Why is a change required?
The World Test Championship (WTC) is about to start.
Pakistan don't play against the West Indies, but they do play 3 of their 6 qualifying series away in Australia, England and New Zealand.
That is important for two reasons. Firstly, as I am about to show, in those conditions Yasir Shah has a terrible record as a bowler while Shadab Khan has been decent with the ball and important with the bat.
Secondly, Pakistan simply MUST play 4 quick bowlers in their WTC qualifiers in those three countries. That then raises a question as to whether they can also pick a specialist spinner, or can only accommodate an all-rounder like Shadab Khan or even Imad Wasim.
We all recognise that Australian and South African conditions are interchangeable, and that England and Ireland are similarly identical to one another as venues.
Performances in the West Indies are irrelevant, as Pakistan doesn't play them in the WTC.
So let's compare the bowling - and batting - of Yasir Shah in the places where Pakistan must play:
1. In England and Ireland
YASIR SHAH:
19 wickets in 4 Tests, average 40.73
92 runs in 4 Tests at an average of 15.33
SHADAB KHAN:
7 wickets in 3 Tests, average 34.43
171 runs in 3 Tests at an average of 42.75
2. In Australia, New Zealand and South Africa
YASIR SHAH:
9 wickets in 6 Tests, average 95.11
81 runs in 6 Tests at an average of 9.00
SHADAB KHAN:
4 wickets in 1 Test, average 20.00
52 runs in 1 Test at an average of 52.00
These numbers are absolutely shocking, damning even.
They show that in Australia, New Zealand and South Africa Yasir Shah is absolutely hopeless with both bat and ball.
Pakistan don't have to tour South Africa in the World Test Championship, but Yasir Shah's dismal record there this January - when he achieved a quarter as much in 2 Tests as Shadab Khan did in 1 Test - proves that he cannot be taken to Australia this November.
For the record, this is what Yasir Shah and Shadab Khan each achieved in South Africa in January 2019:
Yasir Shah in South Africa 2018-19:
4-0-24-0
7.4-1-20-1
21-1-79-0
4, 0, 5, 5
Shadab Khan in South Africa 2018-19
10-2-39-1
11.3-0-41-3
0, 52 not out.
To be fair, you can argue that at the two driest English grounds, Lords and The Oval, Yasir Shah took five wicket hauls in 2016. But can you carry such a non-performing bowler who can't bat when his performances outside Asia are not improving, but actually getting worse?
Shadab Khan is not a good enough spinner to be the main spinner in Asia. But outside Asia a spinner is essentially a specialist lower-middle order batsman who can bowl a few overs on Days 1-4 to rest the quicks.
The evidence is clear: Shadab Khan is a far more viable spinner where Pakistan have to play their World Test Championship qualifiers than Yasir Shah is.
