There's been a lot of talk about the failures of Pakistani spinners at the World Cup. And it's true. They have failed spectacularly .
But theres a reason why they are failing over and over again.
Only bowlers who have consistently bowled tight lines are doing well in this World Cup .
You have to finish within a sixth stump line to have any chance of bowling with control.
Look at Adam Zampa's lines against Pakistan
He gave barely any width outside off to cut and kept his speeds(90+ kph) up in order to keep the batsmen honest .
Zampa bowls with a lot of overspin and attacks the stumps throughout .
Attacking the stumps is easier for offspinners , left arm spinners who have good arm balls and left arm wrist spinners whose stock balls turn into the stumps.
It's harder for leg spinners because their turn the ball away from the stumps and you need Zampa's or Rashid Khans skills levels to bowl googlies, flippers and top spinners at high pace and with great accuracy.
Shadab and Usama Mir are looking to flight the ball with revs and coming over-the-top a lot more. What that means is they are prone to over pitching and drag downs and are easier to hit.
This is because the batsmen are able to get under their deliveries to hit over the top of play them off the backfoot when they drag it down. Also since they are looking to spin it away from the stumps, they are getting cut as well.
You can find success with that method but it's very difficult and you'll have to rely a lot more mistimed hits going to fielders.
Adil Rashid doesn't attack the stumps as often.
But what he does when looking to spin it away is to bowl very slowly at around 70 kph , so that batsmen have to generate power and so that ball grips and turns more.
His dismissal of RVD is a perfect example of slowing it down to get big turn and entice the false shot.
Usama Mir in particular can benefit from dropping his pace a lot and looking to rev it as much as possible and inducing false shots .
Pakistani spinners are not doing either consistently and that's why they are neither able to get "pressure" wickets like Zampa or able to get wickets like a classical leggie(Adil) does.
