A review of team and individual performances in T20Is in the calendar year 2021.
As discussed here, for any meaningful comparison, we should not consider all T20Is but only those of a reasonable standard (i.e. those who have or had Test or ODI status in the past). These are:
- Afghanistan
- Australia
- Bangladesh
- Bermuda
- Canada
- England
- Hong Kong (HK)
- India
- Ireland
- Kenya
- Namibia
- Nepal
- Netherlands
- New Zealand (NZ)
- Oman
- Pakistan
- Papua New Guinea (PNG)
- Scotland
- South Africa (SA)
- Sri Lanka (SL)
- United Arab Emirates (UAE)
- United States of America (USA)
- West Indies (WI)
- Zimbabwe
We first look at the performance of teams:

Among the teams which have played at least 10 matches, Pakistan has the best W/L ratio followed by South Africa and England. Zimbabwe brings up the tail with Ireland just above it.
Now for individual performances, starting with Batting
Most runs (300 and above):

Note that Mohammad Rizwan has by far the most runs, with his team-mate Babar Azam in second place. No one has scored more than one century. Rizwan has the most 50+ scores (13), followed by Azam (10).
The most runs by an Indian player are 424 by RG Sharma, in the middle of the table above.
Highest innings (80 and above):

Led by Babar Azam (122). The best for India is 80* by V Kohli.
Highest batting averages (Minimum 20 innings, all instances):

Inevitably headed by Rizwan, whose average is almost double that of the runner-up Azam. Nobody from India has played enough.
Highest strike rate (Minimum 250 balls faced, all instances):

Here WI’s E Lewis leads, followed by RG Sharma. No one else from India. The Pakistani pair of Rizwan and Azam are in the middle.
To be continued.
