An attacking slow bowler, Shah was dropped for the second Test of Pakistan’s tour of New Zealand as they opted for a four-pronged pace attack on a green seaming Seddon Park pitch in Hamilton.
Doubt also surrounded Shah’s fitness in the lead up to the first Test after he sent a scare through the Pakistan camp when he pulled up with a back injury ahead of their opening tour match against a Cricket Australia XI in Cairns earlier this month.
Shah was declared fit for his first Test in Australia, but Steve Smith was unconvinced the conditions at the Gabba would be favourable.
“He’s a class bowler. He’s pretty accurate as a leg-spinner, he’s got good skills and we’re going to have to be wary of him in this series,” Australia skipper Smith said.
“At the Gabba you’ll get a bit of extra bounce as a spin bowler, and that can play in your favour as a spin bowler but it can also play against you – your length has to be spot on.
“Generally there isn’t too much turn, it’s more bounce, so length is crucial and if you’re slightly off your length, (batsmen) can really cash in down the wicket and square of the wicket as well.
“So he’s going to have to be pretty accurate.”
Smith scored 40 of his 130 first-innings runs against Yasir, the most off any one Pakistan bowler, while Peter Handscomb also cashed in during his maiden Test century.
Warne said there was enough in the wicket for Shah “to cause the Aussies some real hassle”.
“To use him in a defensive manner, sure there’s a time and place for that, but right now when you’re trying to get back into the game – the only way you can do that is take these wickets,” said Warne, pointing to Australia’s 287-run first innings lead.
“Who’s coming up with these plans? Is it the captain? Is it the bowler? You’ve got to ask the question because it just doesn’t make any sense.”
Pakistan are chasing their first series victory in Australia and has not won a Test here since 1995.
The under-fire Pakistan leg-spinner did hit back to claim the Australian skipper’s wicket on the third afternoon – but not before he has helped Australia extend their lead beyond 400 with a quick-fire 63 from 70 balls.
