All Test Ratings on the website are from 01/01/1950 onwards. Our ratings are based on conditions and diverse oppositions. Before the above
mentioned date, there were primarily only two teams which dominated cricket. Moreover, matches were of unequal length with some ending in 4 days
and some being timeless. Post 1950, West Indies and South Africa grew as test teams. Moreover, Asian teams India and Pakistan started improving
after 1950 and became compenent at home at least. Performance in Asia and outside Asia are integral to our overall rating. How the rating works
is explained in highlighted sections. So, here are the Top 15 Non Asian Spin bowlers in matches In Asia
*Note: All Test Ratings are updated till 2022-07-28
NA IN A Rating
This rating only include stats of Non Asian Spin bowlers in matches In Asia. The rating is divided into sections to make it easy to understand how it is calculated. Before each section, its criteria is highlighted in bold. Our ratings are dynamic, and as new matches are played, the rating of earlier bowlers may change if current bowlers set new benchmarks.
The Trend Setter
The Trend Setter (TS) is the player which does the best in a criteria. The rating of all other players are calculated as percentage points of TS. Let’s taken an example to understand it:-
- Let’s assume that Glenn McGrath has taken 500 wkts, which is the highest. This makes him the TS.
- Another player, say Jason Gillespie, has taken 250 wkts.
- If the rating is out of 250, McGrath will get the full points (pts), that is 250.
- The points of Gillespie are calculated as His Wkts/McGrath’s Wkts*250. This comes out to be 125.
- Thus the formula is (Wkts Taken/Wkts Taken By TS)*Max Points.
- All ratings are calculated similarly with Wkts being replaced by the Criteria Stat.
- Obviously, for average the formula is reverased as the lower average is better for a bowler.
- For Average and Strike Rate, a bowler is eligible to be TS only if he has taken a minimum number of wickets, which are mentioned in the qualificaton.
- Lastly, it is to be noted that it is not necessary for a TS to be part of the rating as he might have topped in a criteria but not done well in others.
|Min Wickets (TS AVE SR)||25|
The first criteria Prolific gives points for wkts taken. We have divided cricket from 1950 onwards into 3 broad eras. This has been done to make it fair for players from earlier era, when less cricket was played, and also for current players, who are in the middle of their careers. Let’s take an example:-
- Let’s assume Murlidharan has taken 500 wickets, which is the maximum and gives him 250 points.
- Now, say Underwood in earlier times took 250 wkts, which was the max for his era.
- If there are no eras, he would get 50% of the pts, that is 125.
- Instead of that, we reduced 50 pts (according to %age) from the max to arrive at the figure of 200 pts for Underwood.
- Now, everyone in his era is compared to Underwood and not Murlidharan.
- So a player who has taken 50 Wkts in Underwood’s era will get (50/250)*200 pts or 40pts.
- Eras are calculated by MP, which is the mean of the years a player: First Played (FP) and Last Played (LP).
Criteria: Points For Wickets Taken
|Era 1||MP before 1991|
|Era 2||MP between 1990 and 2016|
|Era 3||MP greater than 2015|
The Comparative Average (C Ave) for bowlers is calculated by taken into account two factors:-
- First is the average of batsmen in the decades the bowler played.
- Second is the average of the opposition batsmen at Home, in Asia or outside Asia; whichever is applicable.
- The average of the opposing team’s batsmen is also calculated by decades.
- Higher C Ave suggest that more runs were scored by the batsmen in the above mentioned factors.
- Thus it was difficult to get Wkts and the bowler will benefit from this.
- Lower C Ave means the opposite.
The Relative Average (R Ave) is calculated using the C Ave. Its formula is (Bowler Ave/C Ave)*A Constant Factor. This constant doesn’t affect the rating as it is the same for everone. If your C Ave is comparatively high, your R Ave will be low; which is better for bowlers. Broadly speaking, the following bowlers will benefit from this system:-
- Bowlers who have played more in unfavourable conditions.
- Asian fast bowlers and Non-Asian spin bowlers whereever applicable.
- Bowlers who have played in an era where the batsmen dominated, like the 2000s
- Bowlers who have played more against top opposition than weaker teams.
Top Teams (TT)
The R Ave Rating is divided into two parts:-
- One is Overall which gives points for the overall R Ave.
- The second part is Against Top Teams, which gives points for R Ave against top teams.
- Win/Loss Ratio is used to determine top teams.
- The top teams are calculated by decades.
- Further, they are divided into In Asia and Outside Asia.
- To be a top team, the team should be among the top teams in the specific condition (Asia or outside Asia) or among the top teams of the decade overall.
- A bowler’s performace is counted in TT if he palyed against it in the specific condition and in the specific decade.
- The Top Teams may be found in the last section of the rating.
Criteria: Points For Relative Average
Against All Teams
|RANK||BOWLER||INNS||RUNS||WKTS||AVE||C AVE||R AVE||RAT|
C SR And R SR
The Comparative Strike Rate (C SR) and Relative Strike Rate (R SR) for bowlers is calculated using the same method as in C Ave and R Ave with average replaced with SR. Points to note are:-
- Bowlers from the earlier era benefit from R SR.
- This is because more balls were taken to get a Wkt back then as batsmen had better defensive technique.
- Rest of the factors are the same as in R Ave
Criteria: Points For R SR or Relative Balls/Wkt
|RANK||BOWLER||INNS||BLS||WKTS||SR||C SR||R SR||RAT|
In this criteria, we have taken the top 5 bowling performances by Wkts of a bowler. Best Bowling By Wickets (BBW) is simply the total wickets taken in the 5 innings divided by 5.
BEST BOWLING (WKTS)
Criteria: Points For Wkts Taken In Top 7 Inns
In this criteria, we have taken the top 5 bowling performances by Average of a bowler. Best Bowling By Average (BBA) is simply the average of the bowler in the 5 Inns. Only 3+ Wkt performaces are counted in this criteria.
BEST BOWLING (AVE)
Criteria: Points For Average In Top 7 Inns
The NA IN A (FC) Rating is the addition of the points of all the above criteria. The rating is out of 1,000. Unfavourable Conditions (UC) is Outside Asia for Spinners and In Asia for Pacers. Favourable Conditions (FC) is the opposite.
