To select the top T20 International (T20I) bowler of the decade, we kept a minimum criteria of taking more than 50 wickets in the period from January 1, 2010 to December 31, 2019. We further narrowed the list by keeping an average of less than 25.00 and an economy of less than 8.00 runs per over in the period. It is to be noted that Rashid Khan of Afghanistan fulfilled all the criteria but he was not included in the list as he mostly played against weak oppositions. Khan had an average of 12.52 and an economy of 6.15 while taking 84 wickets in the period. In all probability, he would have ranked 1st if we included him in the list. Lastly, I would like to remind you that the stats in the article are not the career stats of the players but only their stats in the 2010s. Ten bowlers fulfilled all the above mentioned criteria and these now compete across 11 different disciplines for the title of Stat Sensei T20I Bowler of the Decade.
The 3 most important stats in which a player can earn a maximum of 200.0 points. The other bowlers are given points as a ratio of their performance to the top bowler.
Points given for number of wickets taken in the period

8 other criteria in which a player can earn a maximum of 100.0 points. The other bowlers are given points as a ratio of their performance to the top bowler.
