karthik are the only middle order batsman among top 15 in the list, no doubt they have proved to be so dangerous while chasing and their wickets have so much value.

Successful Finishing:

How often a player stays unbeaten in successful run chases (only innings where a batsman faces a minimum of 6 balls are considered) determines his successful finishing ability.

 

  • Hardik Pandya, MS Dhoni, Dinesh Karthik and Ravindra Jadeja have been the designated finishers and have done their job pretty well.
  • The likes of Krunal Pandya, Shubman Gill, Dwayne Bravo and Yusuf Pathan have also been good finishers.
  • Openers in the list including Shikhar Dhawan, Rohit Sharma and KL Rahul imply their ability to take the side home once set.

Overall Ranking:

Overall Ranking is done based on the overall score which is a cumulative score of all the parameters.

Score of a parameter for a player = Total Players – (Rank of player/Total Players)

Ja68d-top-20-batsmen-with-best-overall-s Ranking the top 20 batsmen while chasing in IPL since 2017 based on six predefined parameters
  • KL Rahul has been the best with the bat in the second innings, having an above-par score in every index, followed by Hardik Pandya, Dinesh Karthik, AB de Villiers and Rishabh Pant.
  • Shubman Gill has been quite underrated, given his excellent numbers while chasing.
  • While the likes of Virat Kohli, MS Dhoni and Andre Russell are absolute match-winners, they fall behind on certain parameters, resulting in their ranks lower than expected.

Teams choosing to field first so often has much to do with batsmen being able to cope up to the pressure better than before. Along with the likes of MS Dhoni, Kieron Pollard and AB de Villiers who are acclaimed finishers, a number of other batsmen including Hardik Pandya, Dinesh Karthik, KL Rahul, Rishabh Pant and Jos Buttler have come to the fore in recent years.

One interesting fact to notice is how important the role of top-order has been while chasing totals and how often their contributions go unnoticed in tight chases. Moreover, once set the likes of Rahul, Dhawan, David Warner, Jos Buttler and Rohit Sharma tend to take their sides home. They have been very good chasers, if not finishers, for sure.

IPL: Most Prolific Batsmen In The Middle Overs Since 2018

 

The Boundary Hitters:

There have been 15 batsmen in the last two seasons who hit a boundary once in every six balls they face in the middle overs.

Batting in middle overs
  • Nicholas Pooran has been the most prolific boundary hitter in the middle overs, hitting a boundary every 3.44 balls. He is followed by Shane Watson (3.80), Sunil Narine (3.93), Andre Russell (4.38), Moeen Ali (4.42).
  • While most of the batsmen in the list are middle-order batsmen, Shane Watson, Sunil Narine, Chris Gayle, Jonny Bairstow, Shikhar Dhawan, and Jos Buttler are some of the openers who have done well in the middle overs as well. These batsmen have gone on to harm the oppositions once set. The frequency at which they hit the boundaries also makes it easier for the incoming batsmen by allowing them time to settle in.

The busy batsmen:

One of the major factors that determine how well someone is doing in the middle overs is the ability to minimize the dot ball percentage.

Middle overs in IPL

 

  • David Warner has been the busiest batsman in the middle overs, with a dot ball percentage as low as 18.05%, followed by Prithvi Shaw (20.18%), Aaron Finch (22.06%), Shane Watson (22.07%) and Mayank Agarwal (23.00%).
  • Most batsmen in the list are openers, which implies to the fact that being set from the beginning helps in churning out runs in middle overs. The ones coming in to bat in this phase tend to take time to settle in and hence more dot ball percentage. The exceptions include AB de Villiers and Rishabh Pant, who also happen to have a good frequency of boundaries in the middle overs.
URO2e-dot-ball-percentage-v-batting-stri
  • The likes of Kedar Jadhav, Dwayne Bravo, and Colin de Grandhomme neither have a good strike rate nor have a low dot ball percentage.
  • Nicholas Pooran, Andre Russell, and Sunil Narine maintain a terrific strike rate despite having a high dot ball percentage, implying their boundary hitting capacity.
  • Shane Watson, David Warner, and Prithvi Shaw have a high strike rate as well as low dot ball percentage, meaning they do not create undue pressure on the batsmen at the other end. These are the kind of batsmen who tend to cause immense damage to the opposition if not dismissed early in the innings.

The Consistent Ones:

x99PO-batting-average-in-middle-overs-in
  • Hardik Pandya has been exceptional with the bat in the middle overs and has maintained a terrific average.
  • Most of the batsmen with a 50-plus average in middle overs are the designated finishers for their side, with Bairstow, Warner, and Williamson being the exceptions. All three of them have played long innings and seen their team through in the last two seasons.
0sIXV-batting-average-vs-strike-rate-in-

 

  • There have been 13 batsmen with an average above 40 and strike rate above 130 in the middle overs in the last two seasons.
  • Shane Watson has proved to be one of the best batsmen in the middle overs, with a strike rate in excess of 180 and an average close to 50. Moreover, he has the second-best boundary frequency and fourth-least dot ball percentage.
  • The likes of MS Dhoni, Dwayne Bravo, and Riyan Parag have a very good average but have a lot of scope for improving their strike rate.
  • Nicholas Pooran and Hardik Pandya have also been terrific in the middle phase, despite having a dot ball percentage on a relatively higher side.
